Introducing Tesla Service Mode and Service Mode + Livestream Recording

Well, good morning and uh good afternoon depending on where you're at. Uh I want to thank you for joining this live stream. This is the first live stream

stream. This is the first live stream I've done like this and I'm really getting prepared to do a a larger event uh here sometime in the near future. So,

this is letting me set up my test and I appreciate you being here to do that.

We're going to talk about Tesla Tesla service modes. Um, I have been very

service modes. Um, I have been very passionate about the Tesla stuff because we've got uh I've got two Teslas now.

We're now servicing some of those vehicles in our shop. And so we have a poll that's up right now. And so if you can hear me, I just want to get uh some feedback from you. Can you let us know

or answer that poll and uh give us some feedback as to whether or not you're performing any of these uh or services on these vehicles. And then a couple

housekeeping notes here. So, we do have a chat panel. We also have a Q&A panel that we're going to launch uh here in just a second. So, if you have any questions along the way, go ahead and

dump them in the Q&A segment. We'll have

a Q&A segment at the end uh so we can try to wrap up any questions that weren't answered. Um and then, uh let's

weren't answered. Um and then, uh let's see. Is there something else? I need to

see. Is there something else? I need to look at my uh notes there. No, I think that's it.

So, uh let's go ahead and get started.

All right. All right. So, we're going to talk about uh some topics here. We're

going to talk about basic service mode, service mode plus. Uh we're going to go into some Tesla service information. And

uh you should all be aware that Tesla service information now is free. Uh it

doesn't cost you anything. But if you do subscribe to the toolbox application, uh you will need your login to get to that service information because it will

have some other additional uh data. Um,

and so it'll be uh be beneficial. So

let's go to the next slide here.

So why do we want to use uh service mode? Um, well, one, when the car comes

mode? Um, well, one, when the car comes into your shop, it's in this uh you're going to turn off the birectional stuff so that the consumer cannot uh interact

with the with the vehicle and turn on things or turn off things. Uh, you don't want that actually happening.

You also get to turn off the camera recording uh so the customer can't go back to their log and see what's been going on inside the shop.

And then um you're also going to get to you're going to want to u check the service settings. So you'll be able to

service settings. So you'll be able to enable uh the vehicle speed limiter or disable the speed limiter. And then

you're going to want to unlock the gateway. And we're going to walk through

gateway. And we're going to walk through those modes. Okay. So, we're going to

those modes. Okay. So, we're going to look here at service mode.

Um, here we are. So, here's our service mode page that we would typically see.

And just let me explain my setup here. I

do have a connection into a live vehicle. So, I do have a rig where we'll

vehicle. So, I do have a rig where we'll be able to see exactly what's on my screen. And we'll walk through the the

screen. And we'll walk through the the various menus. But when you go into

various menus. But when you go into basic service mode, you can see up here it just says service mode. If you're in service mode plus, it will say service mode plus. Okay. And one of the first

mode plus. Okay. And one of the first things that we're going to go into when we go into the service mode, we'll kind of walk through this panel here, but we want to look at the release notes here.

Tesla has been really uh looking at the aftermarket and making a lot of advancements and bringing a lot of tools to uh to us in the aftermarket. In fact,

there are some tools here for the camera pitch uh aim function which needs to be carried out whenever you change out the windshield or change out the camera. You

used to have to have the toolbox application and it was kind of a tedious thing because you would actually have to request the the car to take a picture of it of an image with a target out in

front of the vehicle properly placed and then you would see what those measurements are and then you would go back and adjust and then repeat that process. very very timeconuming and a

process. very very timeconuming and a lot of times it didn't always work. So,

uh Tesla just brought this right to us right on the screen here. It doesn't

cost anything to get into this. So, um

we'll we'll walk through some of that.

And then the service mode plus, if we look deeper into this, you're going to see you've got some additional things that activate on that screen, including uh can viewer here. And then uh on the

next screen here, you'll see also there's a new panel here for canvas and we're going to walk through that here in just a second. All right. So, let's

let's go to our car here and we're going to hop right in here and go right into service mode. Okay. And to

do that, what we do is we hit the car icon here in the in the lower left and then you hit the software tab. And then

where it says model Y, just on that model, you're going to long press on that for about uh 5 seconds or so. And

then you're going to type in an access code and that's service.

And you hit enter. It's going to warn you. It says that you need to be a

you. It says that you need to be a service professional so that we're not, you know, not causing any problems. So, we're going to go ahead and enable.

And one thing, one first thing to note is that if you're in a hot climate condition or a cold climate condition, um it turns off the climate control system the moment you enter. So if it's

super hot, you want to turn the air back on, you can just touch the temperature indicator down there at the bottom and that turns everything back on uh for you. I'm going to actually just turn it

you. I'm going to actually just turn it off. Okay, so I mentioned the release

off. Okay, so I mentioned the release notes. So we want to click through here.

notes. So we want to click through here.

This is a really a good place for you to find out what Tesla's been adding uh and what things that you might want to go out and check and uh and explore. Um so

this is the latest the one up at the top, but I'll go back down to the very bottom. You can see that uh they started

bottom. You can see that uh they started this. They they put a new high voltage

this. They they put a new high voltage panel in, enhanced steering panel, enhanced high voltage interlock loop panel, low voltage panel, uh some falcon

door stuff, some steering column stuff, and then a camera clear and camera pitch stuff. And I do have a um I have a

stuff. And I do have a um I have a target out in front of this car. So,

we're going to actually see that when we get to the uh uh driver assistance stuff. uh this update after that. You

stuff. uh this update after that. You

can explore that. And then um the next one, you can see this new brakes panel.

Uh pretty cool stuff for burnishing in the brakes. If you ever find yourself

the brakes. If you ever find yourself replacing brake pads, which um you know, in certain climates, you may actually have to do brake work, but in most cases, these vehicles probably won't

need brake pads. And then there's the uh the last one. Okay, so we can close out of this panel.

We've got the VIN, we've got the mileage, we've got a little more info about the vehicle here. And then uh down at the bottom here, bottom right, we have service settings. So, this is where

you would go in and you would remove your speed limiter so you can actually road test the car. Uh you've got a touch check here that basically lets you check the screen. So, you can do two fingers

the screen. So, you can do two fingers at a time, three. So, if somebody's complaining that they, you know, can't get the screen to, uh, respond, uh, you can come in here and test that out. And

then to get out of it, it says to tap the two corners on the display simultaneously. Any two corners, I

simultaneously. Any two corners, I think. All right. And so, that brings

think. All right. And so, that brings you back. And you'll see at the lower

you back. And you'll see at the lower tray, we've got that big wrench uh, red icon here. So, we click on that, and

icon here. So, we click on that, and that brings us back in there. If you

touch the additional resources, it's telling you about the other information that you can get on Tesla or service.esla.com.

service.esla.com.

Um, complimentary service manuals, parts manuals, do-it-yourself stuff. Uh,

additional diagnostic software. So,

that's the toolbox stuff. We're going to explore that. And then it's talking

explore that. And then it's talking about what else is available. We're

going to go through those here. Um,

you've got service alerts. So, if you click the service alerts, you're seeing right now I'm seeing a bunch of service alerts here. And you

know, when it says a an AO96 or an A, that means that's an alert. And then

there's some that are W. So, those are warnings. And if you scroll down here,

warnings. And if you scroll down here, you can see um you see the little waveform at the end of the report there. And that means that

there's a payload of data, additional um alert information. And so in this one

alert information. And so in this one here, there's actually just one line there. BMS A170 limp mode active uh

there. BMS A170 limp mode active uh false for whatever that code is. U going

to go down to the bottom down here because there was a couple that I recall.

Um I set a bunch of alerts here. Just

messing with the car here. So this is uh says one or more messages the vehicle controller receives periodically for the front front row passenger optic uh occupancy classification

um not received and then there's some alert payload data there. So and then you can go look at the customer uh what the customer facing um alerts that they get and then you can just look at all of

the alerts uh and go through them. So

one word of caution on the alerts is that uh it's been my experience that you find a lot of alerts are false failures

and um so beware uh there there may be some conditions here that you you don't want to chase uh you know chase something that doesn't that there is no fix for and a lot of times there may be

a software update that comes down the road to to solve for that particular problem. uh we have a software reinstall

problem. uh we have a software reinstall panel and you know it's telling us basically don't use it when you're changing the car computer because that basic that

module has basically all the software for all the other modules. So when you want to change out a module or you're replacing one um you can hit reinstall and it'll go out there and reinstall all

the software for the different modules.

And then we have this brake burnishing um option here. And it's also under the chassis uh button as well. But this is pretty cool. This and it's going to give

pretty cool. This and it's going to give us a warning here. Um the regen gets turned off because of course we we want to disable regen. So we can actually use

the brakes to uh slow the vehicle down.

And this gives you a guided operation.

And what it tells you that's going to happen here, it says you've got to select some road conditions that's going to allow you to to accelerate up to 50 mph and then back back down to zero. And

you need to do that for 10 times. But it

will basically have you press the brake hard enough to hit the target range, which is 34 bar. So I'm going to press on the brake pedal right now. Okay. And

I'm going to start pressing down. You

can see there's there's my 34 bar. So,

there's about how hard I need to press on the brake. And it will actually give you some audible uh prompts uh to help you run this uh operation. So, we're

going to go ahead and uh back out of that, of course. And uh Okay. So, now

the next one we're going to go to is driver assistance. So, in the driver

driver assistance. So, in the driver assistance, we have cameras. And when we click on cameras, we are now seeing um over in the right there, we can see the

fisheye pitch and the main pitch. So,

those are the the continuous adaptive um offsets that are being applied to that um as we're driving down the road. If we

want to touch on any of those cameras, we can see what they are. It says camera type is RGGB. So, that's red, green, green, blue. Uh the previous model, so

green, blue. Uh the previous model, so this is a uh what's called a hardware 4 vehicle, and it only has two cameras in the front. The previous uh system

the front. The previous uh system hardware 3 actually has a triple camera and the cameras are RCCB so that the normally green channels are actually

clear and uh so there's been a lot of computer science uh machine vision science around uh you know these perception systems. So, they're

continuing to adapt, update cameras, and uh, you know, make sure that they're providing all the data for the vehicle.

Over on that left panel here, we see the ECU, primary A and B, uh, normal, the statuses. And then we've got uh this

statuses. And then we've got uh this when they're green icons, you there everything's available. And then below

everything's available. And then below that, we have SATs. Uh, so this vehicle has been sitting inside the building for for a while. So, we currently don't have any satellites in in view. Uh, normally

you'll see, you know, a number of, you know, nine or more, sometimes 12. And

then it will also have a green indicator next to dead reckoning. Now, one word of caution here. I have had uh some

caution here. I have had uh some different equipment in my car to collect data, record data, and I've actually had some situations where um it has affected

that satellite accuracy and gotten warnings on that. And I I'll probably do a video on that in the future to uh kind of highlight what's going on there. But

this is one area to go check. Um what I found was that when I was having that interference problem, I went to look at this satellite stuff. Everything was

green, but it only showed like one satellite in use when the car is, you know, out in the open. So that was a clue that there was something going on with the uh system. unplugging my

equipment, removing it from the car.

Actually, it reenabled all that uh that data. Um and then uh so you can ping the

data. Um and then uh so you can ping the the system to kind of wake it up. You

can reset it. You can clear the camera calibration. And then it's going to

calibration. And then it's going to cause uh cause you to take the car out and drive it. And then we can go here to camera preview. All right. So, I'm going

camera preview. All right. So, I'm going to touch that. It's giving us a warning that there's nothing here being recorded, but of course, we are recording. Okay. Um, and so the first

recording. Okay. Um, and so the first thing we're looking at is actually this main uh screen. And that's the main camera. This is the wide camera. Okay,

camera. This is the wide camera. Okay,

wide camera. Look. Uh, so in service information, it tells you to set up that target. Some of you that have been doing

target. Some of you that have been doing uh targeting uh camera calibration may recognize that target. That is, yes, the Hyundai Kia target. This is the one

that's also used for Tesla, but it's not used for any type of adaptation from the camera. It's just to look at the

camera. It's just to look at the measurement and see where this uh these these lines are. And you see that piece of tape there that I've got added to the

the target. It's just above the blue

the target. It's just above the blue line. Um that's supposed to line up the

line. Um that's supposed to line up the top of that edge is supposed to line up with that that blue line. So really the camera is it looks like it's pitched

down a little bit, but surface information says if that falls in between these two green lines, you're okay. If I go to the wide view, uh same

okay. If I go to the wide view, uh same thing. We're we're okay on that one.

thing. We're we're okay on that one.

Okay. We can also look at the different panels. So I've I've got the uh this is

panels. So I've I've got the uh this is a left door pillar. So this is on the B-pillar looking left forward. So, you

can kind of see my setup here and my my helper Johnny over there that's helping us um um do this show here. Uh we're

looking at the left uh repeater. So,

this is what you would see when you're hitting the turn signal. There's the

right door pillar and then the right fender. Okay. And then you scroll over,

fender. Okay. And then you scroll over, you can look at the rear view as well.

All right. So, we're going to go to the next panel down here. And do we have any questions that have uh popped in here yet?

Yeah. Wayne wants to know if the customer has birectional data while the vehicle is being serviced.

Uh, say that one more time. I I didn't quite hear that.

Wayne, he wants to know if the customer has birectional data while the vehicle is being serviced.

So, this is why you want to put it into to uh into service mode. Okay. And

when you put it into service mode, they do they no longer have access to the uh the info. And I'm we're actually

the info. And I'm we're actually starting the Q&A now, so you go ahead and add your stuff in there. Um, so

hopefully that that answers your question.

Um, okay.

So, yeah, you don't want the customer doing anything. And also, they can look

doing anything. And also, they can look at the live preview um on the camera.

Uh, they can pull up the live preview for you. uh so they can pull up their

for you. uh so they can pull up their phone, they can actually look at some of the camera inputs while the car is in your shop. So you definitely want to

your shop. So you definitely want to turn that off, you know, unless you want them to see that, but uh you normally want that off. That way they can't turn on the air conditioning system or turn on the seat heaters, roll the windows

down, that kind of stuff. So you you want to disconnect them. Okay, so let's go back in the car here and uh take a look at the infotainment here. We're

going to hit connectivity and it's showing us some, you know, the Wi-Fi status, Tesla connection, um the antenna information and all that. And you've got a couple of test options down at the

bottom.

We've got software uh information here.

So, you've got infotainment and there's two banks of data. So, you can see there's two gigabytes in each of those banks. Uh, it shows you what version it

banks. Uh, it shows you what version it is. Shows you if there's any failure

is. Shows you if there's any failure counts that are excessive and whether or not there's a staged update, um, and any other failures over here on the right on

the autopilot system. And then also on the map uh, map data. So, you can get the uh, information on that. And then

down on the lower right, we do have E ECU update status. And that is mentioned in the release notes um, on um, some of the updates that have come in. So you

can see the last uh firmware job uh what that version number was, the ECUs that were actually updated, and then version matched ECU. Down at the bottom here, we

matched ECU. Down at the bottom here, we have 63. And if we click on that, it

have 63. And if we click on that, it will u show you all the different modules that have matching software.

Okay, so everything uh everything looks good there. Uh next, we're going to go

good there. Uh next, we're going to go to the charging um tab. So, this is somewhere where you can maybe as you're plugging the car into a charger and you want to check some of the data uh from

the charger, uh this will help you do some uh diagnosis on that. Uh the HV charging information,

um the state, state of charge, uh the Hville, um and the pyro fuse. And then

below that, you see there's a battery health. You can run a health check on

health. You can run a health check on these systems, but it will take you 24 hours. And this will tell you, it'll

hours. And this will tell you, it'll prompt you to set the car up. And it

basically says that uh they want the vehicle plugged into a charger that can do greater than 6 kilowatts uh on on AC.

Okay? And that the state of charge is less than 50%. Okay? And then you're going to turn off all of the summon sentry mode um and automatic uh preconditioning. take you're going to

preconditioning. take you're going to turn all that off and then you the car is going to need to sit and what it will do it'll drain that battery down and then it will charge it back up and uh

and it's looking for information you know and it's going to give us a a status u of of health. So this car is fairly new. I haven't run this test yet.

fairly new. I haven't run this test yet.

So uh you can see the contacttor state and then a DC link. Um there we can look deeper at the battery itself. You can

see that the battery currently is we're at 29%. Also has some shipping

at 29%. Also has some shipping information down here uh to let you know that ground sheet C shipping is okay right now and that uh you would have to

actually bring it down below 28% state of charge if you're going to return this via air. So, you know, if you're in a

via air. So, you know, if you're in a mode where you're going to need to replace that uh replace the battery, you need to be aware of this before you get it out of the vehicle. Uh and then there's also a note up here. Uh, it says

tap on components to view more information. So, you can tap on these

information. So, you can tap on these little items here. So, that's the fast charge contacttors over here. There's

the positive contactor. Um, these this is another panel that just popped up.

You can ping different modules and and also run a test. Right. So,

you've got the this test HV PCS interface test. Um, and let's see what

interface test. Um, and let's see what else. Negative contactor. All right. And

else. Negative contactor. All right. And

then this is the Hville.

Um, it gives you some data about uh that system and you can actually run a test.

Okay. So, here's our low voltage panel and we've got power distribution and you can see uh VC front information. You can

reset the VC front. So, that's a vehicle controller front. Um, the lithium ion

controller front. Um, the lithium ion battery information. uh the power

battery information. uh the power conversion system uh data over here on the right and you can see the the type of battery we have as a this is the

lithium ion battery uh setup in this particular vehicle and then this is your home link. So a lot of these cars don't

home link. So a lot of these cars don't come with home link nowadays and you've got to add that in. And uh for this one I did buy the actual home link retrofit

kit and installed it myself. The wiring

harness and everything was all in place.

You had to put a couple bolts in, mount it, and then you run the retrofit uh button there, and it basically deploys the the data through the network. And I

believe this is just on a LIN LIN system. So, it was able to update the

system. So, it was able to update the data, and then I went back and married it to the to activate it uh at my house.

All right. Um the next one we're going to go into is the thermal. Okay. And

before we go there, I want to talk a little bit about thermal management.

Okay. So if you look at our slide here um and we'll go full screen on this Johnny uh the thermal management system on these vehicles are pretty complex and

you know we have to be able to manage uh temperatures and Tesla now has a pretty sophisticated system and there's lots of

learning opportunities here uh to u um you know go through these systems and and I play with this all the time so I can get more familiar with what's uh what's happening with these systems. So

if we go to this panel here, you'll see that we have the what's called the octo valve up here. That device can actually put this cooling system into multiple

configurations. And on the left here, we

configurations. And on the left here, we have the series series radiator bypass mode. Um so you can see the radiator is

mode. Um so you can see the radiator is actually out of the loop up here. See

there's nothing going to it. And the

entire system is in the same loop. We

have both pumps uh going here, the the powertrain pump, the battery pump there running at 6,000 uh RPM. And our flow rate here, you see there 20 L per

minute. So, it's moving quite a bit of

minute. So, it's moving quite a bit of coolant pretty quickly through this system. Uh the one in the center there,

system. Uh the one in the center there, we're running in what's called a parallel mode. So, these two loops are

parallel mode. So, these two loops are isolated from each other. And you can see the one on the left is actually going through the radiator out front.

And that has your powertrain loop, uh, rear drive unit, front drive inverter.

And then over on the right, we have the high voltage battery and the autopilot.

And you can see we're running at 7 L per minute there. Over here on this side,

minute there. Over here on this side, we're at six liters per minute. And we

are also going through the chiller, which we'll talk about refrigeration system here in just a second. And then

over here on the right, we have uh what's called series mode. Um, so we're actually going through the radiator. So

we just added instead of bypassing the radiator, we now have the radiator in uh, play. Uh,

the next there's one other one here.

This is called ambient source. And if we look at this particular one, you'll see that we're we're flowing through the radiator through the chiller. And, you

know, so that's like by itself. And I'll

explain this a little bit further here in just a second. The other side here is just it's it's running through the entire powertrain loop and the battery loop. So, what do you think's going on

loop. So, what do you think's going on here?

It's prepping this system for operation.

Um, and so this next screen here, I'm going to turn on this. We'll take a deeper look here. Go ahead and zoom into that

look here. Go ahead and zoom into that there, Johnny. Okay. So there is a

there, Johnny. Okay. So there is a chiller here that's part of the refrigeration loop. And if we look right

refrigeration loop. And if we look right here, we can see that this chiller is actually active. Okay? And we are

actually active. Okay? And we are running uh refrigerant that's like a an evaporator that's, you know, getting very cold. Well, we've got coolant

very cold. Well, we've got coolant that's running on the other side of that. So we're transferring or we're

that. So we're transferring or we're taking that heat from the coolant and moving it into the refrigerant. Okay?

And so what it's doing is it's prepping that loop so that it can be ready for managing uh elevated battery uh

temperatures that may be happening due to supercharging. And I have seen this

to supercharging. And I have seen this actually happen. Uh back on our thermal

actually happen. Uh back on our thermal management uh over here you can see that um we've got these a series of solenoids or valves here and we'll be able to

click on each of these and and discover which ones they are. as far as identification goes. But you can see

identification goes. But you can see that it can open and close to route refrigerant. If we look up here in the

refrigerant. If we look up here in the top, there is nothing going here into the vehicle. So you have cabin

the vehicle. So you have cabin condensers for heat and we have cabin evaporator. Those circuits are actually

evaporator. Those circuits are actually shut off. So this thermal management

shut off. So this thermal management system in this mode right now is only used it's only being used for managing

the um the loops here for the powertrain system. All right. All right. So, let's

system. All right. All right. So, let's

go back into the vehicle here for a second and we'll jump in. Uh, up at the top here, we do have actions. And you can see system status is at the top. Coolant

not ready for drain refill. Refrigerant

not ready for drain refill. So, why do you think that is? Well, we need to tell that vehicle that we're going to perform that service so that it can open up

systems and make sure that we can drain all the coolant out of it. Same goes

with the refrigeration. If we don't have all the valves open, uh, and we go to recover, you know, we may recover it, may pull it down into a vacuum, but when we go to disconnect certain things, we

may discover have a bad discovery or bad, uh, incident because we had refrigerant trapped in those areas. Uh,

you've got a couple of other items here.

Uh, you've got run coolant pump identification and then you can run some performance tests on the air conditioning system. So, this is a

conditioning system. So, this is a service you could run periodically for your customers cars. Uh, and and it'll actually spit out a report for you. So,

go back to our thermal pad uh page. We

can now look at our refrigeration system. And here, the refrigeration

system. And here, the refrigeration system is off. I'm going to click on each of these um these little items here. There, the little circles there.

here. There, the little circles there.

You've got discharge sensor. The first

one I had was the suction sensor.

And there's our suction temperature and pressure up at the top there, top left.

Our discharge sensor, that's our five bar 23C. And then you've got your little

bar 23C. And then you've got your little valves. So this is a reser expansion

valves. So this is a reser expansion valve, liquid cooled condenser expansion valve, shut off valve, uh cabin

condenser right, cabin condenser left, and then this is a chiller valve. And

then you've got your evaporator expansion valve um control there. And uh

yeah, pretty cool. So, let's just turn on the air conditioning and we'll see this system come up and start running.

All right, compressor is now running. It

gives us an RPM uh that it's running at.

I'm, you know, not asking a lot of the system. The uh ambient temperature is

system. The uh ambient temperature is around 61 degrees and I'm requesting 60 66. So, let's crank it down to the very

66. So, let's crank it down to the very bottom to start making it really cool.

And you should see the compressor start to spin up higher and you'll watch our pressure. So, this is pretty cool that

pressure. So, this is pretty cool that we can actually look at this data and kind of uh we've got we don't even have to hook up our gauges, right? Uh to do an initial assessment on the

refrigeration system. Uh if we go the

refrigeration system. Uh if we go the other way and you'll see that we're running now a liquid cooled condenser.

And I don't know if I mentioned this, but up in the um that screen that we saw earlier, let's go back to our uh presentation deck here. Um up in the

front, all we have is a radiator out out front. We no longer have an an air uh

front. We no longer have an an air uh exchange condenser. The only condenser

exchange condenser. The only condenser is this liquid cooled condenser that's right there. Okay. And uh go back in the

right there. Okay. And uh go back in the car here, John. All right. So you can see we're running through the liquid cool condenser but not the chiller. So

you can see these valves are shut off.

The chiller EXV is shut off. Uh so we we can't actually go in there. Okay. And uh

I'm going to go up to the high end.

We're going to make some heat now. And

you'll see now what happens. We take our condenser out of the loop. We now have a chiller. But our new condenser is

chiller. But our new condenser is actually inside the car, inside the cabin here, and that's where we are going to reject heat um to warm that

cabin air. So, pretty cool stuff. Um you

cabin air. So, pretty cool stuff. Um you

can again watch your your pressures and so on. So, if if you own a one of these

so on. So, if if you own a one of these Teslas or get access to one of these, um you may want to I would encourage you to explore uh especially when you go to a

supercharger.

um you know do your supercharging and watch some of these temperatures and pressures and and watch what's happening. You know, we go back to that.

happening. You know, we go back to that.

We'll go to the coolant panel here.

And this is our coolant panel. We can

see the mode that it's in right now.

We're not running any coolant through the radiator right now. We're going

through the chiller. So, we're in the series bypass or radiator bypass mode.

And um we can see our pump speeds. We

can see our powertrain loop inlet, battery loop inlet temperatures. And

then we can see the temperatures of the autopilot computer, which this is just like a big gaming computer. It's got a coolant loop that goes through it to maintain those temperatures. It is now

getting pretty hot in here. So, I'm

going to turn this turn this down.

And one thing you'll note, I'm gonna actually just turn this AC off. One

thing you'll note here down to the lower left, the rear drive inverter. You see

we don't have any data there, and that's because the drive rails are off. If I

press on the brake pedal here, it's going to turn on the rear drive inverter and the front drive inverter. Now, we

can get some data out of the vehicle.

All right. Um [sighs] All right. So,

let's see. Last thing is the HVAC. So

you can now look at some of the parameters inside the vehicle. Duct

temperatures. Uh it defaults to give you that top view. So we can go to the left view showing us the blower motor. We'll

just turn our AC back on. Blower motor

speed, the floor duct, the panel duct temperature, and also the bleed actuator. And then we can go to the

actuator. And then we can go to the right side and look at the upper actuator, bleed actuator, duct temperature, and so on. So, we'll turn

that back off. All right. So, that's the end of the HVAC. Uh, the next one here is the chassis. And do we have any questions that uh uh came in?

Yeah. Danny wants to know if you can change the settings to PSI and Fahrenheit, for example.

Can we change them oh to from bar? Uh,

not that I'm aware of. So, sooner or later you'll get adopted into the uh metric system. So, start learning the

metric system. So, start learning the metric system. That's what I would uh uh

metric system. That's what I would uh uh do. Um,

do. Um, so all right, and we do have we do have one that came into the Okay, that came into the uh into the Q&A. All right, so

somebody was paying attention. Um, I do see do you need toolbox to open the chiller system or coolant system to perform service evacuate and recharge?

So you do not need the toolbox application. You you can do it here,

application. You you can do it here, which I just demonstrated right on the basic service mode that we got in for for free. Okay. So,

for free. Okay. So,

we're now here on the the chassis tab here, and you've got a couple of or four items here. Uh alignment and tires. So,

items here. Uh alignment and tires. So,

what's cool here is that it's looking at a long-term trend of uh of input on the electronic power steering control module or electric power assist control module

to identify what kind if there's alignment error. Usually you want to see

alignment error. Usually you want to see somewhere below a half a degree in my opinion. I've seen them all over the

opinion. I've seen them all over the place, but uh see we don't have any data there. So as soon as you touch the

there. So as soon as you touch the brake, sometimes you got to move the wheel around just a little bit and then you can get that to update. You can see that we're at 3. We bought this car

brand new 3 months ago and uh after driving it a couple hundred miles, I checked that applied offset and this is after driving it down down a long stretch of road. It was at 1.4. four.

So, um, again, I knew an alignment was needed and indeed we put it on the alignment rack and dialed it in. And so,

if you're doing alignments, I would encourage you to look into doing the Tesla alignments, doing them properly.

The Model 3 and Y require ballasted. So,

you're going to put 150 pounds in each of the front seats. And then you're going to measure the ride height of the vehicle and move the seats four and a half to get the ride heights correct.

And then you're going to go through and do the uh do the alignment. you'll get

the best results with that. Um, and

additionally, we've had had some of the threes and Y's and even the U on the rear of the S's where um the alignment

the camber was too too far negative and we had to get some aftermarket components. We get those through uh our

components. We get those through uh our vendor we're using is um Unplugged Performance out in Los Angeles, which actually is right next door to SpaceX

and the Tesla design uh center out there. So, pretty cool stuff. So, here's

there. So, pretty cool stuff. So, here's

where you would do u you could clear the applied offset after you do your alignment and you're going to take it out for a drive. And then we also have what's called an offset drive test. And

this will allow you to actually run through a mode and it will prompt you to drive the car straight down the road for a period of time and it'll do a quick assessment of the offset. I believe

Tesla has this in place just to kind of run a a preliminary check before they before the technician is actually allowed to put it on the alignment rack.

If it gets a pass, I don't believe they will do an alignment. They'll they'll

just say everything's good. Um so just uh you know use that um knowledge as you can. And then down below that you have

can. And then down below that you have the tire uh reset. So this is a reset after reset the tire estimates. So tire

wear estimates. Um and then also whenever you do a rotation you're going to go in here and um set that up. And

also whenever you change tires, of course, uh you're going to basically want to set the different types if you're changing from a winter to a summer. Um and that's done in another

summer. Um and that's done in another panel. Um but this will let you do a

panel. Um but this will let you do a relearn on that. Uh all right. Uh we do have a steering panel. Um this is steering wheel control module. Uh so you can kind of check all your different

buttons. You can see the little there

buttons. You can see the little there some of the buttons there. I'm on the left wheel here. I'm pressing down on it. I'm going to press on the right

it. I'm going to press on the right wheel. Um,

wheel. Um, see the park lever. I'm pushing in the park button. So, so again, some

park button. So, so again, some diagnostic panels that you can use. And

then here's our brake uh tab. And you

can see there's some information here.

Turn our AC off again here. Uh, we've

got a brake stiffness check. And I'm

going to go ahead and just run this. And

this has what's called the IB booster.

And that's the Bosch iBooster. And it's

basically going to run through and it's going to check to see um if the pressures are correct and if there's any bleedoff leakage. So imagine if you had

bleedoff leakage. So imagine if you had you suspected you had air in the system.

I would run this test first and just let it run it its deal. Now I don't have a camera here, but I can see the brake pedal now being exercised. And it's

going to do a series of tests and it's going to give us a test report here in just a second. Okay.

And there we go. So it did pass. Um it

says that the measured stiffness is 63 bar. The minimum is 36 and the max is

bar. The minimum is 36 and the max is 80. They could check passed and it says

80. They could check passed and it says we have a 20 2.1 bar and the maximum is four. Okay. And then um below below that

four. Okay. And then um below below that is all the actual raw data raw test results. Okay.

results. Okay.

So good good info. And then also whenever you're bleeding, you know, you're still going to need to change brake fluid um on these vehicles. So,

you've got a brake bleed procedure that it'll help you with. Uh there's your electric parking brake service mode, so you can do the brake service um on a on the rear. And then you've got your brake

the rear. And then you've got your brake burnishing tab. And then down here,

burnishing tab. And then down here, we've got closure. So, all the windows, you can look and see um calibration on the different windows. If you're

changing out a window motor or doing any adjustments on the doors or what have you, um you're going to want to run the calibration again because it's doing the the pinch test uh pinch resistance so

that you know if somebody's got their finger in there, it's going to back off properly. So, you want to set all those

properly. So, you want to set all those up so that you can um perform that properly. And then down below that,

properly. And then down below that, we've got the airbags. And so, you can look at airbag information. It's giving

us a little hint. Tap on components to view So, I just hit the brake again. You see

that these things these systems are now being activated. So, we can see what's

being activated. So, we can see what's going on. So, everything looks good

going on. So, everything looks good there. And then there's some seat uh

there. And then there's some seat uh information uh and so on. So, that's

that's uh pretty much it for this service mode. Um I wanted to just touch

service mode. Um I wanted to just touch on one more thing here um back on our deck here. So, this is a short little

deck here. So, this is a short little recording. Um, whenever you're going to

recording. Um, whenever you're going to a supercharger, uh, you need to make sure that the car is navigating to that supercharger so it knows that it's it's going to be supercharged because there's

preconditioning that's going to take place. Got a short little clip here that

place. Got a short little clip here that I'm going to play and you're going to hear some audio because one of the ways that um it learn it if can scavenge heat or create heat

for the coolant loop to heat that battery up is that it can do uh what they call lossy control. And this this uh verbiage came from uh the professor

at Weber State University up in Utah, John Kelly. and uh he's got an awesome

John Kelly. and uh he's got an awesome video about the the entire U heat pump system. Uh so I encourage you to go

system. Uh so I encourage you to go check that out on on YouTube. Um the if you look over here, I've got another I've got a CAN tap on my vehicle to grab

two CAN channels. And you'll see that the front motor, which is actually an induction motor, is basically being used to create heat. And so what it's going

to do is going to basically just just basically try to lock that rotor and that that induction rotor. And as we're driving, the rotor is spinning through those magnetic fields. And you're going to hear this whining. And you may hear

the whining on the outside of the car.

But u customers may complain uh to you about that, but what's going on there is that it's scavenging heat. It's creating

heat and transferring it into the coolant. And you'll see that when we're

coolant. And you'll see that when we're accelerating here, we're we're we're using the rear traction motor for propulsion of the vehicle. Okay? And you

can see some torque numbers down here.

Um, and I'm just going to play this video. And you want to listen. You hear

video. And you want to listen. You hear

the whining.

You can see the front motor. It says 188 footbs, but it's not really being used to propel the vehicle.

And this other panel I just showed that's popped up. That's that has some some of that flow and temperatures.

But pretty cool uh pretty cool stuff.

All right. So, next we're going to go into toolbox and we're going to talk about that for just a second.

In the toolbox app, that is a required or that's a purchase. Um, and I I remember when we got access to this about two years ago, I I got it right

away and I wanted to explore and um and they again Tesla has really started to add a lot more uh features into this product here so that we could actually

perform uh more operations and we can now do remote stuff. So, I wanted to kind of show you what that's all about.

But before we do that, I'm going to just connect Toolbox to the car and I'm going to show you what happens to the panels inside the vehicle for the uh what you

get with Toolbox. So over here on the left um or on my this is I'm already logged into my account and I'm going to click on this vehicle connection

um here and right down here I'm just going to click on connect. All right.

And we are connected. So very very quick connection. Some of the earlier cars may

connection. Some of the earlier cars may be a little slower to connect.

And um and you you also need to make sure if you're if you're using a u you know you're using an RJ45 Ethernet port on your computer to

connect, you need to watch those activity lights. If they're not lit up,

activity lights. If they're not lit up, sometimes you got to get in the car and actually press on the brake. may need to put it into drive and then put it into park and uh put that wake wake that system up and then go make your

connection. But this this is a later

connection. But this this is a later model car hardware for car. Very very

quick to connect. So uh let's go back into the car here, John.

And we now see down at the bottom right we have CAN viewer. Okay. And you can see at the top of the screen it says uh uh service mode plus. And you can see

some of the signals that I've got up here um already selected. So I can clear all those out. This is the bus. This is

the Ethernet bus. And then we're going to reach into these other modules and take a look at some of the data here. Um

EPAS angle calibration applied offset.

So there we've got our our 0.5 degrees there. Um

there. Um we can add all those. So you can see the steering the torque on the steering wheel as as well. All right, but that's

that's kind of boring because if we go back here to our panel, if we go into the low voltage here, we now have an option that says CAN bus. Okay, gives us

a warning. It says the CAN bus

a warning. It says the CAN bus diagnostic panel is in beta. Uh but now here we're looking at the party bus in the center selected there. how many

errors are being seen and all the modules and uh whether they're online or not. Okay, we go to the vehicle bus here

not. Okay, we go to the vehicle bus here on the left and then we can also look at the chassis bus as well. Um so uh so this might help you with doing some

diagnostics on the vehicle. Maybe you've

got a harness that you're chasing down.

You want to start wiggling harnesses um and having somebody monitor this uh and so on. Um yeah. Uh so that is uh that's

so on. Um yeah. Uh so that is uh that's that's what we've got there. So I'm

going to basically exit service mode now and I'm going to demonstrate what you can do without actually being connected to the car.

So say that you've got a client that uh calls you and you want to um you want to basically access their car remotely. You're going

to come to this uh owner authorization request page here after you log into toolbox and you're going to request owner authorization and you have to enter their email. You have to have the

VIN and then you're going to give it a reason. You're going to ensure you're

reason. You're going to ensure you're not a robot and then you're going to send that send that out. I have two cars currently that um I've got access to. Uh

they expire after I believe a week and seven days. Um, and so I've got these

seven days. Um, and so I've got these two cars that I have access to. And the

first thing I want to do is go to garage. Okay.

garage. Okay.

And I already had this vehicle selected. So,

it's trying to connect to this car. And

this is mine. This is the one that's sitting next to us. But it's it's reaching out to Tesla's servers and then back into the car and pulling some data up. Okay. And one of the things that

up. Okay. And one of the things that it's pulling up here is uh we've got the VIN, we've got when it was the bill date, uh the mileage,

and then um I want to pay bring your attention to these three items right here. See where it says HVAC rail is on,

here. See where it says HVAC rail is on, which you usually see that on all the time. And but the accessory rails off

time. And but the accessory rails off and the drive rail is off. And the

reason this is important is if you wanted to get some of the other data parameters you will see that are missing down here, you may need to work with the client and and at the time you're

accessing this have them on the brake pedal and have the all the rails up and powered up. Okay. Um, and we'll get down

powered up. Okay. Um, and we'll get down to that data here in just a second.

Second thing to be aware of, and I just had a inquiry from a customer recently trying to figure out why he he has uh some some problems with um with the vehicle.

Um we looked in here and I saw it said supercharging access here and it said not allowed. All right. And that was a

not allowed. All right. And that was a red flag for me. And um you know, after a series of questioning with the customer, I found out this car was actually a salvage title vehicle. And

when they are salvaged title, Tesla takes them off the supercharging access until they go through a um a certification inspection and uh then

they they may put it back on uh available. So good information to be

available. So good information to be aware of. Um so if we come down here and

aware of. Um so if we come down here and we talked earlier about this electronic power assisted shearing. Uh so we have both the primary and secondary modules where we're looking for that angle

offset to determine if maybe there might be a problem with the alignment. We

don't have any data there. Right. So

what I'm going to do now I'm going to put a brake uh brake pedal depressor on the car.

Wake that stuff up.

And then I'm going to come over here. I'm going to click on CAN Explorer. And I'm going to go back

CAN Explorer. And I'm going to go back to garage. And it's going to refresh

to garage. And it's going to refresh data from the vehicle.

And we come down here and we see now all the rails are on. Okay. And so now when we come down to our power steering data, we can now see those data values. Okay.

All right. Uh also you can see all the different camera calibration um the the progress and the actual current pitches, pitch angles and so on. Uh a lot of high

voltage stuff, infotainment stuff and just tons of information that you can get remotely. Um and then a lot of these

get remotely. Um and then a lot of these service fix uh alerts here to take a look at. And if you click on one of

look at. And if you click on one of these, it's going to take you into the toolbox service information. and we can click through and start reading about

these uh articles. Uh so lots of lots of good data here. So we're going to quickly I know we're getting towards the end of this, but I wanted to show one more thing here. Over here we have

what's called Can Explorer. Okay.

And can explore is uh pretty cool. And I

don't I have to have a VIN up here. And

that is this VIN right here. So, as soon as I put that VIN in, it's going to look at it. By default, it pulls up the last

at it. By default, it pulls up the last two weeks, and it's showing what logs are available. And you can see that on

are available. And you can see that on the left side, a manual poll. I actually

requested logs uh prior to this this event. You can hit request logs to get

event. You can hit request logs to get all the latest data. And then it may take 30 minutes or so to get that information, but uh you can see that we do have some data here available. If we

go over to the left here where it says alerts, we can actually see all the warnings, warning alerts. Okay, you can see how

warning alerts. Okay, you can see how many times that alert has set 12 times.

There we have links to articles so you can do some uh research on it. Um and so on. Also, emergency speaker fail there.

on. Also, emergency speaker fail there.

Um collision warning event. So, if I was to click on this, which I just did, it's going to basically load up a panel down here and pull in a bunch of alerts,

alert data, payload to help us gain a little more perspective as to what uh what was happening with this vehicle.

Okay, so we can mouse over each of these and get uh some info about when the alert cleared. And so, this is showing us only

cleared. And so, this is showing us only when it cleared. doesn't show us when it actually set, but it gives us some information uh some data that might be

useful for us to analyze the problem further. And you can continue to add

further. And you can continue to add more and more. Right? So, I I'm clicking on that one down there. Uh let's see.

Watchdog reset. We'll let it load up. Uh

the next thing over here, and this probably deserves a deeper uh session to kind of go into exactly what you can do here, but now we have signals. Okay? And

so say that we wanted to look at a specific signal, we can search for one.

I'm just going to type in speed since that should be um should be pretty easy.

So say that say we had an ABS question or something. We want to pull up all the

or something. We want to pull up all the wheel speed sensors in history. So I'm

going to click on that first one there.

It's going to load it up into a panel.

And you'll see right there it's loading.

But say I wanted to put all four of these on this same panel. So the front front left, I got the front right. So if

I click on this, it's going to actually add a second panel below this. But if I want to just click and drag it over, I have options. I can put it on the stack

have options. I can put it on the stack it on the top, stack it on the bottom, or I can put it on the right axis. So

I'm going to basically put the left on the left axis, the right all the rights on the right axis. Okay? And those are going to

axis. Okay? And those are going to continue to load up. And in just a second, we're going to have all that data available to us. So, we have now

the front right, we have the rear. Okay. And we have them all. All

rear. Okay. And we have them all. All

right. So, we have them all. Um, we can scrub across here. You see, we have a lot of data. So, we can go ahead and kind of zoom in. Click and drag.

Click and drag again. Oops. There we go.

Click and drag.

and click and drag. Of course, this car doesn't have any problems, but here we can we can go through and look at a log in history and we can reference it with some time uh perhaps when the customer

was having some sort of problem or maybe when there was another event or something uh taking place. Um you can

you can actually uh take grab a PNG so you can download an image of this over here on the top. You can actually download all the plots at once and it's

basically just going to download that and then you can also just download all the CSV data. So you want to get all the all the data in a raw CSV file. Um

you can click download. It gives it a file name with the VIN number and all the the time and date stamp and let it download. Okay.

download. Okay.

All right. So um let's go back to our presentation deck there, Johnny. And uh

so as you can see there's some pretty powerful features here. We didn't go through all of them. Uh lot of really cool stuff. And so do we have any

cool stuff. And so do we have any questions that have uh really popped up that we need to address here, Johnny?

Yeah, Brandon wants to know if access to the garage and service mode plus are free or do they require a subscription?

No, that is a subscription. So you can get a short-term subscription or or an annual subscription for that. And I I believe the annual now is $3,000. It was

2000 when I first got into it, but you also had to buy service information at that time. And since then, they've made

that time. And since then, they've made the service info free and raised the price of uh the toolbox application, but in most cases, all you need is a RJ45

Ethernet cable. There are some earlier

Ethernet cable. There are some earlier cars where you need a special adapter, and there's one special group of uh vehicles where you need to have this media access controller. uh very

expensive uh interface device, but it's only a very small range of uh vehicles to get access to it. Okay. Um all right.

So, uh any other questions?

Yeah, Carla wants to know if accessing malfunction codes is only available via the toolbox or can you see that in service mode?

You can see this the malfunction codes in service mode. Uh so on the very first page that you go onto, you got service alerts. you can go through and look at

alerts. you can go through and look at what those alerts are and uh and pull those up. But in order for in order to

those up. But in order for in order to do anything remotely that we just talked about here, you have to have the paid uh subscription uh to Tesla. And you again, you can get a short term if you want to

just play with it, but um it it will require a lot of time, right? You're

going to need to figure out what what's normal, what's not normal. This is

really the point of this uh this video here is to help us get familiar with these systems because we need to learn what's normal and what to expect uh when

we get challenged with a uh with a problem. Okay. All right. Uh so there

problem. Okay. All right. Uh so there are a couple of resources here I want to share with you. Um we've got Weber State uh Professor John Kelly. I mentioned

that earlier. They have a training program. It's a nonredit system. Uh

program. It's a nonredit system. Uh

they've got some online training uh that are prerequisites for a week-long hands-on training and certification system. Uh we have Earthling Auto up in

system. Uh we have Earthling Auto up in uh San Francisco. Um that's Carolyn Cocolet's uh business up there and Jack Rose is now doing uh training in their

old shop since they moved to a new shop.

Uh Euroch up in Minnesota, we've got Seth Thorson.

uh he is uh doing a lot of training on the Tesla stuff and uh doing some really good exploration and of course we've got uh the diagnostic network. So I

encourage you to add those to your list of items and uh if we have any further questions uh we can throw them in the in the chat. Otherwise we've got about two

the chat. Otherwise we've got about two minutes and I want to thank you for attending this and uh please give me some feedback on this. I need to know

what worked, what didn't work for you, um whether the presentation was worthwhile. Um because I want to want to

worthwhile. Um because I want to want to try to do some more of this kind of work. Uh there's a lot to explore here

work. Uh there's a lot to explore here on on this particular car. And of

course, we've got other stuff that we can explore and share knowledge and information on, too. So, um any other questions there, Johnny coming in?

Yeah, Brandon also wants to know if uh he wanted to know how you set up the screen recording on the vehicle.

Uh, I have a special um I had my monitor uh modified and uh is I basically actually what I did I found a guy online

um he's back east and this is a second one of these monitors. So I have the original the center stack center screen.

I I just ordered a special one from him that he's modified and put an uh HDMI out on. Uh, but in order to get that

out on. Uh, but in order to get that HDMI out, I have to go to through a special converter box because it's an odd uh ratio uh odd dimensions and a lot

of the the uh uh screen recognition devices don't always pull that up. So, I

hope that answered your question. Uh,

anything else? No other questions? Okay.

Well, there will be also in the chat if you need a certificate of attendance, please put something in the chat saying, "Hey, I'd like a certificate." I will

email you a certificate uh um sometime in the near future, next couple days or so. Um but uh otherwise, thanks for

so. Um but uh otherwise, thanks for everything and uh we'll see you on the other side.
