Tesla Model 3/Y Heated Steering Wheel Retrofit Installation
HTML-код
- Опубликовано: 2 янв 2024
- Before the beginning of 2021, the Tesla Model 3/Y did not have a heated steering wheel. This video covers the installation process for a heated steering wheel retrofit in all 3/Y's that didn't originally come with one.
I'd like to start with a massive thank you to JWardell and PyjamaSam on the discord for all of their work on the CANserver and Heated Steering Retrofit Control Board!
These are the items you'll need to purchase. The total cost will be around $700 USD:
- CANserver (Dual Bus OBDII): bit.ly/CANserver
- Model 3/Y OBDII Adapter (Can be found on Amazon, but note there are different connectors depending on your model year)
- Heated Steering Retrofit Control Board: bit.ly/HeatedSteeringBoard
- Aux Power Relay Board (Optional but Recommended): bit.ly/RelayBoard
- Tesla OEM Heated Wheel Part #1490214-00-B: bit.ly/SourcingHeatedWheel
These are the tools that I used:
- Terminal (Pin) Removal Tool Kit
- Automotive Trim Removal Kit
- External Torx (E-Torx) E10 Socket
- 10mm Hex Bit Socket
- Torque Wrench
- Normal 10mm Socket
- Socket Wrench Set W/ Adapters for the Aforementioned Different Sized Bits
- Torx T30,T25,T20,T9 Screwdriver Bits
- Thin Metal Tool / Screwdriver for Releasing Wheel Airbag
- Wire Stripper / Crimper
- Heat Shrink
- Electrical Tape
- Butt Splice Connectors
- 1/4" Ring Terminals
- 14 gauge Stranded Wire
- Soldering Supplies
Nice to Have on Hand:
- Headlamp
- Sharpie
- Magnetic Screw Tray
I'd encourage you to use Tesla's free service manual for reference when performing the standard procedures (12v shutoff, airbag removal, steering wheel torque, etc.) in this video. The free documentation is available at bit.ly/TeslaServiceManual. There are lots of videos on RUclips for some of this stuff, too.
When removing the original wheel, @SK360 on Discord pointed out that you should leave the center bolt still slightly screwed in while you are trying to wiggle the wheel off. Some wheels are harder to pull off than others and you might destroy your clock spring if you pull on the wheel too hard.
For more information specific to the retrofit itself, there is documentation on the Carnetics Shopify here: bit.ly/CarneticsDocs. You'll also find the link to the support server on Discord there.
Finally, I have a few notes on the control board configuration. Once you add the UI_frontLeftSeatHeat analysis item to the CANserver you'll likely need to click the restart button on the retrofit control board homepage before it picks up the new analysis item.
For the UI_frontLeftSeatHeat analysis item, I changed the starting bit to 48 instead of 42 so that the rear middle seat heater triggers the wheel instead of the driver's seat heater. The name of the analysis item needs to stay set to UI_frontLeftSeatHeat, though. Again, check out the Discord linked in the Carnetics Docs if you have any questions about configuration.
Here are the values I changed in the control board's heater settings page:
- Level 1: 35C
- Level 2: 45C
- Level 3: 55C
ErrMin: 420
ErrMax: 1024
Heater Check Settings: Disabled

Amazing video. Used this on how to unlock the connector we need to de-pin by the driver footwell.
Excellent, comprehensive video BTW
Excellent video
You are smart to say that because mine nearly broke my brand new cad
Sorry I’m not sure I understand. Can you give a little more context?
Why couldn't you just replace your original steering wheel control module without heating (mounted in the steering wheel) with a module that IS equipped with heating into your newly purchased heated steering wheel?
Why go through the process of installing the new CAM server and power supply.
A guy I knew plugged his heated model Y's steering wheel into his non-heated model 3, turned the heating on and it worked
None of the Model 3s built through at least the end of 2020 meet the power delivery requirements for the heated wheel.
In February 2021, Tesla started shipping a refreshed Model 3 that included a heated steering wheel for the first time. It was discovered that Tesla upgraded MOSFETs in VCLEFT to support the new wheel’s power requirements. The power wire for the wheel in the new cars is the same gauge, though, which is why it's possible to add the power relay board without any other wiring modifications.
I’m not certain, but there may have been a brief period where Tesla produced Model 3’s with a beefier VCLEFT and no heated wheel.
Community members have reported success without a power relay board, but they eventually experience one of the car’s e-fuses tripping during long drives or if the temperature settings are too high.
Even if you skip the power relay board, the car still doesn’t natively support the heating functionality for the new wheel. As far as I know, nothing will happen, and no new controls will appear in the car’s software if all you do is swap wheels.
Many people have tried, to no avail, getting Tesla Service to change their vehicle’s gateway configuration to enable heated wheel controls in the software. Some have gotten as far as getting the heated wheel icon to appear in the climate control menu, but it doesn’t actually do anything. That’s likely because Tesla knows the early Model 3’s can’t safely deliver enough power to the wheel. Therefore, you need a CAN Server to interface between the wheel and the car’s network. Since the CAN Server has no way to communicate with the wheel by itself, the wheel control board needs to be added too.
You should ask your friend for more details about when his car was built (a sticker inside the driver’s door shows the month/year) and if it was really just plug-and-play. I could’ve saved myself a Saturday and a few hundred bucks if it was that easy!
My friend's M3 was a 2021. You've just explained why it was so easy for him. Thanks for getting back to me. I've got a 2018 M3. I'm glad I saw your video when I did. It'll save me some headaches.
Thanks again,
Carl
Does the CAN Server have to stay connected or just to configure?
It needs to stay connected in order to let the wheel know that you turned on the back seat heater or whatever trigger you set. I believe there are physical buttons being developed to control the wheel heater, but I’m not sure if those will still require a CAN server or not.
I have access to reconfig the vehicle. Reconfigured my 2018 M3P for a PWS, Matrix headlights, and 2.0 center console.
Would I not be able to reconfig the vehicle for heated steering wheel and it populate in the UI to enable or is VC left different (bigger mosfets) to handle power draw?
Correct, VC Left has smaller fets on the older models. The wire running from VC Left to the wheel is the same gauge as the new models, though, which is makes the auxiliary power board a perfect solution.
There are a number of folks in the discord who have enabled the UI button but haven’t been able to get it to actually control anything as far as I know.

Any possibility of doing the CANBUS server and the rest of the hardware and having the CANBUS monitor for the heated steering wheel in the UI?
Seems like it would be possible if it's going by a heated seat trigger.... Why not trigger it with an actual heated steering wheel if the car is reconfiged for it.
@@davidalindseyIt seems like it would be possible, but I don’t think anyone’s been able to make that work yet. There are more insightful people on Discord that have explored this, though, and can probably give you a better answer.
@@carsonharvey3674Do you know when and how those guys got the UI button? I have an early 2021 Model 3 with the (at that time) new VCLeft, but initially no heated steering wheel. After swapping it for a heated one I should have all the hardware needed, but as far as I know enabling it on the software side requires to change secured gateway configs (114 and 115) which not even a tesla mechanic was able to activate on my car.
How did you get the 2.0 center console in a 2018, I’ve heard that the harness is different, really curious, also were the matrix headlights plug and play? Thanks!
Hello
Where do you find this board kit????thnks
Links and additional info in the description. carnetics.myshopify.com/en-us/products/heated-steering-retrofit-control-board
Ship to finland?
I'm not the seller for any of the electronics. It seems like the control board only ships to US/Canada, but you might be able to arrange something with the seller if you email or message on Discord.

Amazing video but way to much work, all you need to do is direct the blower to the steering wheel for 2 min and it will be 100 degrees
