2021 heated steering wheel Discussion thread
- Thread starter 808BOB
- Start date
That would be a pretty useful test!
I’d say it’s almost certain the wheel won’t heat when attached to the MY, but only because it won’t have the option enabled.
That blue plug appears to have a label that says “THERM” (thermal?) on it
OR... the option is only not enabled because there's no heated wheel hardware.
So those are the two possibilities:
- When the vehicle has the heated wheel hardware, the software detects it and displays the UI
- The software displays the UI due to an arbitrary flag that someone had to set for the vehicle
If we were betting a dollar, my bet would be that swapping wheels will work without any intervention by Tesla.
Given Tesla's stance on people installing their own garage door opener, I'd imagine it is locked in software to discourage us from electrocuting ourselves. That also assumes that the wiring in the column is compatible.That would be a pretty useful test!

That wire plugs into my right scrollwheel.

I’m convinced it’s a flag for the simple reason that SR+ cars are being delivered without the heating activated, and LR are. I would think they are both being shipped with the same wheel hardware at this point.
This would suggest to me that SR+ will get the option to pay to unlock it at some point, like rear heated seats.
Being able to unlock would mean Tesla, or a Tesla system, telling the car that it has that feature (after it has been purchased).
There may be some kind of communication between the steering wheel controller (in the wheel) and the car to advertise that it has the capability to, as a failsafe.
So could it be that it's just the harness that is needed for those with the newer steering wheel? Was that the reason for the delayed and random introduction, a shortage of this harness.
Always worth a reboot as well after any change, it activated those who installed the under car pedestrian warning speaker.

If you don't have the extra blue connector (i.e. heated wheel harness) then I would presume you don't have the heating element in the wheel, or the modified steering wheel controller either.
Sadly I think it is wishful thinking that people with LRs and Ps already delivered with the "new style" steering wheel are just waiting for Tesla to unlock it for them. MIC and latest Fremont M3s are arriving with the heated wheel already activated, and people are upgrading to the current version (2021.4.x) without losing heated wheel functionality.
That's just my opinion though, it is possible I guess there was a crossover point of parts. I would assume the steering wheel assembly is fitted to the car as a one-piece thing (i.e. embedded harness, controller, etc), rather than assembled in the factory.

Id open mine up, but Im afraid of letting the bag off somehow with my stupidity. LOL.
Just disconnect the battery if you're worried. The wheel itself takes less than a minute to open.

The battery under the rear seat, correct? Then use something to stick in the little holes, and pop the bag off, correct? From there, unbolt the wheel, and then look for what? Noob here to this stuff.
What year and is yours? Im a 2021 December build, so hoping for the wheel at some point. My SA told me mine does not have the wheel though, so... kind of gave up.
I believe that the air bag is part of the 12v system, so you'd want to disconnect the 12v battery in the frunk. Please double check this, though.
I'd err on the safe side and disconnect both batteries.
I'm a 12/20 build (awd-lr)as well. You need to disconnect the 12 under the frunk, per Tesla model 3 guide. I used an Allen wrench to pop the airbag off. The spring wires are an inch or two in, you have to push them in and towards the windshield. I was pushing straight in and the bottom latch wasn't releasing.

I would consider take a steering wheel off major surgery, but ok.Now we're resorting to taking our cars apart out of frustration over the cold steering wheel?
Just received 2021 Model 3 LR AWD with VIN 923xxx - heated steering is there. I'm so happy. Just another data point.
