2023.12.1 Updated Service Menu and tools for legacy cars

[BrownOuttaSpec]

Overall release notes for 2023.12.1 are posted and there are other threads about the new features in the service menu for the newer cars (3/Y) but I wanted to show you what the few options are for the legacy model S/X (my specs in signature). We dont get all the cool stuff that the newer models have but we now have feature for coolant fill and purge, thermal test, door handle information, and a BMS reset button. The coolant tools were there in 2023.6 but the door handle and battery BMS reset seem to be new. I havent used any of these items but I like the idea that Tesla is slowly adding the ability for 3rd party people to do basic repair tasks on their vehicles.

Sweet! I need to replace 2 of my door handles. I guess I can just straight swap to gen 3, do ECU reset, and then calibrate them then?

Where are other legacy cars on the remote/auto window features? I see some of the 3/Y vehicles are getting some of those features back. My 2015 S allows the windows to vent remotely and that is all. I am missing close windows on lock.

What does the CCS Retrofit button do? Does it allow you to install the retrofit and update the configuration yourself? (Like can be done with HomeLink on the 3&Y?)

Hmm, CCS retro would have been useful on my last road trip, but the most useful thing still isn't available: A decent length cable for anyone towing!

No, you aren't missing that feature if you mean it's a bug or something is messed up. Legacy models don't have the "pinch sensor" on the windows so our cars will never have the remote window features other than vent since it is against the law in the US to have a remote closing window without that anti-pinch safety feature.

That is what I would assume. If you have the new part you can install it and then use that service function to inform the car it now has the feature.

So, did you try to press the 'Reset BMS' button?
I do wonder what it does

So... Who wants to be first to use the reset BMS button and record the before and after available miles and what it says / does????
(I would, but with a new battery I am chicken)

 

[zivac87]

It is bit different on model S but I guess Reset HVBMS is same function and new add-on with update, I still don't want to be guinea pig.

What is HVP abbreviation?

 

[davezforce]

really curious about the ccs retrofit button I would love to install it m self and be able to program the gateway with that tab

What the heck!! I have been doing the urban legend BMS reset ritual to reclaim some "lost" rated miles over past 12 months so this is timely. This BMW reset is now in service menu for 2020 S?? (wife has the car and is out of town so I can't quite check it!)

Why the nervousness about trying it, it obviously won't be in the service menu if its harmful?....

That certainly isn't true. I have seen someone say that they started a process, and it made their vehicle undriveable because they couldn't complete the process. (I think it was related to the coolant, or HVAC, systems.)

I tried the Reset SOC in my M3P while at 14% and the routine kept failing. It needed the contactors to be open but I dont hear them open as part of the routine to capture the open circuit voltage. Wonder if I need to manually open them myself before clicking run? And how?

 

[Dvdarb]

So, did anyone already tried this reset SoC button?

or Reset BMS

Ok I clicked it then said it can not run reset due to contacts needing to be open ....how do we do this then?

Same thing happened to me in my post above with pictures. I asked if HV contactors need to be manually pulled?
