Anyone with any insights, your input is greatly appreciated.
I have a 2015 MS P85DL AP1.0
Upgraded to MCU2 last fall.
When I picked up my car from SC, new issues were found that were not there before the upgrade. SC wanted to hours to diagnose.
I said there was nothing wrong when I brought vehicle in (except the eMMC black MCU1 screen) and that I don't want to pay for them to diagnose.
SC said the alerts/problems may clear on their own.
Still have the issues 12 months later.
ISSUES:
1. Intelligent battery sensor is not communicating with MCU2 (GTW-w026 ibs-Mia)
2. Heated seats have stopped working.
3. While driving, the vehicle thinks it is always in Neutral and that the Parking Brake should be on...(GTW-u014 Parking Brake Not On, Vehicle May Free Roll.)
My Partial Diagnosis:
Traced the ibs wiring to its MCU connector behind the MCU2 (not a lot of fun to get back there).
This connector is not connected and is just hanging back there....and worse, the new MCU2 doesn't have an open slot for it to plug in.
I see on the Tesla Service wiring/circuit diagrams that this unplugged connector in question also has the signal wire for the heated seats.
I can provide more details if needed.
Is there a different MCU2 that I should have gotten that has a placed to connect my dangling connector?
Thoughts?
