Hey, I just read through this forum and am wondering if my issue can be fixed without having battery replaced by Tesla.
Car is 2014 Model S P85
Problem:
- MCU died after trying to replace the display (had leakage)
- Because MCU died, my 12V also died, as the car wouldn't go to sleep
- Since this moment I have the following errors(they kept changing but these I capture in an image):
- EPAS_d076_KFSDAS_TIMO
- GTW_W405-12VNotSupported
- GTW_W026_ibsMia
- BMS_u018_SOC_Imbalance_Limiting
- BMS_u008_limpMode
- BMS_w107_SW_Cell_Voltage_Sensor
- BMS_w007_SW_Module_Alarm_Broken
What I've tried:
- Charging the car. Charge port is red
- Checked fuses
- F92 Contactor Power
- F53 BMS Fuse
- F12 Drive Power
- F44 Charge Port
- Pulled BMS Fuse
- Reset BMS with Toolbox
- Clear BMS Alerts with Toolbox
- Powercycles
Extra information:
Ran HV-Autodiag: "Autodiag has detected an abnormal high brick impedance that may have contributed to loss of acceleration performance fromt he vehicle powertrain. CREATE A SESSION and mark Article 6669700 as a problem. Follow the "Steps to Fix" section within the article for the appoprate repair. The highest brick voltage delte detected was 3.2 V"
"Bad Brick voltage measurement from brick ID 45. The pack HWID is 41."
Before I buy another hour of Toolbox, could PROC_BMS_X_CLEAR_LATCH-BITS potentially fix this?
I refuse to go to Tesla and have my battery replaced for 12K just for them to easily fix the problem and reman my battery pack.
Car is in Veldhoven in the Netherlands.
Hopefully I provided more information to be pointed in the right direction.
