Hi Everyone, I'm facing a weird issue with the 2015 S RWD, which has 108k miles; the main battery was dead because the car was parked for a long time and had to replace the LV 12V battery (new from Tesla).
the HV battery charged until 99%, tried to put the car into D or R and I received the warnings
The unexpected thing was when I unplugged the battery sensor, I could put the car in drive, but I received a warning message for GTW-w026 for sure because the sensor but the car was driveable, and it died in a couple of hours.
From my understanding, something is preventing the HV battery from charging the 12v LV battery.
FYI:
Is it a DC-DC issue? or HV battery pack issue? Do you have any recommendations on what it is?

FYI:
- Heat and cooling and climate control work as they should be
- The car has the DC-DC Converter - 2nd Generation
Is it a DC-DC issue? or HV battery pack issue? Do you have any recommendations on what it is?
