I purchased a 2021 model 3 with front damage. I replaced the Pyro fuse, SRS computer, seat belts and airbags. The radiator and shroud and many other parts. Last weekend I had everything working. How ever it stopped work soon after a software update try to install. It said it was unable to complete, however the car shows the software version is new and up to date.
HVP_w015 unable to charge service is required
CP_a016 Unable to charge
UI_a019 parking brake functions degraded
BMS_a179 vehicle may not restart
I unplugged the 12v battery, the first responder loop and the 12v penthouse connector in the back seat. Waited several hours. Plugged them back in (reverse order). It cleared the codes. The coolant pumps turn on (never really stop). The drivers side doors all work. The computer comes on. The passenger side doors/windows never reboot. The HV system doesn’t come online. The car will not shift. The car will not charge. I have repeated the process many times. Last weekend it worked but know it doesn’t. I have recharged the 12v battery contently. I bought a deep cycle full size battery which I also charge and hook the the 12v with jumper cables. I no longer believe it’s a 12v battery issue. The HV just will not engage. Not sure it the second computer is even on. The parking brake will not disengage. Towing mode is greyed out.
Any recommendations would be very welcomed.
