Lost Communication with Power Steering etc After Dead Battery and Multiple Jumps

Demonator · 06-22-2022, 11:45 AM

After my car’s battery mysteriously went dead, I jumped it a few times because the alternator wasn’t working. Got the alternator back on after replacing a terminal on the front fuse box and now the power steering is out, the driver’s window won’t work, lost communication with body control module, and other codes.

There is good power and ground to the module and all the wires are checked. i would appreciate any ideas. Thank you.

Does it start? If not, CAN related question, does your fuel level read zero?
