Exhaust shop welded on my car without isolating the battery, and caused a few issues.
I replaced the SRS module and ABS module already. They both accepted the new programming, but I'm still showing comms faults on the ABS module. The BCM should control the CAN comms on the system, so it's the next step in repairing this. Unfortunately, I do not have the equipment to flash it myself, so I'm troubleshooting through proxy.
The car has 2 BCM's, the main one is located behind the passenger lower cowl trim panel, and BCM-B is located in the trunk on the passenger side behind the side trim panel.
