2002... Interior lights and door locks cycle when driving, door unlocks after being lock and vehicle is parked. Checked for any codes in the MIC found ...tcm bus messages not received, pcm bus messages not received, ipm/fcm bus messages not received, improper power down detected. The BCM had driver power door lock circuit stuck. The icm/fcm had fog lamp relay circuit open. All the modules are seen on the bus, the bus voltage is .06-(-).06. Both both signals are open. CCD bus signals 6. DRB can communicate with all modules. I am looking at the MIC for possible failure at this point
