Ran into an odd issue yesterday. Airbag light came on. Shortly after, tire pressure sensor blinked yellow then stayed on. Seat heaters no longer worked. No noise from turn signals, but they were working. No issue with engine/drivetrain. Battery good, main grounds good. Read the codes: GM K bus data transmission disturbed, KOMBI: Data-filing difference to central light module, RDC: k bus, timeout. Anyone have something similar happen to them? I turned off vehicle, let it sit and turned it on. It went back to normal. I read the codes, reset them and then disconnected and reconnected battery. No issues today. This issue has never occurred in the 7 years of ownership.
