2015 Tahoe LT Body Control Module ?

[Gr8grass]

Hello all

I own a 2015 Tahoe LT with 120k on it.

Recently, after a dealer service, two TPS monitors are unreadable.

Also the distance markers for the rear backup camera system are not available.

The air conditioning system has become intermittent. The AC is serviced correctly,.

 

Since the vehicle is out of warranty, I took it to a qualified mechanic who found 80+ body codes when he plugged his scanner in.

The mechanic plugged in several of the codes to his AllData program and was directed to a TSB for chaffed wires at or near the BCM, 4 wires were found chaffed. He repaired them, however, the problems persist.

Any suggestions?

Thanks in advance
