NOTE: The troubleshooting solution is the same for any and all fault descriptions. POSSIBLE CAUSES:1. Faulty common powertrain controller.2. Needs software update. NOTE: Reprogram the CPC with the latest software release.

NOTE: A fault may set during common powertrain controller (CPC) module reprogramming. If a fault occurs while programming, clear the code and release the vehicle. NOTE: If there are battery related codes or 625-9 present, fix those first. PROBABLE CAUSES:1. If the CPC has been programmed recently, clear the codes, test drive, and release if it doesn’t come back.2. CPC has the incorrect programming.

POSSIBLE CAUSES:1. Diagnostic service tool connection to the CPC/MCM at a specific time within the first few seconds of ignition on, and remaining connected for over 10 minutes.2. Sending parameters to the CPC while connected to both the CPC and MCM and the diagnostic service tool remaining connected for over 10 minutes. NOTE: The only solution is to disconnect the diagnostic software and re-connect.
