NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some motor control module (MCM) faults. The diagnostic service tool standard makes the distinction between the MCM and CPC diagnosing a fault. NOTE: If any battery voltage codes present, first those first. If code 625-9 active, fix that before proceeding as well. PROBABLE CAUSES:1. CPC recently programmed incorrectly.2. Another computer on the truck is the cause of the problems (ABS, Transmission, etc…).
