NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If any battery voltage codes present, first those first. If code 625-9 active, fix that before proceding as well. PROBABLE CAUSES:1. CPC recently programmed incorrectly.2. Another computer on the truck is the cause of the problems (ABS, Transmission, etc…).

NOTE: The common powertrain controller (CPC) may have the same SPN as some motor control module (MCM) faults. The diagnostic service too makes the distinction between the MCM and CPC when diagnosing a fault. NOTE: This diagnostic is typically MCM engine hours data higher than expected. This fault usually occurs after reprogramming the CPC or MCM. The internal clocks of the CPC or MCM do not match. After reprogramming either module, all fault codes must be cleared. NOTE: This error usually occurs after an improper ECM programming. ECM must be programmed correctly, most often the internal clocks don’t match.

NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some motor control module (MCM) faults. The diagnostic service tool, 7.08 SP2 makes the distinction between the MCM and CPC when diagnosing a fault. NOTE: This diagnostic is typically MCM engine hours data increasing at an implausible rate. This fault usually occurs after reprogramming the CPC or MCM. The internal clocks of the CPC or MCM do not match. After reprogramming either module, all fault codes must be cleared. NOTE: This error usually occurs after an improper ECM programming. ECM must be programmed correctly, most often the...
