Detroit Diesel

NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some motor control module (MCM) faults. NOTE: If ECM has been programmed recentely, check programming to ensure it is correct. NOTE: Otherwise, fix the open circuit on pin 2 of the CPC4 #4 connector. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3870 FMI 3 (CPC) Digital Input 4 02 – Failed High on Pin 2 Circuit of the Common Powertrain Controller # 4 Connector Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3869 FMI 4 (CPC) Digital Input 4 01 – Indicated by a Short to Ground on...
