Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3866 FMI 3 (CPC) Digital Input 4 04 – Failed High on Pin 4 Circuit of the Common Powertrain Controller #4 Connector

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 4 of the CPC4 #4 connector.
