Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2646 FMI 4 (CPC) Digital Output 4 02 – Indicated By a Short to Ground on Pin 02 Circuit of the Common Powertrain Controller #4 Connector
Posted by PerDiezel Solutions on
NOTE: The powertrain controller (CPC) digital outputs have the same SPN as some motor control (MCM) faults. NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: Short to power on the pin 02 circuit of the CPC4 #4 connector or improper programming in the ECM.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2791 FMI 0 (MCM) High Load Operation in High Ambient Temperatures
Posted by PerDiezel Solutions on
NOTE: High load operation in high ambient temperatures. No action is necessary; this is a “silent” fault where the fan will be turned on. NOTE: This fault is a concern only if the fan-on times are excessive but coolant temperatures are in the normal operating range. PROBABLE CAUSES:1. If 110-0 is active, repair this first.2. Check for EGR exhaust leaks at the EGR valve actuator.3. Remove the actuator cooler lines and fittings, check for kinks/plugs or leaks.4. EGR valve actuator failure.
