Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2791 FMI 9 (MCM) Smart Remote Actuator 3 (EGR), No Communication
Posted by PerDiezel Solutions on
DESCRIPTION:The fault code sets when the motor control module (MCM) does not receive a message from the exhaust gas recirculation (EGR) valve actuator. MONITORED PARAMETER:MCM communication from the EGR valve actuator. TYPICAL ENABLING CONDITIONS:Ignition on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Ignition on PROBABLE CAUSES:1. If any voltage codes exist, fix those first.2. EGR valve actuator pull rod.3. EGR actuator.4. EGR valve.5. Wiring between the EGR actuator harness and the ECM.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2797 FMI 3 (MCM) Fuel Injector Needle Control Valve for Cylinder 1,2,3 Shorted to Battery Power
Posted by PerDiezel Solutions on
DESCRIPTION:Injector needle control valve cylinder 1, 2, 3 shorted to battery. MONITORED PARAMETER:Injector needle control valve cylinder 1, 2, 3. TYPICAL ENABLING CONDITIONS:Engine RPM = Idle or higher. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. Short to power between front fuel injector harness (14-pin connector) and the ECM (120-pin connector).2. Under valve cover fuel injector harness.
