Detroit DD16 GHG14 (2014-16) Fault Code: SPN 4814 FMI 3 (MCM) Water Pump Circuit Failed High
Posted by PerDiezel Solutions on
DESCRIPTION:Water pump circuit short to battery. MONITORED PARAMETER:Water pump solenoid PWM11. TYPICAL ENABLING CONDITIONS:Enabled when engine coolant above 71°C (160°F). MONITOR SEQUENCE:Continuous EXECUTION FREQUENCY:Continuous TYPICAL DURATION:None DASH LAMPS:CEL ENGINE REACTION:None VERIFICATION:1. Engine running.2. Coolant above 71°C (160°F). PROBABLE CAUSES:1. Water pump failure.2. Fan, pulley, and drive belts.3. Water pump harness connector.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 5016 FMI 3 (ACM) High Side Digital Output 4 Circuit Failed High
Posted by PerDiezel Solutions on
DESCRIPTION:High side digital output circuit shorted to power. MONITORED PARAMETER:High sided digital output. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 Seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Key Cycle NOTE: The supply voltage circuit is networked internal of the Aftertreatment Control Module (ACM). This circuit supplies voltage to the Coolant Valve, DEF Post Run indicator (if equipped), and the Inlet NOx sensor. A short to power on any one of those circuits will set this fault code. PROBABLE CAUSES:1. Coolant valve connector/harness.2. Failed ACM (Aftertreament Control Module).
