Detroit DD16 EPA10 (2010-13) Fault Code: SPN 5016 FMI 3 (ACM) Coolant Valve Supply Voltage Failed High
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. MIL
2.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, Purge-in-process 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 (Aftertreatment Control Module).
