Detroit DD15 EPA10 (2010-13) Fault Code: SPN 3510 FMI 4 (ACM) Aftertreatment Control Module 2 Sensor Supply 2 Short to Ground
DESCRIPTION:
5V sensor supply bank 2 circuit failed low.
MONITORED PARAMETER:
Motor Control Module (MCM) 5V internal power supply.
TYPICAL ENABLING CONDITIONS:
Always enabled
MONITOR SEQUENCE:
None
EXECUTION FREQUENCY:
Always enabled
TYPICAL DURATION:
Two seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
None
VERIFICATION:
Engine Idle (1 minute).
NOTE: Disconnect one sensor at a time.
PROBABLE CAUSES:
When code goes inactive, that is the sensor that has failed:
1. Fuel line pressure sensor.
2. Fuel compensation pressure sensor.
3. Engine oil pressure sensor.
4. Inlet manifold pressure/temperature sensor.
5. DPF inlet pressure sensor.
6. DPF outlet pressure sensor.
7. Intake throttle valve.
8. Camshaft position sensor.
NOTE: If none go inactive, disconnect the 31-pin connector on left side of the engine. If code goes inactive, replace the DPF pressure sensor.
NOTE: If you disconnect the 120-pin ECM connection and the code is still active, replace the MCM.
