DESCRIPTION:
Diesel Oxidation Catalyst (DOC) efficiency fault.
MONITORED PARAMETER:
Exhaust temperature
TYPICAL ENABLING CONDITIONS:
Always on
MONITOR SEQUENCE:
None
EXECUTION FREQUENCY:
Continuous when enabling conditions met.
TYPICAL DURATION:
Two seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
Derate 25%
VERIFICATION:
Parked regen
NOTE: If any other codes are active, repair those first.
PROBABLE CAUSES:
1. Inspect all wiring & connections upstream of the ACM: DOC outlet temperature, ATD harness 10-pin connector, VIH 47-pin connector, and ACM 120-pin connector.
2. DOC outlet temperature sensor failure.
3. DOC inlet temperature sensor failure.
4. DPF outlet pressure sensor.
5. DPF inlet pressure sensor.
6. Wiring/connectors for sensors mentioned above.
7. Check for the DPF being plugged/failed.
8. Perform stationary regen.
