Description: DPF Regen Inhibit MUX Switch Message Contains Data Error Indicator
Troubleshooting:
DESCRIPTION:
A communication error occurred on the CPC DPF inhibit switch.
MONITORED PARAMETER:
Diesel Particulate Filter (DPF) inhibit switch.
TYPICAL ENABLING CONDITIONS:
Key on, engine off.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None
VERIFICATION:
Cycle the key to power down, then cycle the key back on.
POSSIBLE CAUSES:
1. Common Powertrain Controller (CPC) needs reprogramming.
2. CPC needs proper configuration.
3. Faulty CPC.

Description: High Idle Regeneration (Aborted) – Low Exhaust Temperature
Troubleshooting:
NOTE: The fault indicates that the high idle regeneration (HIR) was aborted due to the diesel
oxidation catalyst (DOC) inlet temperature not reaching the minimum of 270 C (518 F) to
initiate dosing during an HIR. The CEL and MIL lamps will remain on until the fault is resolved
or a successful regeneration is completed.
POSSIBLE CAUSES:
1. Faulty DOC inlet temperature sensor.
2. Faulty Intake Throttle Valve (ITV).
3. Leaks in the exhaust system.
4. Faulty MCM.
5. Faulty exhaust rocker arm shaft.
6. Faulty solenoid.
7. Engine needs a regen.
8. Faulty cam frame housing.
