What This Code Means
Hardware errors in the injectors; Hardware errors in the ECM power stages; Incorrect injector energizing time at low idle; Incorrect pilot injection energizing time; Electric failure in the power stage of the glow plug; Undetected real electric failure of the glow plug; Electric failure in the power stage of glow plug; Electric failure of glow plug
Possible Causes
- •Overcurrent
- •Command collision
- •RAM error
- •Short circuit
- •Learned calibration values out of range
- •Faulty relay between ECU and Glow plug
- •Lack of an intelligent relay preventing detection of real glow plug electric failures
Suggested Actions
- 1Use pattern detection to identify specific errors
- 2Trigger appropriate substitute reaction
- 3Evaluate energizing time for injectors at low idle using Zero Fuel Calibration during Low Idle (ZFL) functionality
- 4Monitor learned calibration values
- 5Inspect the relay between ECU and Glow plug to determine if the failure is caused by the relay or the glow plug
- 6Ensure an intelligent relay is used to enable detection of real electric failures of the glow plug
