Possible Causes
- •Deviation from specification in engine tuning, air-fuel calibration, or gas pressure regulation
- •Fuel injection system (MCRS) fault
- •Charge air cooler leaks
- •Cooling system fault
- •PowerCommand 3.3 controller fault
- •Infrequent unit exercise
- •Starting system (24V battery bank) fault
- •Faulty spark plugs (multi-cylinder)
- •Gas regulator / air-fuel mixer malfunction
- •Ignition system failure (coils / module)
- •Catalytic converter restriction/failure
- •Turbocharger system failure
- •Fuel injection system (MCRS) failure
- •Charged air-cooled intake system fault
- •Cooling system failure
- •PowerCommand 3.3 controller issues
- •Spark plugs (multi-cylinder) failure
- •Gas regulator / air-fuel mixer failure
- •Ignition system (coils / module) failure
- •Catalytic converter failure
Suggested Actions
- 1Verify turbocharger boost pressure
- 2Verify exhaust backpressure
- 3Verify dynamic gas inlet pressure
- 4Perform firmware update
