CODE: 287

LAMP: Red

REASON: The OEM vehicle electronic control unit (VECU) detected a fault with its throttle pedal.

EFFECT: The engine will only idle.

ACTION: Refer to the OEM troubleshooting and repair manual. Troubleshoot the accelerator pedal connected to the OEM supplied vehicle electronic control unit (VECU).

CODE: 288

LAMP: Red

REASON: The OEM vehicle electronic control unit (VECU) detected a fault with its remote throttle.

EFFECT: The engine will NOT respond to the remote throttle.

ACTION: Refer to the OEM Troubleshooting and Repair Manual. Troubleshoot the remote throttle pedal connected to the OEM supplied vehicle electronic control unit (VECU).

CODE: 295

LAMP: Yellow

REASON: An error in the ambient air pressure sensor signal was detected by the ECM.

EFFECT: Engine is derated to no-air setting.

ACTION: Verify ambient air pressure value is from 25.0 in Hg to 30.5 in Hg using INSITE™. Replace ambient air pressure sensor if necessary.

CODE: 299

LAMP: Yellow

REASON: The engine was shut down by a device other than the keyswitch before the proper engine cool down resulting in a filtered load factor above the maximum shutdown threshold.

EFFECT: No action taken by the ECM.

ACTION: 

CODE: 415

LAMP: Red

REASON: Oil pressure signal indicates oil pressure below the very low oil pressure engine protection limit.

EFFECT: Progressive power derate with increasing time after alert. If engine protection shutdown feature is enabled, engine will shut down 30 seconds after the red lamp starts flashing.

ACTION: Refer to the Low Oil Pressure symptom troubleshooting procedure in the ISM/QSM11 Series Engines Troubleshooting and Repair Manual, Bulletin No. 3666322-00.

CODE: 418

LAMP: Maintenance

REASON: Water has been detected in the fuel filter.

EFFECT: Possible white smoke, loss of power, or hard starting.

ACTION: Drain water from fuel filter. Refer to the Water in Fuel symptom troubleshooting procedure in the ISM/QSM11 Series Engines Troubleshooting and Repair Manual, Bulletin No. 3666322-00, if fault reoccurs frequently.

CODE: 419

LAMP: Yellow

REASON: An error in the intake manifold pressure sensor signal was detected by the ECM.

EFFECT: Engine is derated to no-air setting.

ACTION: Verify intake manifold pressure value is from -2.5 in Hg to 2.5 in Hg using INSITE™. Replace intake manifold pressure/temperature sensor if necessary.

CODE: 435

LAMP: Yellow

REASON: An error in the oil pressure sensor signal was detected by the ECM.

EFFECT: None on performance. No engine protection for oil pressure.

ACTION: Verify oil pressure valve is from -1.5 psi to 4.0 psi when the engine is stopped using INSITE™. Replace oil pressure/temperature sensor if necessary.

CODE: 471

LAMP: Yellow

REASON: Low crankcase oil level was detected by the ECM.

EFFECT: None on performance. Centinel™ system is deactivated.

ACTION: 

CODE: 595

LAMP: Yellow

REASON: Turbocharger overspeed protection fault.

EFFECT: The engine will run derated.

ACTION: Refer to the High Turbocharger Speed symptom troubleshooting procedure in the ISM/QSM11 Series Engines Troubleshooting and Repair Manual, Bulletin No. 3666322-00.

CODE: 611

LAMP: None

REASON: Engine shutdown by operator before the proper engine cool down, resulting in filtered load factor above maximum shutdown threshold.

EFFECT: No action taken by the ECM.

ACTION: Refer to the Hot Shutdown symptom troubleshooting procedures.

CODE: 775

LAMP: Maintenance

REASON: A slow leak has been detected in the air system.

EFFECT: None on performance.

ACTION: Check the vehicle air system for leaks. Refer to Section 012-019 in the ISM/QSM11 Series Engines Troubleshooting and Repair Manual, Bulletin No. 3666322-00.

CODE: 776

LAMP: Yellow

REASON: A fast leak has been detected in the air system.

CODE: 951

LAMP: None

REASON: A power imbalance between cylinders was detected by the ECM.

EFFECT: Engine can possibly have rough idle or misfire.

ACTION: Check fuel quality. Check for air being ingested by the fuel. It is normal to have an inactive Fault Code 951 after a service procedure introduced air into the fuel system, such as a filter change. Perform Cylinder Performance Test to determine if a particular cylinder or cylinders are high or low on power. Refer to Procedure 014-008 Cylinder Performance Test in the ISM/QSM11 Series Engines Troubleshooting and Repair Manual, Bulletin No. 3666322-00.
