Cummins ISB CM850 (2003-06) Fault Code: 1144 PID: SID 5 SPN: 655 FMI: 7 Injector Solenoid Driver Cylinder 5 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder Number 5.
This fault code can be caused by a failed or damaged injector causing continuous injection. If an injector nozzle is fractured or stuck open, continuous fueling will occur in that cylinder. If this condition occurs, an audible engine knock will be present, and the engine may stall and not start. In addition, low fuel rail pressure and excessive exhaust smoke will be present during cranking conditions. If a failed injector is found to be the cause of this fault code, progressive damage to the combustion chamber may have occurred.
1)A stuck open injector nozzle has been detected. Replace the fuel injector.
Cummins ISB CM850 (2003-06) Fault Code: 1143 PID: SID 4 SPN: 654 FMI: 7 Injector Solenoid Driver Cylinder 4 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 4.
Cummins ISB CM850 (2003-06) Fault Code: 1142 PID: SID 3 SPN: 653 FMI: 7 Injector Solenoid Driver Cylinder 3 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 3.
Cummins ISB CM850 (2003-06) Fault Code: 1141 PID: SID 2 SPN: 652 FMI: 7 Injector Solenoid Driver Cylinder 2 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 2.
Cummins ISB CM850 (2003-06) Fault Code: 1139 PID: SID 1 SPN: 651 FMI: 7 Injector Solenoid Driver Cylinder 1 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 1.
Cummins ISB CM850 (2003-06) Fault Code: 1119 PID: 110 SPN: 110 FMI: 0 Engine Coolant Temperature – Data Valid But Above Normal Operating Range – Moderately Severe Level. Engine coolant temperature signal indicates engine coolant temperature is above engine protection warning limit.
Cummins ISB CM850 (2003-06) Fault Code: 1117 (Marine) PID: SID 251 SPN: 627 FMI: 2 Power Lost without Ignition Off – Data Erratic, Intermittent, or Incorrect. Supply voltage to the ECM fell below +6.2-VDC momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF).
