Cummins ISB CM850 (2003-06) Fault Code: 1117 (Auto) 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). This fault is set active if the ECM battery supply voltage drops below + 6.2-VDC while the keyswitch is in the ON position. Make sure the ECM unswitched battery supply is coming directly from the battery and not the starter. If unswitched power is coming from...

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. This fault code can be caused by a failed or damaged injector causing continuous injection into the cylinder. Progressive cylinder damage may occur if the engine is operated for an extended period of time with this condition. If a failed injector is found to be the cause of this fault code, the cylinder liner and piston must be inspected for progressive damage. If an...
