Cummins ISB CM850 (2003-06) Fault Code: 415 (Switch) PID: 100 SPN: 100 FMI: 11 Engine Oil Rifle Pressure – Data Valid but Below Normal Operational Range – Most Severe Level. Oil pressure signal indicates oil pressure is below the engine protection critical limit.
Possible causes:
1)Low oil pressure
2)Incorrect oil level
3)Damaged oil pressure switch
4)Engine harness shorted to ground.
Possible repairs:
1)Replace the oil pressure switch.
2)Repair or replace the engine harness.
3)Replace the ECM.
