Cummins ISB CM850 (2003-06) Fault Code: 151 (Marine) PID: 110 SPN: 110 FMI: 0 Engine Coolant Temperature – Data Valid but Above Normal Operational Range – Most Severe Level. Engine coolant temperature signal indicates engine coolant temperature above engine protection critical limit.
This fault code indicates that coolant temperature has exceeded the engine protection limits for high coolant temperature.
Possible repairs:
1)Refer to the Engine Coolant Temperature Above Normal symptom troubleshooting tree in Troubleshooting and Repair Manual, ISB (Common Rail Fuel System) Series Engine, Bulletin 4021272 .
