Cummins ISB CM850 (2003-06) Fault Code: 195 (3 wires) PID: 111 SPN: 111 FMI: 3 Coolant Level Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at engine coolant level circuit. Possible causes: 1)Open return circuit in the engine harness, connectors, or sensor2)Signal circuit shorted to sensor supply or battery voltage3)Sensor supply circuit shorted to battery voltage. Possible repairs: 1)1)Replace the engine coolant level sensor.2)Repair or replace the OEM harness.

Cummins ISB CM850 (2003-06) Fault Code: 196 (2 wires) PID: 111 SPN: 111 FMI: 4 Coolant Level Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the engine coolant level circuit. Possible causes: 1)Signal circuit shorted to ground or return in the harness, sensor or connectors. Possible repairs: 1)Replace the engine coolant level sensor.2)Repair or replace the OEM harness.3)Replace the ECM.

Cummins ISB CM850 (2003-06) Fault Code: 196 (3 wires) PID: 111 SPN: 111 FMI: 4 Coolant Level Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at engine coolant level circuit. Possible causes: 1)Open SIGNAL circuit in the engine harness, connectors, or sensor2)Signal circuit shorted to ground in the engine harness, connector, or sensor3)Damaged sensor. Possible repairs: 1)Replace the engine coolant level sensor.2)Repair or replace the OEM harness.3)Replace the ECM.

Cummins ISB CM850 (2003-06) Fault Code: 197 PID: 111 SPN: 111 FMI: 1 Coolant Level – Data Valid but Below Normal Operational Range – Moderately Severe Level. Low engine coolant level detected. This fault code goes active when the coolant level inside the radiator top tank or surge tank drops below the sensor level. Fill the top tank with coolant. Possible repairs: 1)Add coolant to the engine.

Cummins ISB CM850 (2003-06) Fault Code: 1992 PID: SPN: 190 FMI: 0 Engine Crankshaft Speed/Position – Data Valid but Above Normal Operational Range – Moderately Severe Level. Engine crankshaft speed/position SIGNAL indicates engine speed above engine protection limit. This fault code is only applicable to engines powering generator sets. Possible causes: 1)External fuel sources drawn into the intake air passage2)Reverse powering (motoring) of the engine3)Tampering of the engine crankshaft speed/position and engine camshaft speed/position sensors. Inspect the intake manifold for sources of flammable vapors. Check the turbocharger seals to verify that there are no oil leaks. Inspect the engine crankshaft...
