Cummins ISB CM850 (2003-06) Fault Code: 2195 PID: SID 51 SPN: 703 FMI: 14 Auxiliary Equipment Sensor Input Engine Protection Critical – Special Instructions. OEM switch signal on the OEM harness indicates engine protection condition.
Verify the engine control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe? Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
Verify with the driver the engine operating condition when the fault occurs. Depending on the engine speed and load, the OEM switch can detect a condition that falls below or exceeds the engine protection limit. Refer to the OEM service manual for more information.
1)Replace the OEM sensor.
Cummins ISB CM850 (2003-06) Fault Code: 2186 PID: SID 232 SPN: FMI: 4 Sensor Supply Voltage 4 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at +5 VDC sensor supply circuit to the accelerator pedal position sensor.
Cummins ISB CM850 (2003-06) Fault Code: 2185 PID: SID 232 SPN: FMI: 3 Sensor Supply Voltage 4 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at +5 volt sensor supply circuit to the accelerator pedal position sensor.
Cummins ISB CM850 (2003-06) Fault Code: 2183 PID: SID 28 SPN: 1072 FMI: 4 Engine Brake Actuator Driver 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at the engine brake solenoid number 1 signal circuit.
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.
Cummins ISB CM850 (2003-06) Fault Code: 1911 PID: 157 SPN: 157 FMI: 0 Injector Metering Rail Number 1 Pressure – Data Valid But Above Normal Operating Range – Most Severe Level. Fuel pressure signal indicates that fuel pressure has exceeded the maximum limit for the given engine rating.
Cummins ISB CM850 (2003-06) Fault Code: 1892 PID: 84 SPN: 84 FMI: 1 Wheel-Based Vehicle Speed ? Data Valid but Below Normal Operational Range ? Moderately Severe Level. The ECM lost the vehicle speed signal.
