Reason:SAE J1939 Multiplexed Accelerator Pedal or Lever Sensor System – Received Network Data In Error. The J1939 multiplexing controller has indicated a malfunction of the multiplexed accelerator pedal. Effect:Engine will only idle. Circuit Description:Normally, switches, accelerators, and other components are connected to the engine control module (ECM) directly through individual wires. Multiplexing allows those same components to be hard wired to an original equipment manufacturer (OEM) vehicle electronic control unit (VECU) or transmission electronic control unit (ECU) in the cab. Then component values and states from components such as sensors, accelerators, and switches can be transmitted from the OEM VECU...

Reason:Intake Manifold 1 Temperature Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at intake manifold air temperature circuit. Effect:Fan will stay ON if controlled by the engine control module (ECM). Circuit Description:The Engine Control Module (ECM) provides 5 volts to the intake manifold temperature signal circuit, and monitors the change in voltage caused by changes in the resistance of the sensor to determine the intake manifold temperature. When the intake air is cold, the sensor (or thermistor) resistance is high. The ECM signal voltage only pulls down a small amount through the sensor...

Reason:Auxiliary Pressure Sensor Input 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected on the original equipment manufacturer (OEM) pressure sensor circuit. Effect:None on performance Circuit Description:The original equipment manufacturer (OEM) has the option of wiring a pressure or temperature sensor input to the Cummins® engine control module (ECM). A specific calibration is then created to recognize this pressure or temperature sensor input. This fault code is activated when the pressure or temperature input from the OEM sensor exceeds the engine protection limit defined by the OEM. Depending on OEM requirements, an Engine Protection...

Reason:Intake Manifold 1 Temperature Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at intake manifold air temperature circuit. Effect:Fan will stay ON if controlled by the engine control module (ECM). Circuit Description:The Engine Control Module (ECM) provides 5 volts to the intake manifold temperature signal circuit, and monitors the change in voltage caused by changes in the resistance of the sensor to determine the intake manifold temperature. When the intake air is cold, the sensor (or thermistor) resistance is high. The ECM signal voltage only pulls down a small amount through the sensor...

Reason:Intake Manifold 1 Temperature – Data Valid But Above Normal Operational Range – Most Severe Level. Intake manifold air temperature signal indicates intake manifold air temperature above engine protection critical limit. Effect:Progressive power and/or speed derate increasing in severity from time of alert. If the Engine Protection Shutdown feature is enabled, the engine will shut down 30 seconds after the red STOP lamps starts flashing. Circuit Description:The Engine Control Module (ECM) provides 5 volts to the intake manifold temperature signal circuit, and monitors the change in voltage caused by changes in the resistance of the sensor to determine the intake...
