Reason:SAE J1939 Multiplexing Remote Accelerator Pedal or Lever Position Sensor System – Received Network Data In Error. The OEM vehicle electronic control unit (VECU) detected a fault with the remote accelerator. Effect:Remote accelerator will not operate. 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...

Reason:Aftertreatment Fuel Pressure Sensor – Data Valid But Below Normal Operational Range – Least Severe Level. Low fuel pressure has been detected in the aftertreatment fuel system. Effect:None on performance Circuit Description:The aftertreatment fuel pressure sensor is used to monitor the fuel pressure into the aftertreatment system. The engine control module (ECM) supplies the aftertreatment fuel pressure sensor a 5 volt reference voltage. When the fuel pressure is low, the sensor signal voltage is low. When the fuel pressure is high, the sensor signal voltage is near the 5 volt reference voltage. The ECM monitors the aftertreatment fuel pressure signal...

Reason:Proprietary Data Link Error (OEM/Vehicle Data Link) – Abnormal Update Rate. The immobilizer anti-theft system will not operate properly. The engine could possibly not start. Effect:The immobilizer anti-theft system will not operate properly. The engine could possibly not start. Circuit Description:The immobilizer anti-theft device is connected to the primary engine electronic control module (ECM) through a J1939 data link network. Messages sent from the immobilizer anti-theft device are received by the Cummins® ECM and are used to control the anti-theft features. The Cummins® ECM and immobilizer anti theft device must be configured properly so that proper operation of the multiplexed...
