If the OEM vehicle electronic control unit detects an error with the accelerator pedal sensor, it transmits an error message to the ECM. This fault code is set active when the ECM receives an accelerator pedal sensor error message from the vehicle electronic control unit over the SAE J1939 data link.
Cummins ISX CM870 (2003-06) Fault Code: 286 PID: S231 SPN: 639 FMI: 13/13 The ECM expected information from a multiplexed device but only received a portion of the necessary information.
Cummins ISX CM870 (2003-06) Fault Code: 285 PID: S231 SPN: 639 FMI: 9/9 The ECM expected information from a multiplexed device but did not receive it soon enough or did not receive it at all.
Cummins ISX CM870 (2003-06) Fault Code: 284 PID: S221 SPN: 1043 FMI: 4/4 Engine Speed Sensor Supply Voltage Circuit – shorted low. Incorrect voltage detected on the ECM voltage supply line to the engine speed sensor.
Cummins ISX CM870 (2003-06) Fault Code: 265 PID: P174 SPN: 174 FMI: 4/4 Engine Fuel Temperature Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at engine fuel temperature circuit.
Cummins ISX CM870 (2003-06) Fault Code: 263 PID: P174 SPN: 174 FMI: 3/3 Engine Fuel Temperature Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at engine fuel temperature circuit.
Cummins ISX CM870 (2003-06) Fault Code: 259 PID: S017 SPN: 632 FMI: 7/7 The ECM detected that the fuel shutoff valve is stuck open mechanically or leaking.
