Cummins fault code 287 is documented on this DiagTechPro library page for Cummins ISM CM871 (2007-09) engines, where it flags a Sae J1939 Multiplexed Accelerator Pedal Or Lever Sensor System – Received Network Data In Error condition (PID P91, SPN 91, FMI 2/19, Red lamp). This 3-page PDF reproduces the manufacturer description, shop talk, component location and step-by-step troubleshooting so technicians can confirm and clear the code.
Cummins fault code 287 overview
Cummins defines this code as “SAE J1939 MULTIPLEXED ACCELERATOR PEDAL OR LEVER SENSOR SYSTEM – RECEIVED NETWORK DATA IN ERROR” on the SAE J1939 Multiplexed Accelerator Pedal or Lever Sensor. Normally, switches, accelerators, and other components are connected to the engine electronic control module (ECM) directly through individual wires. Multiplexing allows those same components to be hard wired to an original equipment manufacturer (OEM) VECU or transmission electronic control unit in the cab. Then component values and states from components (such as sensors, accelerators, and switches) can be transmitted from the OEM VECU to the Cummins engine ECM over the SAE J1939 datalink.
Shop talk notes: Verify the electronic control module (ECM) calibration is correct. If necessary, recalibrate the ECM. This fault can occur when the OEM VECU detects an error on the accelerator.
