U1418

U1418-IMPLAUSIBLE RIGHT WHEEL DISTANCE SIGNAL RECEIVED





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

Theory of Operation

The ABS module sends an implausible distance signal over the CAN C Bus circuit to the PCM.

- When Monitored:
Ignition on.

- Set Condition:
The Powertrain Control Module (PCM) receives an implausible signal over the CAN C circuit from the ABS module. The circuit is continuously monitored. One trip fault.





WARNING: On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.
