Pinpoint Test C: The 4WD Indicators Do Not Operate Correctly/Do Not Operate/Flash

Normal Operation

The 4WD high indicator status is transmitted to the instrument cluster from the 4x4 module through the controller area network (CAN). A steady indicator displays whether the vehicle is in 4L or 4H, according to the driver selection. Depending on the type of failure, the indicator flashes at two minute intervals to indicate four-wheel drive system fault conditions.

Possible Causes

- instrument cluster
- 4WD system fault
- CAN circuits
- 4x4 module (PCM)
