Pinpoint Test 7: the Instrument Cluster 4X4 Low and 4X4 Indicators Do Not Operate Correctly/Do Not Operate

TRANSFER CASE ELECTRONIC SHIFT PINPOINT TEST 7: THE INSTRUMENT CLUSTER 4X4 LOW AND 4X4 INDICATORS DO NOT OPERATE CORRECTLY/DO NOT OPERATE

Normal Operation
The 4x4 LOW and 4x4 indicator status is transmitted to the instrument cluster from the 4WD control module through the controller area network (CAN), circuits (WH/BU) and (WH). A steady indicator displays whether the vehicle is in 4x4 LOW or 4x4 HIGH mode, according to the driver selection. Flashing 4x4 and 4x4 LOW indicators is an indication that the instrument cluster has lost communication with the 4WD control module.

Possible Causes
- 4WD system fault.
- CAN circuits:
^ (W/L).
^ (W).
- Instrument cluster
- 4WD control module
