Test C: The 4X4 Indicator Does Not Operate Correctly/Does Not Operate

Pinpoint Test C: The 4X4 Indicator Does Not Operate Correctly/Does Not Operate
Refer to Vehicle/Diagrams, Four-Wheel Drive System for schematic and connector information.

Normal Operation
The four wheel drive (4WD) system status is transmitted to the instrument cluster (IC) from the 4X4 control module through the high-speed controller area network (HS-CAN) to the powertrain malfunction indicator. A steady indicator displays if the vehicle is in all wheel drive (AWD) LOCKED mode, according to the driver selection. A 4WD system fault condition will illuminate the powertrain malfunction indicator. The powertrain malfunction indicator includes other general powertrain system failures. For information about HS-CAN, refer to Information Bus (Multiplex Communications Network).

This pinpoint test is intended to diagnose the following:
^ IC
^ 4WD system fault
^ HS-CAN circuits
^ 4X4 control module
