Pinpoint Test J: The 4X4 Indicators Do Not Operate Correctly/Do Not Operate
Refer to Vehicle/Diagrams, Four-Wheel Drive (4WD) System for schematic and connector information.

Normal Operation
The 4X4 HIGH indicator status is transmitted to the instrument cluster (IC) from the 4X4 control module through the high-speed controller area network (HS-CAN). A steady indicator displays whether the vehicle is in 4X4 LOW or 4X4 HIGH, according to the driver selection. A four wheel drive (4WD) system fault will cause the powertrain malfunction indicator to illuminate when a 4WD system fault condition has been detected. This light also indicates other general powertrain failures.

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