Test H: The Instrument Cluster 4X4 and Low Range Indicators Do Not Operate Correctly/Do Not Operate

Pinpoint Test H: The Instrument Cluster 4X4 And Low Range Indicators Do Not Operate Correctly/Do Not Operate

Normal Operation

The 4X4 and Low Range indicator status is transmitted to the instrument cluster via independent hardwired ground paths from the 4X4 control module through circuits 975 (BN/YE) and 210 (LB). A steady indicator is displayed whether the vehicle is in 4H or 4L according to the driver selection. Indicators do not flash under any circumstances. When the vehicle is in 4L the 4X4 and Low Range indicator circuits are displayed. When the 4X4 system is in 4H only the 4X4 indicator circuit is displayed.

No indicators are displayed when the transfer case is in 2H or NEUTRAL mode.
