Note: If AWD icon comes on, instru-
ment cluster is O.K. Proceed to me-
chanical tests (in Service Manual).
Check the AWD icon on instrument clus-
ter to verify it's operation. The AWD
switch is directly powered by switched
12 volts (red/white). The gear switch
only interfaces with the instrument clus-
ter. To enable AWD, the cluster must be
displaying low or high gear, or reverse
gear with the override button pushed in.
