Normal Operation
With the key in the ON position, the 4WD control module receives the operator's choice of all wheel drive selection from the mode select. The 4WD control module then controls the electric clutch. If the transfer case is not responding to the operator's intentions, systematically check all inputs and outputs to the 4WD control module.
