If the buttons do not light up, the shift motor, the four-by-four module or the dash button may be faulty. To check which component has the issue, press the four-by-four button and to listen for any sounds in its relays.

To diagnose any problem with the four-by-four module, disconnect the two connectors connected to the left portion of the module and turn on the car. Press the reset or test button, and check whether the LEDs flash four times. If the LEDs continuously flash or do not flash at all, the issue is with the module.

If the four-by-four module is working as expected, check the switch, the magnetic clutch or the wiring harness for any damage. If the vehicle makes noise below the front wheels, check whether the hub locking is correct.
