Large WHEELS can't affect anything like that because what counts is the outside diameter of the TIRES. The vehicle can't possibly know what diameter wheels you have on.

So WHICH 4X4 light is on? One of the mode lights on the selector switch or the "Service 4WD" light on the dash?

Have you been regularly exercising your 4WD system as recommended to keep the actuators lubed up and ready to go when you need them to work? How about just turning the selector switch from end to end 40-50 times with the ignition OFF, to scrub off any oxidation on the contacts?

Try that and then let us know what happens.
