"SERVICE 4WD" light on in my 2000 Chevy Silverado?

Truck runs great, cant figure this one out. Fluids ok. Light comes on at various times, then the 2wd light goes out on the selector shortly after. Will a code reader figure this out.

5.3 V8 Z71

Yes it will set a code. Usually a bad encoder motor or switch in the dash.

when the service 4wd light is on will your truck go into 4wd? If not most likely you need to replace the encoder motor in your transfer case.and yes that will set a code that can be checked
