just came on in my new to me truck. just lights up in the odometer readout screen. havne't pulled codes yet. but will tomorrow. i googled it and found it could be the motor or relay or something? don't know. when the light was on the truck was in 2wd. i didn't try to put it in 4wd. i turned the truck off and the indicator went away, and truck shifted into 4wd. (lights changed at least)
