Ours came on early on and I really think it was just me not understanding the shifting/timing of shift etc.. I believe we need to give the vehicle a little bit of time to make the shift to 4WD before we start romping on it. My guess for my situation was I hit the button then got on it and the rear tires slipped with out the front end engaged and the computer saw that as an error. Mine did go our after I came to a stop, properly shut the machine down, Waited 10 seconds and restarted it. I’ve given it plenty of time to make the shift before getting into the throttle hard and not had the light come on again since.
