Who can help me talking about the causes of this problem? My Jeep Wrangler Sahara 2.0 year 2019 has switched on this warning light every time in 4x4 over bad terrain, after I stop the vehicle and turn the SERV 4WD warning light off again. The dealership here in Brazil has little knowledge about this car model and has not yet solved the problem. I live in Brasilia, capital of Brazil.

Hi my situation was different, after installing a teraflex st2 kit I had the service 4wd I couldn’t get rid of it. I took it to the dealer and they replaced the front FAD but it did nothing. The dealer then download some software from FCA and the light went away for good. Not sure if that helps. Hi from Canada.
