4 wheel drive service light appears after collision shop replaces bumper
Hey guys, 2016 Yukon XL just had some repair
work done at the collision shop on the fender
(repair list shown in photo. When they put the
truck back together, the "service 4 wheel drive"
light came on. This was not on prior to dropping
off at collision shop. Is there something within the
area of the fender/front door panel that could
trigger this service light?
