possible wheel sensor and 4WD
i'm asking this for my sister, she has a 2008 Liberty. after she starts the car the ABS, Service 4WD, Traction Control, and ESP lights stay on.
because of this the 4WD does not work, which makes the thing useless up here in the northeast in the middle of winter.
is this a sign of a bad wheel sensor? before she takes it to a dealer and spends 100 bucks to have them pull the codes.
also, is it possible to force it into 4WD or will it simply not engage while the computer is throwing codes?
