One problem related to brake abs warning light has been reported for the 1998 Jeep Cherokee. The most recently reported issues are listed below.
I think my Jeep is remotely bugged somehow, abs light comes on and my brakes work, abs light goes out and my brakes make noise and pedal goes down further like I have no brakes. Also, temperature gauge is steady then suddenly it goes up and down. I have checked fluids, had brakes inspected (replaced pads and front rotors) I went to police said they had no way of testing for bugs.
