Warning messages

I have two warning messages on my 2005 Jeep GC CRD , one is "Service elec brake system" and the other "Service 4wd". In addition the ABS and Traction control lights are on. If I do not use the vehicle for a couple of hours, the lights stay off for about the first twenty miles. It does not seem to affect the performance but sends my fuel readings all over the place plus I lose cruise control.
However there is one worrying aspect. On one or two occasions, when pulling off from traffic lights, only the traction control light has come on and the vehicle drops into a limp mode with no acceleration and crawls across the intersection. The Traction Control light then goes out and all is back to normal except my trousers! It is suspected that the fault code reads rear right side ABS sensor faulty.
Any suggestions? Thanks.

Yes the ABS Wheel Speed sensor is one unit. One on each wheel, connected to the wheel hub assembly. Their replacement is a common fix to your problem. If your model is capable, do the key dance trick and get the codes so you can determine which wheel/side is the problem. :thumbsup:
