SOURCE: Traction Contrl and ABS Light on
No, it is probably not related. Usually the ABS and traction control light is either a wheel sensor problem, located in one of the wheel bearings, or most likely in the wire harness from the wheel bearing sensor. Remove wires and spray clean with a good solvent electric spray, and check the condition of the receptacle. I have had these problems with my 02 AWD so many times it has become almost routine. GM really have a problem with this type of speed sensor in the wheel bearings. In the AWD model, it keeps the car in FWD if the ABS light is on for any reason. JUNK!

I have had exactly the same problem on and off for 3 years now - and just solved it last week thanks to another computer site. Remove and disassemble both grounds from the top of both the left and right frame rails adjacent to the front corners of the engine block. Completely clean the green corrosion from the internal parts with fine sandpaper and add dielectric grease then re-assemble. Clean the mounting bolt and frame hole while you're at it. Sounds time consuming and difficult, but it ain't. No more than 45 minutes combined. I am a technical airhead so if I can do it so can you. What clued me in was the problem always occurred around wet or humid weather. Also, the clock would always lose time overnite. That has ceased also. Good luck. Anyone know why my left headlite, when deployed, vibrates and shimmys??? Sully email@example.com

You'll need to have the codes read from the computer. You will have a code that indicates one of the front wheel sensors is bad. This could be the case, but they are very expensive as they are built into the wheel bearing assemblies. It is more likely that the wiring harness between the frame and the part of the front spindle that holds the harness, has broken internally. It is a very common problem and can be repaired with a new wiring harness section or by tracking down the fault and repairing it.
