Pontiac Montana SV6 my traction control,abs and tire monitor

Resolved Question:

my traction control,abs and tire monitor lights are on all and off more on than off. I hateb the traction thing anyway and it does seem to be not doing much since the ligght have been on. i think it must be a wiring problem (hopefully a harness conection) ANY ADVICE WHERE TO START WOULD BE GREATLY APPRECIATED.

Welcome, and thanks for using Just Answer. I am Cam, and I will do my best to assist you. When you are finished please click on accept only if you are satisfied. I don't get paid unless you do.Please do not accept if you cannot leave positive feedback. I don't know if you are a tech or a just working on your own vehicle so we may have to fine tune the answer. I only know as much about your problem as you have told me in your post, so my answers will be based on what you tell me so please add all the details you can. About your vehicle,

There is a bulletin from GM about this, and often the issue is a bad connector at one of the wheel speed sensors or the wiring is chaffing on the side of the transmission housing. The place to start is a thorough inspection of the wiring and terminals. If they all look good, then you will need to use a scan tool to see which wheel is causing the issue then concentrate on that wheel speed sensor and wiring.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

 

TAC has received several calls in regards XXXXX XXXXX DTCs C0460, C0461 (Steering Position Sensors), C0187 (Lateral Accelerometer Circuit Range/Performance), C0196 (Yaw Rate Circuit) and/or C0252 (VSES sensor uncorrelated). Initial investigation has found the forward engine harness routed from the EBCM, underneath the inlet air breather box and across/down the transmission may have several points where it may come in contact with the transmission stud or A/C line creating a short to ground.

Recommendation/Instructions:

 

Inspect the complete forward engine wiring harness and repair as needed, wrap with protective tape inside and outside the conduit. The harness should be re-routed to avoid contact with the air conditioning accumulator, transmission mounting studs and/or any sharp edges.
