Terrain management system light on?

Hi David,

This is the Roll Stability Control system. This is part of the ABS and stability control system. Basically this portion of the system is looking primarily at the rotation of the steering wheel but it also looks at the stability control sensor cluster. However, the way this is happening it sounds like the steering rotation sensor is sending an erratic signal when you are turning the wheel. It happens so fast because as you turn the wheel it quickly recovers the proper signal.

The way to verify this is to monitor the sensor operation with a scan tool and see what it is saying. More than likely if you are able to graph it on a scan tool you will see when the light flashes the signal goes erratic at the same time.

Here is the material about this system. More than likely you have some diagnostic trouble codes in the computer so if you can pull those and send them I can give you more detail on on to test it.

Let me know if you can get the codes your self and if not, most parts stores will pull them for you for free. Let me know and we can go from there. Thanks

Hi,

I'm not familiar with the scan tool you have. I'm not sure if what it is capable of doing. Sorry about that.

Please let me know how things turn out or if you have other questions.

Take care,
Joe

Hi,

Keith, sorry to ask this, but is it possible for you to copy and paste your entire thread to a new posting. We are trying to keep the posts specific to one topic. I'm sure someone will jump right on your question.

Again, sorry for asking, but I hope you understand.

Take care,
Joe

Chances are there is a sensor that is the problem. What you need to do is take the vehicle to a nationally recognized parts store and have the computer scanned for codes. Most will do it for free.

Let me know what you find.

Joe

The two systems work together. Therefore, I would start by checking the ABS sensors. Since the lights are on, This video will show you how

Please run down this guide and report back.

Could very well be. To be sure the system will need to be scanned for codes. If a wheel sensor or some wiring was damaged, then the traction control/ABS system will turn on the light letting you know there is a problem

What do you mean by "I don't have control"? Is the steering wheel moving by itself, with no input from you? Is the engine stopping and starting with no input from you? Do the brakes spontaneously apply? What does the noise sound like? Where does it come from?
