I have the stability light with wrench come on on my 2006 Trailblazer, what is the problem here?

Check the owners manual, the description is in there under warning indicators. But based on what you describe it sounds like the Vehicle stability system has a fault. There will be a VSC fault code and you need the dealer to read that code and diagnose the problem.

Hello: To determine the cause for the light coming on, you will have to have the system codes read to determine, then diagnose the condition so you can repair it.

It means to service the 4wd system, you will have to have the truck scanned to better diagnose.

{: ) A car swerving light on the instrument cluster is the StabiTrak indicator, sometimes called the traction control indicator. A wrench beside it tells it requires servicing.

Your vehicle is equipped with StabiliTrak, which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
Traction control activates when the controller senses wheel spin. StabiliTrak will selectively apply the brakes and reduce engine torque to help regain traction.
Stability control activates when the controller senses a discrepancy between your intended path and the direction the vehicle is travelling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help guide the vehicle in the direction which you are steering.
When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing.
When the StabiliTrak system is both on and actively controlling the stability of the vehicle, the StabiliTrak light will blink for the duration of the event.
You may also feel or hear the system working. This is normal.
StabiliTrak will turn off automatically if a problem is detected in the system. The StabiliTrak light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak service light) does not clear itself after restarting the vehicle, you should see your dealer for service.

The stabilizer button is located on the left side of the gear shift stick. It is a small oval button barely noticeable. (sort of like an overdrive button that barely sticks out) When you press it or disengage it the stabilizer light comes on. Press it again and it should go off.

Thats the light indicator for your oil change. It is based off of your driving habits, and senses when you should change your oil. You can reset or turn the light off following a basic sequence found in your owenrs manual.

There is a malfunction in the StabiliTrak system.
The only fix is to take it to the dealer. They will more than likely pull a diagnostic trouble code {DTC c0196} and reprogram the EBCM (Electronic Brake Control Module).

This is common problem with
2006-2007 Buick Rainier
2006-2009 Chevy Trailblazer
2006-2009 GMC Envoy
2006-2009 Saab 9- 7X
2006-2009 Isuzu Ascender

Diagnosing and reprogramming is a simple procedure, and most dealers won't charge you to do this service.

Best of luck!

that sounds like a stabilitrack or traction control light. you may need to take the vehicle into a dealer to get it hooked up to a computer to see what the fault is.

Change Engine Oil Light = wrench with a car next to it
StabiliTrak® Service Light = car skidding in a triangle.
This light will come on if a problem is detected in the StabiliTrak® system

may check the safety nuetral switch, it can sometimes ause this....
