Most likely a bad wheel speed sensor

have a technician drive it with a scan tool and monitor all VSS

I suspect one if off
You can also confirm this buy trying to lock up the brakes in a safe location

if ABS activates early/late or not at all this too is a sign of a VSS concern

I keep getting a message service stabilitrak


StabiliTrak Indicator Light: If the warning light does not come on then, have it fixed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly.

This light will also flash when the StabiliTrak system is active. If the StabiliTrak system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service.

The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both traction control and StabiliTrak, press and hold the button for five seconds.

Traction control and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason.

When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate TCS off or StabiliTrak off message will be displayed on the DIC to warn the driver. Your vehicle will still have brake-traction control when traction control is off, but will not be able to use the engine speed management system.

If the StabiliTrak and/or Traction Control are not operating properly, I encourage you to take your vehicle in for inspection. A certified technician will be able to offer a more accurate diagnosis.

My service stabletrack keeps come on how to fix that


Hi there:

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.


Hope this helps.

Light comes on "Traction Active" and wheels lock down.


Hi:
When the Engine Control Module encounters problems, it will also disable the traction control system. Scanned the ECM to know fault codes stored there, repairing this codes and clearing the codes will turn off the Traction indicator and allows the traction control to work once again.

If the Traction Control light is coming on, the traction control is activating and can cause a jerking problem. Nothing last the life of the vehicle, however the timing chain should not need to be changed at 49,000 miles. If it does, I would have them do it under warranty. See if you can get the codes and send them to me. That way we can get a better ideal of what is going on. Could you please tell me what these codes stand for?

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Service traction light keep coming on and the traction active light when backing up, making right turns, and just driving.


This light is telling you that there is an electronic fault that only a "scan" tool can decipher. Ask your friends who their mechanic is, have it scanned, and have it serviced. Problems like this cannot be repaired over the internet.

I have a wrench with a car swerving light up every once in awhile but I have no idea what it means and I have no idea what stabilitrak is


{: ) 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.

There are wheel speed senors that tell the computer about wheel slippage. One or both are malfunctioning or the wiring is chaffed.
