Why is my traction control disabled?
A defective, dirty or corroded wheel speed sensor, or a fault in the wiring that connects it, will keep the proper information from getting to the TCS computer, preventing the traction control on that wheel from working. This can cause the system to stop functioning, illuminating the TCS warning light.
What are the symptoms of a bad traction control system?
If the traction control system (TCS) and anti-lock brake system (ABS) share the same module, there may also be problems with the anti-lock brake (ABS) system. 1. Traction Control System Warning Indicator Light is on
What does it mean when traction control light turns on?
Usually, when a light appears on your dash, it signals that something is wrong and needs servicing. However, in the case of a traction control light, most of the time, it means the system is doing its job – but not always. What causes the TCS light to turn on? The most common cause is a loss of traction due to slippery road conditions.
How does the traction control system work on a car?
A set of wheel speed sensors at each wheel control the TCS and ABS (anti-lock brake system) to let your traction control computer know whether or not each wheel is rolling correctly or slipping in any way.
How to turn off service traction control / stabiltrak?
Check that the battery voltage level is above 9 volts. If the battery voltage level is low, perform a charging system diagnosis, parasitic draw test and battery load test. Repair as necessary. 3. Clear DTCs and turn off the ignition for at least 2 minutes. 4. Turn on the ignition and wait for 40 seconds.
What happens when your traction control is disabled?
A problem in the system will usually illuminate a dashboard warning light that traction control is disabled and, in some cases, ABS is disabled as well. (When ABS is disabled, you should still have normal braking, just without the antilock action.)
Why is the traction control light on all the time?
The traction control system (TCS) warning indicator light may be on in the dashboard, and the traction control system (TCS) might remain on all the time or be completely off all together. If the traction control system (TCS) and anti-lock brake system (ABS) share the same module, there may also be problems with the anti-lock brake (ABS) system.
What causes the traction control to go offline?
The traction control computer in your vehicle is the “brain” that controls the entire system. A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light. As the TCS and ABS often share a computer, this may affect your ABS system and turn on that light, too.
What happens when the traction control switch is activated?
The driver applies the brakes: The TCS (traction control switch) will relay data whenever the tires start rotating at a speed that is faster than the speed of the vehicle (known as positive slip). This triggers the ABS system to be activated.
