The traction control in your vehicle assists you in driving on slippery surfaces and helps your wheels keep traction on the road. The system is normally activated when the throttle input and engine torque do not match the surface of the road The traction control module is the sensor that tells the vehicle when to automatically turn the traction on and off. In addition, the traction control can be turned on and off with a switch, but it is much easier to use automatically as your vehicle does it for you.
The traction control module uses the same wheel-speed sensors as the anti-lock braking system does. These systems working together to help minimize wheel slip while you are accelerating and driving on slippery roads. Components of the traction control system include the module, connectors, and wires.
The traction control module is connected at each wheel so they can accurately detect when the traction control needs to be turned on. The sensors are subjected to dirt, snow, water, stones, and other road debris. Along with being exposed to these on a regular basis, they can also go bad due to electrical problems.
If the module is not working properly, the Traction Control light will illuminate on your dashboard. If this happens, the light needs to be inspected and diagnosed by a professional mechanic. Since the traction control works closely with the ABS, be sure to take note if your ABS light comes on as well. If your anti-lock braking system is disabled due to a problem with your traction control module, you will be able to brake normally but they may lock up if you push on them suddenly.
Since the traction control module can go bad and fail over time, it is important that you can recognize the symptoms it gives off before it completely fails.
Signs that indicate your traction control module needs to be replaced include:
- The ABS is not working correctly
- The Traction Control Light is on
- The brakes lock up when you come to a sudden stop
Since the traction control and ABS work together, this repair should not be put off as it can be a safety hazard. Have a certified mechanic replace the failing traction control module to eliminate any further problems with your vehicle.
