Reasons for Having a Glowing Traction Control Warning Light

The traction control system in your car exists as a driving aid during adverse conditions such as rain, snow, ice or poorly maintained roads.

And when the system is faulty, it will illuminate a warning light on the dashboard cluster, which is either in the form of the acronym “TC” or a small illuminated picture of a car losing control.

The traction control uses wheel speed sensors to know when one or more of the car's wheels lose grip and traction.

When the system registers a loss of traction in the wheels, a computer will reduce power to the wheels that are still in good contact with the road to prevent a skid.

Here are some of the common reasons for having a glowing traction control warning light on your dashboard. 1-Malfunctioning ABS 2-Broken Speed Sensor 3-Faulty Traction Control Module

Traction control and ABS systems, often use the same control module and the internal self-diagnostics system.

As a result, sometimes an issue in the ABS can put on the traction control light as well as the ABS light.

The speed sensors are usually in the wheel bearing assembly and determine the rate at which each wheel is moving.

These sensors, relay that signal to the traction control module, which determines whether or not power should be shifted.

Wheel speed sensors can get dirty or damaged and stop working, which stops the traction control module from knowing when to enable the system.

The traction module itself can malfunction and completely breakdown, making the system to stop working.

In such a case, the module needs to be replaced completely for securing your drive to be safe and comfortable.

It is quite necessary to have the traction control issue to be resolved quickly in order to avoid adverse driving conditions.

While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in the rain, snow or other inclement weather.

Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS system of the car.
