The traction control helps in maintaining the grip on surfaces while sudden acceleration or braking, by regulating the engine torque. Also, the traction control light turns on whenever there is a component failure related to the traction control system. There is a check light for the traction control in the instrument console of the cars which are equipped with this feature, which turn on whenever there is any fault detected anywhere in the car. So, today in this article, we will tell you the top five reasons why the traction control check light glows on in a car.
Now, while the Anti-lock Braking System (ABS) has become a mandatory feature in all modern cars, another system related to the braking purpose which is considered to be essential is the traction control system. Primarily found in some expensive premium cars, the traction control system aids in maintaining the grip on the surface when there is a sudden change in the acceleration or braking tasks, by regulating the engine torque. Here are the top five reasons why the traction control check light glows on in a car:
Bad Driving Conditions - While traction control is quite an effective feature for handling bad roads with ease, there are some terrains that are too bad for even traction control to work. Circumstances like too heavy fog and water-logged rocky roads are difficult for traction control to work flawlessly, which can lead to the traction control light turn on.
Faulty Wheel Speed Sensors - Apart from the crucial functioning of the Anti-lock Braking System (ABS), the wheel speed sensors are also an integral part of the traction control system. If these sensors stop working, the traction control system will fail to receive any signal, causing the signal to glow on and loss in traction.
Electrical Fault - Since the traction control system is a part of the electrical system and relies heavily on the wiring and sensors involved, there can be a wiring or programming issue somewhere in the system which can turn the traction control light on.
Damaged Steering Rack - For effective working of traction control, the steering system should be in optimum condition, for the latter comes in handy when controlling your manoeuvrability in difficult driving conditions. If the steering rack, which is one of the most important components of the steering system, gets damaged due to leakage of hydraulic fluid, the steering can get hardened and difficult to move, which can turn on the traction control check light.
Defective Steering Angle Sensor - Another component of the steering system which is required for effective manoeuvrability is the steering angle sensor. Placed in the steering column, it is used to detect the direction of the movement of the car. If this sensor fails, the traction control system will be unable to detect the very direction and catches it as an error, resulting in turning on the check light of the traction control system.
