What is the Traction Control System And Warning Lights?
The traction control system (TCS) on your car is what makes your car a firm and grippy machine. It connects to your ABS to prevent wheels from locking up. This is particularly relevant when it is not weather or when driving on wet roads.
How the Traction Control System Works?
The TCS monitors each wheel and brakes the turning one. It pumps power to grippy wheels. That puts you in control, without skidding or fishtailing.
Different Types of Warning Light Patterns
If the TCS diagnoses a glitch, it will illuminate your dashboard’s ABS or TCS light. These lights may go on and off as a sign of an ailing system needing repair.
Relationship Between TCS and ABS Systems
The ABS and TCS pair up to stabilize your vehicle. ABS prevents wheels from squeezing when you apply big brakes.
The TCS makes your wheels grippy, even on a slick road. You need to know how these systems operate for your car’s safety and performance.

Common Reasons Why Your Traction Control Light Stays On?

The wheel speed sensor is a big cause of a stuck TCS light. These sensors measure how fast each wheel is turning. If the sensor isn’t performing as expected, it can flash the TCS alert.
Also, a brake problem is a common issue. TCS must have the brakes mapped just right to stop the car. It can activate the TCS light if the brakes are faulty.
Also, problems with the car’s computer can leave the TCS light on. These identifiers tell you when something might break. If these codes are incorrect, you could turn off the TCS light.
