TCS stands for “traction control system,” and it’s one of the most important safety features of your vehicle. It’s responsible for preventing your vehicle from losing traction by performing the following functions:
If you want to learn more about how this system works, read on!
The traction control system is the safety feature that prevents traction loss while driving. It accomplishes this by limiting the speed of the wheels of your vehicle, as one that goes faster than the rest could have your vehicle spinning out of control.
When all the wheels are moving at the same speed, your vehicle will have an easier time sticking to the road’s surface or any other terrain you’re driving on.
The TCS usually activates on its own when your vehicle’s computer detects problems with the tires, namely when one loses traction and slips and slides on the road. Because this problem often occurs when driving on slippery surfaces, you can expect the TCS to activate frequently when it’s raining or when the road is slick with ice.
The TCS can detect when your tires lose traction with the help of wheel speed sensors and yaw sensors, which monitor the individual and overall speed of the wheels. When a tire loses traction, it spins faster than the others. To combat this, the TCS will activate and slow the wheel to help it regain traction.

When the TCS light, also known as the traction control light (TCL), on your dashboard lights up, it simply means your vehicle’s TCS is working as intended.
This light activates when your vehicle needs to activate its TCS, such as when you’re driving uphill, while it’s raining, or on icy roads and other slippery surfaces.
The TCL also illuminates when one of your vehicle’s tires loses traction, prompting the TCS to adjust by allocating more power to the same tire.
A lit TCL is simply your vehicle’s way of keeping you informed, and it should disable on its own after driving conditions are more stable.
Something wrong with your TCS if the TCL is on when it shouldn’t be (when you’re driving slowly, in good weather, or on flat and dry roads).
If the light remains lit, it’s possible that the TCS has been deactivated entirely and your vehicle’s computer can’t detect when it’s time to reactivate the traction control system.
While this isn’t a problem if you’re driving in stable conditions, it’s still important to reactivate the TCS as soon as possible.
If the TCL activates and remains on while driving, your TCS might be malfunctioning. It’s best to have it inspected at an auto shop to get the traction control system back in shape.
Push comes to shove, you could always replace your vehicle’s traction control module. Bear in mind that a replacement traction control module costs around $600.
No, the TCS cannot make your vehicle go faster. The TCS can adjust the speed of your vehicle’s wheels but only to make them go slower to compensate for their counterparts that have lost traction.
Generally, you should replace your traction control module when an expert who examines your vehicle tells you to do so. Typically, they’ll tell you to do this when the TCS malfunctions or when it stops activating when it should. TCS problems usually cause the TCL to flash or stay lit.
Don’t replace your traction control module unless a diagnosis tells you to do so. Just because traction control doesn’t work doesn’t mean the module itself is responsible.
No, it doesn’t because the TCS doesn’t depend on the fuel system. It draws electricity from the car battery to power itself and the sensors it relies on.
“TCS Off” means your vehicle has its traction control system disabled.
Though it’s inadvisable, yes, you can still drive your vehicle with the TCS off. Doing so can be dangerous, especially if you’re driving on slippery roads because your vehicle can easily skid out of control.
Even though the TCS should be on almost all the time, there are some situations where it’s better to disable it. For example, when your car gets stuck in mud or snow, the TCS can work against you if you want to get out.
