What Does TC Mean on Cars?

December 4, 2023

The traction control (TC) system is an important safety feature that is designed to increase the grip of your car's tires on the road in bad weather conditions. The system works by monitoring the speed of each wheel and changing engine power or selective braking to reduce the likelihood of your wheels spinning. The traction control system doesn't have any impact on your gas mileage and will only turn on when the vehicle's computer notices that one or more of your wheels is losing traction.

Depending on the model of your car, there are different ways that the traction control system can be turned on or off. For example, it could be activated by pressing a button on the center console that looks like a car with skid marks or with the acronym TC written in it with a slash through it.

Traction control is typically activated by the same button or switch that also activates other safety features like anti-lock brakes and stability control systems. The traction control warning light on your dashboard should illuminate for a brief period every time you start your car to indicate that the system is active and working to keep you safe. It may also be accompanied by the image of a car with skid marks or the acronym TC with a line through it, depending on your car's model.

If the traction control system warning light stays on for extended periods, it is a sign that something has gone wrong and that your car's traction control or stability control system is disabled. The best thing to do is to contact a mechanic as soon as possible, since this can lead to some serious problems if left unchecked.
