Traction control is a vehicle safety feature designed to prevent wheel slip and loss of traction during acceleration by regulating the power delivered to the wheels. It works by monitoring wheel speed and detecting when one or more wheels are spinning faster than the others, indicating potential loss of traction.

When traction control detects wheel slip, it automatically reduces engine power and/or applies braking to the spinning wheel(s) to help regain traction and stabilize the vehicle.

ABS stands for Anti-lock Braking System. It’s a safety feature in vehicles designed to prevent wheels from locking up during braking, which helps maintain steering control under hard braking and reduces stopping distances.

While ABS is normally adjusted by one control, perhaps mapped to your steering wheel, traction control can have more than one. For instance, in iRacing there are two controls, labelled TC1 and TC2.

Some cars do not have traction control, or ABS for that matter, at all. While others will implement traction control in a more complicated or different way to others.

You will have to find out how a particular car you may be driving makes use of the system and use it accordingly.
