This system is tied to your anti-lock braking system (ABS), which controls your brakes and helps them keep your vehicle stable in high-braking situations. This is why a TCS light is often accompanied by the ABS light.

The TCS system is always on unless you turn it off. The TCS button usually has a car with swerving lines coming out of the tires on it. The word “off” is usually printed on the button as well. Refer to your manual to find the TCS button in your specific vehicle. It’s usually either on your turn signal, or the bottom half of your dashboard controls.

If you’re a gearhead who loves working on vehicles, throw your car up on jacks, disassemble the wheels, and inspect the cables running to the wheel sensors. Wrap any exposed wires in electrical tape to see if that solves your problem.

The paper clip in the OBD connector solution may seem strange, but the TCS and ABS lights pop on in Hondas and Acuras when the battery’s voltage is low. The paper clip clears the low voltage signal to your computer and forces it to accurately read the wheel sensors. If the ABS/TCS comes back on, take your vehicle to the mechanic.

If the EPC light comes back on while you’re driving, take it to a mechanic.
