What is what does it mean when your traction control light comes on?

The Traction Control System (TCS) light illuminates when the system is actively engaged or when there is a malfunction. Here's a breakdown:

• Active Engagement: The light often flashes when the TCS is actively working to prevent wheel spin, especially on slippery surfaces like ice, snow, or gravel. This is normal operation and indicates the system is helping you maintain control.

• System Malfunction: A steady, illuminated TCS light usually indicates a problem within the system. This could be due to a faulty wheel speed sensor, a problem with the ABS (Anti-lock Braking System) (which often works in conjunction with TCS), a damaged wiring harness, or an issue with the TCS module itself.

• Disabling TCS: Some vehicles allow you to manually disable the TCS. If you've accidentally turned it off, the light might be on to indicate that the system is not active. Check your owner's manual for instructions on how to enable/disable TCS.

• Potential Issues: A lit TCS light can be related to problems with other systems, such as the Engine Control Unit (ECU).

It's essential to have the issue diagnosed by a qualified mechanic if the light remains on continuously, as it could affect your vehicle's handling and stability.
