What does the TC light mean on a Chevy Traverse?

The TC light on a Chevy Traverse indicates Traction Control. It signals whether the system is active, has been turned off, or is indicating a fault. A blinking light usually means the system is actively reducing wheel spin to improve grip, while a steady light can mean the system has been disabled or there is a fault requiring service.

Understanding Traction Control and its companion systems

Traction Control is part of Chevy’s broader stability system (often marketed as StabiliTrak). It works with the brakes and engine to help keep the wheels from spinning on slippery surfaces. The light can appear in several ways depending on driving conditions and factory settings.

Common ways the TC light behaves

Below are the typical meanings behind the light’s behavior. This helps you know what to expect in everyday driving.

Light blinking during acceleration on slick surfaces: Traction Control is actively working to curb wheel spin and maintain grip. This is normal and usually short-lived.

Light solid on with the “OFF” indicator visible: Traction Control has been manually disabled by the driver, or a fault has triggered a condition that requires attention.

Light off while driving: Traction Control is functioning normally and not currently limiting power or applying brakes.

In practice, a blinking TC light is a normal sign the system is doing its job, while a persistent solid light (especially with an accompanying “OFF” notice) warrants attention.

What to do if the TC light comes on

When the TC light illuminates, consider the driving context and any accompanying warning lights. Here are steps to take if you see it appear on the dash.

On slippery or uneven surfaces: Continue driving with caution. The system is helping you maintain traction, and frequent braking or sudden acceleration should be avoided.

If the light is solid with “TC OFF” or similar text: Press the Traction Control button to re-enable the system. If it stays on after re-enabling, or comes back on repeatedly, a professional diagnostic is advised.

If the light remains on after restarting the vehicle: Schedule service to check for sensor, circuit, or computer faults within the traction/stability system.

Notes for practical maintenance: Confirm tire pressures are within spec and tires have similar wear. Uneven tires or mismatched tread can trigger traction/stability concerns and illuminate the TC indicator.

When to seek professional help

Persistent or recurring TC light activity beyond normal driving scenarios may point to a fault in the Traction Control, ABS, or StabiliTrak system. A diagnostic check with a scan tool can identify sensor or module issues, and a dealership or qualified shop can address software updates, sensor replacements, or brake-system concerns as needed.

Related indicators you might see

Other warning lights sometimes appear in tandem with the TC light. Knowing what they mean can help you respond appropriately.

ABS warning light: May indicate a braking-system issue that can interact with traction control.

StabiliTrak indicator: Refers to the overall stability system; issues here can affect traction control performance.

Tire pressure monitor: Improper tire pressures can influence traction and stability readings.

If you notice multiple warning lights, or the TC light remains on while driving on dry pavement, it’s prudent to have the vehicle inspected sooner rather than later.

Summary

The TC light on a Chevy Traverse identifies Traction Control activity and status. A blinking light generally means the system is actively managing wheel spin, while a solid light can indicate the system has been deactivated or is signaling a fault. When in doubt, re-enable via the TC button, check tire conditions, and seek professional diagnostics if the light persists or is accompanied by other warning indicators.

Bottom line

Traction Control helps you stay stable on slippery roads by limiting wheel slip. Treat a blinking TC light as normal operation, and address a solid light with care, especially if it doesn’t clear after re-enabling the system or if other warning lights are present.
