How do you reset the Trac off light on a Toyota?
The quickest way to reset the TRAC OFF light is usually to re-enable traction control with the TRAC OFF switch or by cycling the ignition. If the light stays on, there may be a fault that needs diagnosis from a technician.
This article explains what the TRAC OFF light means on Toyota models, how to perform a basic reset, what to check if it doesn’t reset, and model-specific notes. The guidance covers common steps across recent Toyota cars, but exact button locations and procedures can vary by year and model.
What the TRAC OFF light means
The TRAC OFF indicator signals that the vehicle’s traction control system (part of Toyota’s stability control and ABS suite) has been turned off or is not functioning properly. It may come on when you manually deactivate traction control, or it can illuminate if the system detects a fault in components such as wheel speed sensors, ABS hardware, wiring, or the power supply. If the light appears alone when you haven’t pressed the TRAC OFF switch, or if it stays on after you re-enable traction control, there is likely an issue that needs attention.
Manual disable versus system fault
If you turned traction control off intentionally, you can typically re-enable it without special tools. If the light remains after you try to re-enable, or if it comes on by itself and stays on, treat it as a potential fault that should be diagnosed.
To re-enable traction control after a deliberate toggle, follow these steps. If the light does not respond, proceed to the next steps in this article.
- Locate the TRAC OFF button (often labeled with the word "TRAC" or an icon showing a car with skid marks) and press it to re-engage traction control.
- Drive at a moderate speed and observe whether the TRAC OFF light turns off within a few seconds as the system resumes normal operation.
- If the light remains on, turn the ignition off, wait about 10–15 seconds, then start the engine again and press the TRAC OFF button once more to re-enable traction control.
If the light continues to stay on after these steps, there may be a fault in the traction control system, ABS, or related sensors requiring a diagnostic check.
What to do if the TRAC OFF light stays on or recurs
When the TRAC OFF light remains illuminated or reappears after a reset, it is a sign to inspect the system for possible faults. The following steps help identify common causes and guide you toward a fix. This information is general and may vary by model and year.
- Check for other warning lights. If the TRAC OFF light is on with ABS or VSC indicators, the issue may involve the stability/ABS system or wheel speed sensors.
- Inspect wheel speed sensors and wiring. Damaged connectors, corrosion, or a dirty sensor can trigger traction control faults.
- Scan for trouble codes with an OBD-II scanner. Codes related to ABS, traction control, or wheel speed sensors can pinpoint the faulty component.
- Inspect the brake system and battery health. Low battery voltage or weak charging can cause intermittent traction control warnings; test the battery and alternator if needed.
- Address identified faults. Replace or repair faulty wheel speed sensors, ABS components, wiring, or related hardware as indicated by codes and inspection.
- Clear codes after repairs and perform a test drive to confirm the light does not return.
If you are not comfortable performing diagnostics, or if the light reappears after repairs, contact a Toyota dealer or a qualified mechanic for a thorough inspection. Driving with a persistent TRAC OFF warning can affect vehicle stability in slick conditions.
Model-specific notes
While the general approach is similar across many Toyota models, the exact button placement and behavior can vary by year and trim. Some models place the TRAC OFF switch near the steering column; others place it on the center console. In hybrids or vehicles with advanced stability control, the system may behave differently during start-up or under certain driving conditions. Always consult your owner’s manual for precise instructions for your vehicle and model year.
Summary
To reset the TRAC OFF light on a Toyota, try re-enabling traction control with the TRAC OFF switch or by cycling the ignition. If the light persists, perform a diagnostic check using an OBD-II scanner to identify potential faults in wheel speed sensors, ABS components, wiring, or the battery/charging system. For persistent or recurring warnings, have a professional inspect the system to ensure safe driving, especially in wet or slippery conditions.
What causes the trac off light to come on?
The "TRAC OFF" light comes on because the traction control system has been intentionally or automatically disabled. Common causes include a low-traction driving situation (like snow or mud), a problem with a wheel speed sensor, a fault in the anti-lock brake system (ABS), or a malfunctioning computer or sensor within the vehicle. If both the TRAC OFF and check engine lights are on, it suggests a deeper engine or system issue that needs professional diagnosis.

Common causes
- Poor road conditions: The system may turn off temporarily if it detects a lack of traction, such as on ice or snow. The light will blink, then stay on if it's a sustained condition.
- Wheel speed sensor issues: A faulty or dirty wheel speed sensor can send inaccurate data to the control module, causing the system to shut down.
- Anti-lock brake system (ABS) problems: The traction control system is linked to the ABS. If there's an issue with the ABS, the traction control system may be disabled.
- Mechanical or electronic faults: Problems with other components, such as the brake light switch, steering angle sensor, or the traction control system's computer itself, can cause the light to come on.
- Engine issues: If an engine problem triggers the check engine light, it can also cause the traction control to automatically turn off as a safety precaution.
What to do
- Try restarting the engine: Turning the vehicle off and then back on may reset the system. However, this won't fix the underlying problem if there is one.
- Check your driving conditions: If you are on a slippery surface, the system may be working correctly to prevent wheel spin.
- Look for other warning lights: If other lights, such as the check engine or brake warning lights, are on, it indicates a more significant issue that needs to be diagnosed by a mechanic.
- See a mechanic: If the light stays on after a restart or you experience other warning lights, take the vehicle to a professional. They can use a diagnostic tool to read the error codes and pinpoint the exact problem.
