Resetting the ABS light after replacing a wheel sensor is a straightforward process that can be done at home with a few simple steps. Typically, the ABS light should reset automatically after addressing the issue, but if it doesn’t, you may need to manually clear the error code using an OBD-II scanner or by following a specific procedure for your vehicle model.
What is the ABS Light and Why Does it Stay On?
The ABS light on your dashboard indicates an issue with the Anti-lock Braking System. When you replace a wheel sensor, the ABS light might remain on if the system hasn’t recognized the new sensor or if there are other underlying issues. Understanding why the light stays on can help you troubleshoot effectively.

Use an OBD-II Scanner:
- Connect the Scanner: Plug the OBD-II scanner into your vehicle’s diagnostic port, usually located under the dashboard.
- Read the Codes: Follow the scanner instructions to read any stored error codes.
