Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical issues.

2. Address Underlying Issues

Inspect and Repair: Based on diagnostic codes, repair or replace any faulty components such as ABS sensors, wiring, or the ABS module.
Brake Fluid Check: If fluid levels are low, top up with manufacturer-recommended brake fluid (DOT 4) and check for leaks.

3. Reset ABS Light

Reconnect the negative battery terminal after repairs are completed.
Use an OBD-II scanner to clear the fault codes:
1. Connect the scanner to the OBD-II port (usually located under the dashboard).
2. Turn on the ignition without starting the engine.
3. Navigate to the ABS menu in the scanner.
4. Select “Clear Codes” or “Reset ABS Light.”
