Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: OBD-II scanner.

2. Connect OBD-II Scanner

Locate the OBD-II port under the dashboard, typically near the driver's side.
Connect the OBD-II scanner to the port and turn the vehicle ignition to the "On" position without starting the engine.
Follow the scanner's instructions to access the ABS system.

3. Clear ABS Codes

Select the option to read or clear diagnostic trouble codes (DTCs) in the ABS module.
Follow prompts to clear any stored ABS codes, which should reset the ABS light.
After clearing, disconnect the scanner.

4. Verify Reset

Start the engine and check if the ABS light is still illuminated.
If the light remains off, the reset was successful. If it stays on, further diagnosis may be required.

5. Final Inspection

Conduct a test drive to ensure the ABS system is functioning correctly and the light does not reappear.
Monitor braking performance and check for any unusual noises.
