Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (sockets, wrenches)
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Connect OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition to the "On" position without starting the engine.

3. Retrieve and Clear Codes

Follow the scanner’s instructions to read the Diagnostic Trouble Codes (DTCs).
If codes are present, make a note of them. Clear the codes using the scanner’s "Erase" function to reset the ABS light.

4. Perform Brake System Check (if necessary)

If the ABS light returns after clearing, perform a thorough inspection of the brake system, including brake pads, rotors, and hydraulic components.
Address any issues found before attempting to clear the ABS light again.

5. Test Drive

After clearing the light, take the vehicle for a short test drive to ensure the ABS system is functioning correctly and the warning light does not reappear.
