Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to sit for a few minutes to discharge any stored electrical energy.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve any stored ABS-related error codes and note them for reference.

3. Clear Error Codes

Using the OBD-II scanner, navigate to the option to clear the error codes.
Confirm the deletion of the codes and wait for the scanner to complete the process.
Disconnect the scanner from the vehicle.

4. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all connections are secure and free of corrosion.

5. Test the ABS System

Start the vehicle and observe if the ABS light remains illuminated.
Drive the vehicle at low speed to check for proper ABS functionality (braking hard on a slippery surface can help test this).
