Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, multimeter, and safety gloves.
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the brake fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
4. Replace the cap securely.

3. Clear ABS Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
2. Turn the ignition to the "ON" position without starting the engine.
3. Follow the scanner’s instructions to navigate to the ABS system and retrieve any stored fault codes.
4. Once noted, select the option to clear or reset the codes.
5. Turn off the ignition and disconnect the scanner.

4. Test ABS Functionality

Sub-steps:
1. Start the engine and observe if the ABS light remains illuminated.
2. Drive the vehicle at a low speed (around 15 mph) and perform a hard brake application to test the ABS system.
3. Ensure that the ABS engages (you should feel rapid pulsing in the brake pedal).
