Solution

1. Preparation

Gather necessary tools and equipment, including an OBD-II scanner, socket set, and cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Navigate to the ABS section of the scanner and retrieve stored fault codes.
Note down any codes for further analysis if issues persist.
Clear all fault codes using the scanner's interface.

3. Inspect Components

Inspect the wheel speed sensors:
- Locate each wheel speed sensor, usually mounted near the brake rotor.
- Check for damage or obstruction; clean any dirt or debris from the sensor area.
Verify the ABS control module connections:
- Disconnect the ABS module connector and inspect for corrosion or loose connections.
- Reconnect securely after inspection.

4. Check Brake Fluid

Locate the brake fluid reservoir under the hood.
Ensure the brake fluid is at the proper level; top off with the manufacturer-recommended fluid if necessary.

5. Test Drive

After resetting, take the vehicle for a test drive to ensure the ABS system is functioning correctly.
Monitor the ABS warning light; it should remain off during the test drive.
