Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (sockets, wrenches), brake fluid, cleaning supplies.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Repair Faulty Wheel Speed Sensors

Remove the Wheel: Use a jack to lift the car and a socket to remove the lug nuts. Take off the wheel to access the wheel speed sensor.
Disconnect Sensor Connector: Locate the wheel speed sensor and carefully disconnect the electrical connector.
Remove Sensor: Unscrew the sensor from its mounting using the appropriate socket.
Inspect and Clean: Examine the sensor for dirt or damage. Clean the sensor and the mounting area with brake cleaner.
Replace if Necessary: If the sensor is damaged, install a new sensor by reversing the removal steps.

3. Check and Refill Brake Fluid

Locate Master Cylinder: Open the hood and find the brake master cylinder.
Inspect Fluid Level: Check the brake fluid level. If it's low, clean the reservoir cap, remove it, and top it off with the manufacturer's recommended brake fluid.
Reinstall Cap: Securely fasten the cap back on the reservoir.

4. Repair or Replace ABS Module (if necessary)

Access ABS Module: Locate the ABS module, typically near the brake master cylinder.
Disconnect Wires: Carefully disconnect the wiring harness and any associated connectors.
Remove ABS Module: Unbolt the module and remove it from the vehicle.
Install New Module: If the module is defective, install a new ABS module by reversing the removal steps.
Reconnect Wires: Ensure all connectors are securely fastened.

5. Final Steps

Reconnect Battery: Reconnect the negative battery terminal.
Clear Codes: Use the OBD-II scanner to clear any ABS codes from the system.
Test Drive: Perform a test drive to ensure that the ABS light does not reappear and that the brakes function correctly.
