Solution

1. Preparation

Gather tools including an OBD-II scanner, multimeter, socket set, and repair manual.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Resolve Fault Codes

Use an OBD-II scanner to clear any stored fault codes related to the ABS.
If any codes reappear after clearing, note them for further diagnosis.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench
Locate the wheel speed sensors at each wheel hub assembly.
Disconnect the electrical connector and remove the sensor using a socket.
Inspect the sensor for damage; if faulty, replace with a new sensor.
Torque the new sensor to the manufacturer's specification (typically around 7-9 ft-lbs).
Reconnect the electrical connector.

4. Check and Replace ABS Module (if necessary)

Tools Required: Socket set, wrench set
Locate the ABS module, typically found near the master cylinder.
Disconnect the battery and remove the electrical connectors from the ABS module.
Unbolt the module from its mount and remove it.
Install the new ABS module and torque to specifications.
Reconnect the electrical connectors and battery.

5. Refill and Bleed Brake System

Check the brake fluid level in the master cylinder reservoir and fill as needed with the proper brake fluid type (DOT 3 or DOT 4).
Bleed the brakes using a brake bleeder kit to remove any air trapped in the system.

6. Test Drive

Reconnect the negative battery terminal and start the vehicle.
Perform a test drive to ensure the ABS system is functioning correctly and the light remains off.
