Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket set.
Carefully pull the sensor out of the hub and clean it with brake cleaner.
Inspect the sensor for damage; replace if necessary.
Reinstall the sensor and secure it with the mounting bolts to the manufacturer's torque specification.

3. Replace Damaged Wiring or Connectors

Identify any damaged wiring or connectors during inspection.
Cut out the damaged section of the wire and strip the ends.
Use a soldering iron to connect the wires or use heat-shrink connectors as an alternative.
Ensure connections are insulated and secure.

4. Replace the ABS Module (if necessary)

Disconnect the battery again before proceeding.
Locate the ABS module in the engine bay or under the vehicle, depending on the model year.
Remove the mounting bolts using a socket set and disconnect the wiring harness.
Install the new ABS module by reversing the removal steps, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer's specifications.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the vehicle and check if the ABS light remains off.
Perform a brake test to ensure ABS is functioning correctly.
