Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical accidents.
Gather all necessary tools and parts.

2. Inspect and Replace Faulty Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket set.
Disconnect the electrical connector from the sensor.
Inspect the sensor for dirt or damage.
Install the new sensor by reversing the removal steps, ensuring it is securely mounted and connected.

3. Repair or Replace ABS Module

Remove the ABS module by disconnecting its electrical connectors and unbolting it from the mounting bracket.
Inspect the module for signs of damage or corrosion.
If necessary, replace the ABS module with a new or refurbished unit.
Reinstall the module, ensuring all connections are secure.

4. Bleed the Brake System

Reconnect the battery and ensure the ignition is on.
Use a brake bleeder kit to bleed the brake lines, starting from the furthest wheel from the master cylinder (usually the rear passenger side).
Repeat the process for all four wheels, ensuring no air bubbles are present.
Check brake fluid levels and top off as required.

5. Clear Error Codes and Test Drive

Use the OBD-II scanner to clear any stored error codes from the ABS module.
Conduct a test drive to ensure the ABS system is functioning properly and verify that the warning light does not reappear.
