Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical shock during repairs.
Gather necessary tools and parts.

2. Inspect Wheel Speed Sensors

Remove the wheel for access to the wheel speed sensor.
Clean any dirt or debris from the sensor and surrounding area.
Use a multimeter to check the sensor's resistance, ensuring it falls within manufacturer specifications.
If faulty, replace the wheel speed sensor.

3. Examine ABS Module

Locate the ABS module and inspect electrical connectors for corrosion or loose connections.
If necessary, clean the connectors and ensure a secure fit.
If the ABS module is faulty, replace it according to the manufacturer's specifications.

4. Check Brake System

Inspect the brake pads for wear and ensure they are not excessively worn.
Verify that the brake fluid level is adequate and replace it if it is contaminated.
If brake pads are worn, replace them with OEM parts.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Clear any error codes using the OBD-II scanner and take the car for a test drive to confirm the traction control system operates correctly.
