Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to prevent electrical issues.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors.
Disconnect the wiring harness from each sensor.
Use a multimeter to test for continuity in the sensor wiring.
Clean sensors with an appropriate cleaner if dirt is present.

3. Check ABS Control Module

Locate the ABS control module, typically found near the brake master cylinder.
Inspect the module for any physical damage or corrosion on terminals.
Use a multimeter to check for proper voltage supply to the module.
If damaged, replace the ABS control module with a new unit, ensuring proper connections.

4. Verify Brake System Condition

Check brake fluid levels in the master cylinder; refill if necessary.
Inspect brake lines for leaks or damage.
If leaks are found, replace damaged brake lines and bleed the brake system.

5. Reconnect Battery and Test System

Reconnect the battery terminals securely.
Start the vehicle and observe the traction control light.
Perform a test drive to ensure the traction control system operates correctly without warning lights.
