Solution

1. Preparation

Gather tools and parts. Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Remove the wheel for easier access if necessary.
Locate the wheel speed sensors; these are typically mounted near the brake assembly.
Clean any dirt or debris from the sensors and connectors.
Check the wiring for fraying or breaks. Reconnect any loose connections.

3. Check Brake System

Inspect the brake fluid reservoir and refill with the appropriate brake fluid if low.
Examine brake lines for leaks or damage.
Test the brake pedal for proper feel; sponginess may indicate a problem.

4. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to check for any ABS-related codes.
Perform an ABS self-test if the scanner has that feature.

5. Verify Traction Control Switch

Locate the traction control switch, often found on the dashboard or center console.
Test for continuity using a multimeter while pressing the switch.
Replace the switch if faulty.
