Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area.
Check the wiring harness for any signs of wear or damage.
Use a multimeter to test the sensor resistance (should be within manufacturer specifications).
Replace any faulty sensors as necessary.

3. Check Brake System

Inspect brake pads and rotors for wear. Replace if necessary.
Verify that brake fluid levels are correct and there are no leaks.
Check brake lines for any signs of damage or corrosion.

4. Examine ABS Module

Locate the ABS module, typically near the brake master cylinder.
Inspect wiring and connections for corrosion or damage.
Use a diagnostic tool to perform ABS module tests to ensure proper operation.
Replace the ABS module if it fails the diagnostic tests.

5. Reconnect Battery and Reset System

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored codes.
Start the vehicle and check if the traction control light remains off.
