Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area.
Disconnect the sensor connector and check for corrosion.
Use a multimeter to test the sensor's resistance, ensuring it falls within manufacturer specifications.
Replace any faulty sensors.

3. Check ABS Module and Wiring

Inspect the wiring harness connected to the ABS module for fraying or damage.
Ensure all connections are secure and free from corrosion.
If necessary, use a diagnostic tool to run a self-check on the ABS module.

4. Verify Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level and condition; replace if contaminated or low.
Use DOT 3 or DOT 4 brake fluid as specified by the manufacturer.

5. Test Traction Control Switch

Locate the traction control switch inside the vehicle, usually on the dashboard or center console.
Test the switch's functionality using a multimeter; ensure it opens and closes properly.
Replace the switch if it is defective.
