Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Ratchet and socket set, cleaning brush, isopropyl alcohol
Remove the wheel covers or wheels for access to the wheel speed sensors.
Clean the sensors and mounting surfaces using a brush and isopropyl alcohol to remove dirt and debris.
Reinstall the wheel covers or wheels and torque the lug nuts to the manufacturer’s specifications.

3. Check Brake Fluid Level

Tools Required: Brake fluid tester or dipstick
Remove the cap from the brake fluid reservoir.
Inspect the fluid level; it should be at the "MAX" line. If low, add the correct type of brake fluid (typically DOT 3 or DOT 4).
Replace the cap securely.

4. Inspect ABS Module and Wiring

Tools Required: Multimeter
Locate the ABS module under the hood.
Check for any visible signs of damage or loose connections.
Using a multimeter, test the wiring harness for continuity according to the service manual specifications.
Repair or replace any damaged wiring or connectors as necessary.

5. Test Traction Control Button

Tools Required: Multimeter
Remove the panel covering the traction control button.
Use a multimeter to check for continuity when the button is pressed.
If the button is faulty, replace it with a new one.
