Solution

1. Preparation

Gather the necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect Wheel Speed Sensors

Remove the wheel for better access.
Check the sensor for any cracks or physical damage.
Clean the sensor and surrounding area to remove debris.
Reconnect any loose wiring and ensure the sensor is securely mounted.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect fluid level; if low, top off with the manufacturer-recommended brake fluid.
If the fluid is contaminated, perform a full brake fluid replacement.

4. Test Traction Control Switch

Locate the traction control button on the dashboard.
Use a multimeter to test for continuity when the switch is pressed.
Replace the switch if it fails the continuity test.

5. Inspect ABS Module and Wiring

Locate the ABS module, usually near the brake master cylinder.
Inspect the module for signs of moisture or corrosion.
Check wiring harness connections for any signs of wear or damage.
Repair or replace any faulty components as necessary.
