Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensors by unscrewing or unclipping them from their mounts.
Clean the sensors and their mounting areas with electrical cleaner to remove dirt or debris.
Reinstall the sensors securely.

3. Check the Brake Fluid and System

Inspect the brake fluid reservoir; add fluid if low, using the recommended brake fluid type (DOT 3 or DOT 4).
Examine brake lines for leaks or damage.
Check brake pads and rotors for wear that may affect braking performance.

4. Inspect ABS Module

Locate the ABS control module, typically found near the master cylinder or under the hood.
Check all wiring harnesses and connectors for corrosion or loose connections.
If necessary, use a multimeter to test the module's power and ground connections.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and test its continuity with a multimeter.
If defective, replace the switch with a new one.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals, ensuring they are secure.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the traction control light remains off.
