Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, multimeter
Locate the wheel speed sensors at each wheel hub.
Remove the sensors using the socket set.
Clean the sensor tips and mounting surfaces with a brush.
Inspect the wiring and connectors for damage. Repair or replace as needed.
Reinstall the sensors and secure them properly.

3. Check and Replace Brake Fluid (if necessary)

Tools Required: Brake fluid tester, funnel, container for old fluid
Remove the brake fluid reservoir cap.
Use the brake fluid tester to check the fluid condition; replace if contaminated or low.
If necessary, siphon out the old fluid and refill with DOT 3 or DOT 4 brake fluid.
Replace the reservoir cap securely.

4. Inspect the Traction Control Switch

Tools Required: Screwdriver set, multimeter
Locate the traction control switch (usually on the dashboard).
Remove the switch and visually inspect for damage or corrosion.
Use a multimeter to test the switch functionality. Replace if defective.

5. Reconnect Battery and Clear Codes

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