Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.
Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Remove any dirt or debris using a clean cloth or compressed air.
Check the sensor wiring for any visible damage or wear.
If necessary, replace damaged sensors with new ones.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, drain the old fluid from the system and replace it with new fluid.
Bleed the brake system to remove air bubbles.

4. Test and Replace Traction Control Switch

Access the traction control switch inside the vehicle.
Disconnect the switch and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new one.
Reconnect the switch and ensure it is securely mounted.

5. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes that were stored in the system.
Start the vehicle and check if the traction control warning light remains off.
