Solution

1. Preparation

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

2. Address Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel corresponding to the affected sensor.
Locate the wheel speed sensor and disconnect the electrical connector.
Use a multimeter to test the sensor's resistance. Replace if it is out of specification.
Clean the sensor mounting area and reinstall the sensor. Reconnect the electrical connector.

3. Inspect and Replace Brake Fluid

Tools Required: Brake fluid tester, turkey baster, brake fluid
Remove the brake fluid reservoir cap.
Use a turkey baster to extract old brake fluid from the reservoir.
Check the condition of the brake fluid with a tester; replace if moisture content is high.
Refill the reservoir with manufacturer-approved brake fluid to the correct level.

4. Test and Replace Traction Control Switch

Tools Required: Screwdriver, replacement switch
Locate the traction control switch on the dashboard.
Remove the switch assembly using a screwdriver.
Disconnect the wiring harness and test the switch for continuity with a multimeter.
If faulty, replace it with a new switch and reinstall the assembly.

5. Reconnect Battery and Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the traction control warning light remains illuminated.
