Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, and brake cleaner.

2. Address Fault Codes

Use the OBD-II scanner to read and document any fault codes related to the traction control system.
Clear the fault codes and see if they reappear after a test drive.

3. Inspect and Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Remove the sensor from its mounting location using the appropriate socket.
Clean the sensor mounting area with a wire brush and brake cleaner.
Install the new wheel speed sensor and reconnect the wiring harness.
Reinstall the wheel and lower the vehicle.

4. Check and Repair Wiring

Inspect the wiring harness for any signs of damage or corrosion.
Use a multimeter to check for continuity in the wiring.
Repair or replace any damaged wiring or connectors.

5. Brake Fluid Check

Check the brake fluid reservoir for proper level; add fluid if necessary.
If fluid is contaminated, flush the brake system and replace with manufacturer-recommended brake fluid.

6. Final Assembly and Testing

Reconnect the battery.
Start the vehicle and check for any warning lights.
