Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Repair Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any protective covers if necessary.
Disconnect the electrical connector from the sensor.
Inspect the sensor for cracks or debris; clean or replace as needed.
Reconnect the sensor and secure it in place.

3. Check ABS Module Connection

Locate the ABS module, typically near the brake master cylinder.
Inspect the connector and wiring for any visible damage.
If necessary, disconnect the ABS module and clean the terminals with electrical contact cleaner.
Reconnect the module securely.

4. Brake Fluid and System Inspection

Check the brake fluid reservoir level; top off with recommended brake fluid if low.
Inspect brake lines for any leakage or damage.
If leaks are found, replace damaged lines or components as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any fault codes related to the traction control system.

6. Test Drive

Start the vehicle and perform a test drive.
Monitor the dashboard for the traction control light; ensure it remains off during regular driving conditions.
