Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety while working on the electrical components.

2. Check and Replace Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the wheel if necessary to access the sensor.
Disconnect the electrical connector from the sensor.
Remove the sensor retaining bolt and gently pull the sensor out.
Inspect the old sensor for damage; replace it with a new one if necessary.
Reinstall the new sensor, securing it with the retaining bolt and reconnecting the electrical connector.
Repeat this process for each wheel if multiple sensors are faulty.

3. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the appropriate brake fluid type as specified in the owner's manual.
Ensure there are no leaks in the brake lines or around the master cylinder.

4. Tire Inspection and Adjustment

Inspect each tire for proper inflation using a tire pressure gauge.
Inflate tires to the manufacturer’s recommended pressure if necessary.
Check for uneven wear or damage to the tires; replace if needed.

5. Reconnect Battery and Clear Error Codes

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