Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Replace Faulty Wheel Speed Sensor (if applicable)

Locate the wheel speed sensor:
- Refer to the vehicle's service manual for the exact location.
Remove the wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Disconnect the sensor wiring:
- Carefully unplug the sensor connector.
Remove the old sensor:
- Unscrew the sensor from its mounting point using the appropriate socket.
Install the new sensor:
- Position the new sensor into place and tighten it to manufacturer specifications (typically around 8-10 ft-lbs).
Reconnect the sensor wiring:
- Plug in the connector securely.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir:
- Check the owner's manual for its location.
Inspect fluid level:
- If low, remove the cap and add brake fluid (DOT 3 or DOT 4 as per specifications) until it reaches the 'full' mark.
Check for leaks:
- Inspect brake lines and connections for signs of leaks.

4. Reconnect Battery

Reconnect the battery terminals (positive first, then negative) and ensure they are tight.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored error codes related to the stability control system.
