Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety.
Allow the vehicle to cool down if it has been running.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove any dirt or debris from the sensor area using a soft brush.
Check the sensor connection and wiring for damage or corrosion; repair if necessary.

3. Replace Faulty Wheel Speed Sensors (if needed)

If any sensors are found to be defective, remove the sensor by unscrewing it from its mounting point.
Install the new wheel speed sensor in reverse order of removal.
Torque the sensor to the manufacturer’s specifications (typically around 5-10 Nm).

4. Check and Calibrate Steering Angle Sensor

Connect a diagnostic tool to the vehicle's OBD-II port.
Access the steering angle sensor settings and follow the calibration procedure outlined in the manufacturer’s service manual.
Ensure the steering angle sensor is correctly calibrated.

5. Verify Brake Fluid Condition

Check the brake fluid reservoir for proper fluid level; add brake fluid if low.
If the fluid appears contaminated or old, perform a brake fluid flush and replace with new fluid (DOT 4 recommended).

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals, ensuring they are secure.
Use the OBD-II scanner to clear any diagnostic trouble codes related to the stability control system.
Perform a test drive to ensure the issue is resolved.
