Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris using a soft cloth or brush.
Check the wiring harness for any signs of wear or damage.

3. Check Brake System

Inspect brake pads and rotors for wear; replace if necessary.
Confirm that brake fluid levels are adequate; top off with the manufacturer-recommended fluid.
Bleed the brake lines to remove any air bubbles that may affect performance.

4. Test and Replace Steering Angle Sensor (if faulty)

Using a multimeter, test the steering angle sensor for proper voltage output.
If out of range, remove the steering wheel (following safety precautions), and replace the sensor.
Reinstall the steering wheel, ensuring it is aligned correctly.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes and reset the stability control system.
