Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench.
Gather necessary replacement parts based on diagnostic results.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Resetting the System

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Access the stability control system in the scanner and clear any stored fault codes.
Turn the ignition off and disconnect the scanner.

3. Inspecting and Replacing Wheel Speed Sensors

Raise the vehicle using jack stands and remove the front or rear wheels as needed.
Locate the wheel speed sensors attached to the wheel hub.
Disconnect the wiring harness from the sensor.
Remove the sensor using a socket, noting the mounting torque specification (usually around 8-10 Nm).
Inspect the sensor for any physical damage; replace if necessary with a new sensor.
Reinstall the new sensor, torque it to specification, and reconnect the wiring harness.

4. Checking the Steering Angle Sensor

Locate the steering angle sensor, typically found on the steering column.
Disconnect the battery (negative terminal) to ensure safety.
Remove any covers to access the sensor.
Check for proper alignment; it may require calibration if the steering wheel is off-center.
If necessary, replace the steering angle sensor with a new one.
Reconnect the battery and ensure all connections are secure.

5. Finalizing the Repair

Reinstall the wheels and lower the vehicle.
Start the vehicle and check if the stability control light is still illuminated.
Take the vehicle for a short test drive to ensure the system operates correctly.
