Solution

1. Preparation

Tools Required: OBD-II scanner, torque wrench, flathead screwdriver, T20 Torx screwdriver.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal and wait at least 10 minutes before proceeding.

2. Access the Steering Angle Sensor

Remove the Airbag:
- Using a T20 Torx screwdriver, remove the screws securing the airbag module to the steering wheel.
- Carefully disconnect the airbag connector and set the airbag aside in a safe location, face up.
Remove the Steering Wheel:
- Mark the position of the steering wheel relative to the steering column using a marker for correct alignment during reinstallation.
- Use a steering wheel puller if necessary, and remove the nut holding the steering wheel in place.
- Carefully pull the steering wheel off the column.

3. Reset the Steering Angle Sensor

Locate the Steering Angle Sensor:
- Find the steering angle sensor, typically located on the steering column under the steering wheel.
Reset the Sensor:
- Reconnect the battery temporarily and turn the ignition on.
- Using the OBD-II scanner, select the option to reset or calibrate the steering angle sensor. Follow the prompts on the scanner.
- Turn the steering wheel fully to the left and then fully to the right to complete the calibration process.
- Turn the ignition off and disconnect the battery again.

4. Reassemble Components

Reinstall the Steering Wheel:
- Align the steering wheel with the marks made earlier and tighten the nut to the manufacturer's specified torque (usually around 35 Nm).
Reinstall the Airbag:
- Reconnect the airbag connector and carefully secure the airbag module back onto the steering wheel, ensuring all screws are tightened.
