Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, steering wheel puller
Disconnect the negative battery terminal to prevent electrical shorts and ensure safety.

2. Remove the Steering Wheel

Remove the airbag by unscrewing the retaining screws located on the back of the steering wheel.
Disconnect the airbag connector carefully.
Use a steering wheel puller to remove the steering wheel from the column.
Mark the position of the steering wheel on the column for reinstallation.

3. Remove the Steering Angle Sensor

Locate the steering angle sensor mounted on the steering column.
Disconnect the electrical connector from the sensor.
Remove the mounting screws from the sensor using a socket set.
Carefully slide the sensor off the steering column.

4. Install New Steering Angle Sensor

Position the new steering angle sensor onto the steering column, ensuring it aligns with the marked position.
Secure the sensor with the mounting screws and tighten them to the manufacturer’s specifications (typically around 7-10 Nm).
Reconnect the electrical connector to the new sensor.

5. Reinstall the Steering Wheel

Align the steering wheel with the mark made earlier and press it back onto the steering column.
Reconnect the airbag connector and secure the airbag to the steering wheel.
Reconnect the negative battery terminal.

6. Calibration

Start the vehicle and use the OBD-II scanner to check for any remaining error codes.
Perform a steering angle sensor calibration using the scanner, following the manufacturer's instructions.
