Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface with the steering wheel in the straight-ahead position.

2. Remove the Steering Wheel

Remove the airbag module from the steering wheel (follow manufacturer safety procedures).
Unscrew the central nut securing the steering wheel (use a torque wrench).
Carefully pull the steering wheel off while ensuring no wires are damaged.

3. Replace or Repair the Steering Angle Sensor

Locate the steering angle sensor, usually mounted on the steering column.
Disconnect the electrical connector from the sensor.
If replacing, remove the sensor by unscrewing it from its mounting (note any torque specifications).
Install the new or repaired sensor by reversing the removal steps and ensuring it is properly aligned.

4. Reinstall the Steering Wheel

Align the steering wheel to the straight position.
Reattach the steering wheel, securing it with the central nut to the specified torque.
Reconnect the airbag module and ensure all connectors are securely fastened.

5. Calibration

Reconnect the negative battery terminal.
Use an OBD-II scanner to reset and recalibrate the steering angle sensor according to the manufacturer’s instructions.
