Solution

1. Preparation

Gather necessary tools: OBD-II scanner compatible with Tesla, torque wrench, and a flathead screwdriver.
Ensure the vehicle is on a level surface and the wheels are straight.
Turn off the ignition and disconnect the 12V battery to prevent any electrical shorts.

2. Access the Steering Angle Sensor

Remove the lower dash panel beneath the steering column using the flathead screwdriver.
Locate the steering angle sensor, which is typically mounted on the steering column.

3. Adjust the Steering Angle Sensor

Disconnect the wiring harness from the steering angle sensor.
Use the OBD-II scanner to navigate to the steering angle sensor calibration menu.
Follow the prompts to reset or recalibrate the sensor. This may involve turning the steering wheel fully left and then fully right.

4. Reconnect and Test

Reconnect the wiring harness to the steering angle sensor.
Reattach the lower dash panel securely.
Reconnect the 12V battery and turn on the ignition.
Use the OBD-II scanner to confirm that the sensor is reading correctly and that any previous error codes are cleared.
