Steering Angle Sensor

The steering angle sensor must be re-initialized after battery is disconnected and connected.

1. Turn steering wheel to straight ahead position.
2. Turn ignition off then on again twice (do not start the engine yet).
3. Start engine.
4. From the straight-ahead position, turn steering wheel about 20 degrees to the left and 20 degrees to the right (past the straight-ahead position).
5. Drive the vehicle straight ahead for at least one second at a speed above 2.5 MPH.
6. The stored fault code in the Porsche Stability Management (PSM) control unit should now be cleared automatically. The PSM indicator light in the instrument cluster should now go out.
