Information
- The steering-angle sensor must be recalibrated on the measuring platform following repairs to or work on the chassis/steering or if the steering-angle sensor/steering column switch is replaced .
- Calibration includes initialization .
- In order to calibrate the steering-angle sensor correctly, the vehicle must be on the measuring platform, the wheel alignment values must be correct and the steering must be in the straight-ahead position .
- Calibrate the steering-angle sensor by selecting >>Steering wheel electronics>>Maintenance/repairs>>Steering-angle sensor calibration<< in the PIWIS Tester II control unit overview .
The steering-angle sensor must be calibrated by selecting the relevant menu on the Porsche System Tester under the specified test conditions:
- The chassis is adjusted according to Porsche specifications.
- Switch on ignition.
- Wheels in straight-ahead position and steering wheel horizontal.
- In the straight-ahead position, the steering wheel may be turned by max. ± 2.0° from the horizontal position (steering center position).
- Enter the security code under the >>Calibrate<< menu in the Porsche System Tester.
- Turn the steering wheel out of the straight-ahead position (approx. 6° to the left/right) in accordance with the instructions on the Porsche System Tester. Turn the wheels back to the straight-ahead position and follow the instructions on the Porsche System Tester.
- Following successful calibration, the stored fault code is erased from the fault memory. The PSM indicator light in the instrument cluster goes out.
