Calibrating convertible top
Calibration of the Cabriolet convertible top and the convertible top compartment lid is carried out via the diagnosis interface in the car and the PIWIS Tester. The respective potentiometer values (convertible top and convertible top compartment lid) are established during calibration. If the potentiometer values are plausible, the values are stored. The calibration values can then be calculated as a percentage by the convertible top control module from the potentiometer values.

1. Connect the Porsche System Tester to the diagnostic socket.
2. Switch on ignition.
3. Select the Convertible top menu item, Drive links, and select theCalibrate menu item in the command line which then appears.
4. Start calibration with the F8 key. Calibration can be started irrespective of whether the convertible top position is open or closed. The latching hook in roof frame 1 does not close during calibration.

The latching hook in roof frame 1 does not close during calibration.

Calibration is not counted as actuation. Calibration can be interrupted at any time with the F8 key on the Tester.
