Calibrating Convertible Top

Calibrating Convertible Top

Calibration of the Cabriolet convertible top and the convertible top compartment lid is carried out with the Porsche System Tester 2 diagnosis. 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.

The following preconditions must be met in order to enable successful calibration.

1. The convertible-top latch must be repaired (after an emergency operation).
2. The convertible-top compartment lid drive must be repaired (after an emergency operation).
3. The valve screw of the hydraulic pump must be closed.
4. The parking brake must be engaged.
5. The engine compartment lid must be closed.
6. The potentiometer values of the convertible top and the convertible top compartment lid lie between the nominal values specified. See Diagnosis/troubleshooting convertible top (nominal values). Read out fault memory if necessary and proceed according to Diagnosis/troubleshooting convertible top.
7. The upper microswitches of the left and right rear side section flaps are actuated when the opened convertible top is set down. See under Input signals in the Tester: Bitmap position (left side flap up or right side flap up). Read out fault memory if necessary and proceed according to Diagnosis/troubleshooting convertible top.
8. The lower microswitches of the left and right rear side section flaps are actuated when the convertible top is closed. See under Input signals in the Tester: Bitmap position (left side flap down or right side flap down).
Read out fault memory if necessary and proceed according to Diagnosis/troubleshooting convertible top.
9. The convertible top compartment lid micros-witch must be unlocked when the convertible top compartment lid is open. See under Input signals in the Tester: Bit map position (convertible top compartment lid unlocked).
The microswitch must be locked when the convertible top compartment lid is closed. See under Input signals in the Tester: Bit map position (convertible top compartment lid locked). Read out fault memory if necessary and proceed according to Diagnosis/troubleshooting convertible top.

INFORMATION:
The actuation counter 2 is reset during calibration.
Calibration is not counted as actuation.
Calibration can be interrupted at any time with the Tester F8 key.
