Function Of Individual Components

Components 1 - 15:

1. Control module
Processes the incoming signals and, if necessary, triggers an alarm.

1a. Control unit fuse
A 15 A fuse is located in the control unit between both slots which protects the control unit from short circuit at the output. If this fuse blows, the control unit functions are no longer available.

2. Alarm readiness light

Function 1
Display of the locking state.

Function 2
Display of the operating state of the alarm system.

Six display types are possible:
- Normal flashing (0.5 Hz)
- Double flashing (0.5 Hz)
- Rapid flashing (2.0 Hz)
- Rapid flashing (10.0 Hz)
- On
- Off

3. Central locking button
The doors can be locked and unlocked with the central locking button.

4. Door lock module
The door lock modules (driver's/passenger's door) each contain 5 micro switches:
- 1 switch for priming the system (ground pulse).
- 1 switch for deactivating the system (ground pulse).
- 1 switch for recognizing door closed.
- 1 switch for recognizing door locked.
- 1 switch for recognizing door secured.

5. Switch, rear lid
The switch connects ground to the control module.

6. Switch, front lid
The switch connects ground to the control module.

7. Switch, oddments tray
The switch connects ground to the control module when the oddments tray is opened.

8. Passenger compartment monitoring sensor
The passenger compartment monitoring sensor connects ground to the control module when movement is detected in the vehicle.

9. Radio alarm contact
The alarm contact on the radio mounting frame connects ground to the control module when the radio is removed from the frame.

10. Switch, convertible top compartment cover
The switch connects ground to the control module.

11. Switch, convertible top closed
The switch connects ground to the control module.

12. Alarm horn
In the event of an alarm, the horn is supplied with positive potential by the control module.


NOTE: If the positive supply for the alarm horn is interrupted, the visual alarm is triggered via the direction indicator lights and the interior lights.


13. Signal converter
The signal converter obtains the transponder code from the signals sent by the transponder, and then sends this code on to the alarm control module. With the help of Porsche System Tester 2 the transponder of a key which is inserted in the ignition can be adapted to one of the 4 memory locations for transponders. The first time the transponder is adapted, its Secret Key is programmed.
The Secret Key of the transponder can no longer be overwritten, i.e. a programmed and adapted transponder is permanently assigned to one vehicle.

14. Transponder coil
The transponder coil reads the transponder code out of the transponder.

15. Sliding roof
The sliding roof is not alarm-protected, i.e. opening the sliding roof by force will not trigger an alarm.
