In order to carry out servicing work the alarm siren must be switched off before the work is commenced. To switch it off, insert the vehicle key with valid transponder into the ignition lock and rotate to actuate the buzzer contact. Components can be removed with triggering the alarm as long as the vehicle key remains inserted.

Function display and audible checkback

The operating state of the central locking system is fed back via the output "Door locked" and by corresponding activation of the interior light (signals 1 to 3). The operating state of the alarm system is also indicated during the inactive period by the alarm readiness display (display types 1 to 6). It is indicated exclusively by the alarm readiness display following expiry of the inactive period. Displayed system faults are always current faults. Previous system faults entered in the status memory have no influence on the function display.

On time 1,2 = 100 ms Off time 1 = 200 ms Off time 2 = 1700 ms

Display type 3 (rapid flashing)

Requirement: alarm system primed no active alarm inputs

Duration: inactive period, then Display type 1

LED flashes with a frequency of 2 Hz On time = 100 ms Off time = 400 ms

Display type 4 (rapid flashing)

In addition, the checkback of faults and of the standard status is performed with signal 3 at the interior light output. An audible checkback via the alarm horn output also takes place at the alarm control module, together with a visual checkback via the outputs for the direction indicator lights.

The following signals are defined: Signal 1

The outputs are triggered once On time = 50 ms

Signal 2

The outputs are triggered twice On time 1,2 = 50 ms Off time = 200 ms

Signal 3

The outputs are triggered once On time = 2500 ms

These functions can be switched on and off with the Porsche System Tester 2, depending on the national variants. The times are freely programmable.
