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) and exclusively by the alarm readiness display following expiration 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.

LED flashes with a frequency of 0.5 Hz
On time = 100 ms
Off time = 1900 ms


Display type 2 (double flashing)
LED flashes with a frequency of 0.5 Hz
On time 1,2 = 100 ms
Off time 1 = 200 ms
Off time 2 = 1700 ms


Display type 3 (rapid flashing)
LED flashes with a frequency of 2 Hz
On time = 100 ms
Off time = 100 ms


Display type 4 (rapid flashing)

Off time = 50 ms


Display type 5 (on)

In addition, the checkback of faults and of statuses deviating from 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 center, 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.
