Function
The PSE control module (combined) (A37) receives the message "lock vehicle" via the CAN bus. It then activates the inputs for the exterior surface contacts and stop lamp switch.

The alarm inputs, to which the contacts are connected, are activated individually. An input is activated as soon as it has been in the non-actuated state for at least 10 seconds.

When the ATA is active the LED in the interior switch (CL) (S6/1s2) flashes.



 The ATA is not activated when the driver's door is open.

 Activation of the ATA leads to termination of any previous alarm.

 The ATA is activated again automatically when the power supply returns when it was active before separation from the power supply.

 ( only):

If one of the doors or trunk lid is opened and closed again after removing the remote control key, the ATA is activated automatically two minutes after the last locking operation.
