Antitheft and Alarm Systems: Description and Operation

Antitheft Alarm System (DWA)

The function of the anti-theft alarm system (DWA) is integrated in the roof function centre (FZD) control unit.

DWA alarm activations
The last 10 alarm activations are stored in the DWA alarm memory.

Customer complaint - false alarm
Procedure in the event of the customer complaint 'false alarm':
- Read out the DWA alarm memory (test module 'DWA activations').
- Check all the sensors that caused an alarm.
- During the check, take account of the fact that a mechanical fault can also be responsible for a false alarm (example: engine compartment lid, door or luggage compartment lid does not close properly).
