DWA Arming Sequence

Immediately after arming  the emergency siren is armed and monitors its voltage supply. The DWA commences line monitoring on the local DWA bus.

3 s after arming  each of the door and tailgate contacts to be monitored is included in the alarm table. Faulty contacts are evaluated as closed, but are not included in the alarm table. The tire pressure monitoring system is included in the alarm table.

3 s after centrally locking  the vehicle or after locking the last door or tailgate the referencing phase of the tilt sensor commences. During this period, the ultrasonic sensors are verified for signal plausibility. The sensitivity level is set in accordance with the window and slide/tilt sunroof positions.

30 s after locking  the last door or tailgate the tilt sensor is included in the alarm table upon expiration of its referencing period.

If no acknowledgement message is received from the tilt sensor within 60 s of arming, this sensor is deleted. If at least one input signal is not in idle state or if a sensor is defective, this is signalled by the flashing LED.

If the emergency siren does not acknowledge the "arm" command, this is also indicated by the LED.
