l~entral Locking and Anti-Theft
ANTI-THEFT SYSTEM (DWA)
When the anti-then system (DWA) is armed, the doors, hood,
windows, trunk lid or tailgate are monitored against forcible
entry by switches and sensors. The vehicle is protected
against being jacked up or towed away by a tilt sensor.
The control electronics for DWA are integrated in the General
Module (GM). In addition to the control electronics, the sys-
tem includes the following components.
* DWA horn
DWA LED indicator
- Tilt sensor
- Monitoring switches and sensors
The system can be armed or disarmed from the driver's door
lock,
trunklid lock, tailgate lockorthe remote transmitter (FZV
Itey). When armed, the alarm horn
soundsfor30seconds and
the low beam headlights and turn signals flash for
5 minutes.
The electronic immobilizer (EWS) is also activated when
DWA is activated.
The alarm is switched off immediately if key is inserted in door
loclt or FZV key button is used.
DWA LED Status
The DWA status LED is located in the rear view mirror (ar-
row). When DWA is armed, the LED flashes slowly to indi-
cate armed status.
The LED and exterior lights flash once and the alarm horn
sounds when the system is successfully armed ordisarmed.
The LED will continue to flash slowly denoting the armed sta-
tus. If any monitored input is not closed when the system is
armed, the LED will flash rapidly for
10 seconds to indicate
the fault.
Tilt sensor
-
4 The tilt sensor, located on the left side of trunlt or cargo com- -
partment, consists of a conductive liquid chamber, a proces-
sor board and metal probes. The probes are submersed in
the liquid and produce a resistance value dependent on the
tilt of the sensor (angle of the vehicle). This resistance be-
comes the reference value when the DWA system is armed.
