NOTE-
The Key Memory function of the GM responds to the ley
identification number of each key If the keys are not initial-
ized
in the same orderprior to initialization, the ley memory
functions activated by the
l(eys will not be assigned correctly.
Always initialize the keys
in the same order.
es momentarily.
Release both buttons. GM immediately locks and unlocits
doors to signal successful initialization.
Remote system coding
* Initialize remaining lteys, repeating steps above.
The E39 remote entry system uses coded signals for security
purposes. The code signal sent by the transmitter is changed
every time the vehicle is lockedlunlocked with the transmitter.
A separate code signal is used for each transmitter that is ini-
tialized to the system. This allows for each transmitterto oper-
ate independently of the others.
Due to the changing of the code each time the buttons are de-
pressed, the system allows for a
lacit of synchronization be-
tween the transmitter and receiver. This would occur
if the
buttons on the transmitter are pressed inadvertently.
Up to
100 erroneous actuations of the transmitter are auto-
matically corrected
forby the control module. If more than 100
actuations are present, the operator need only to press the
button a second time to restore system operation.

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.
