CENTRAL LOCKING BUTTON
The central lock button in the center console
provides a momentary ground input signal to the
GM.
• This input initiates a single lock for each door
and the trunk.
• The fuel filler flap remains unlocked for
refueling purposes.
• If a door is manually opened while centrally
locked, the remaining doors stay locked.
The opened door can be re-locked when closed by manually locking or pushing the central
button twice. This allows the locks of the remaining doors to be re-synchronized again.
As an additional safety feature, the central lock button input also unlocks a double locked
system. Pressing the button returns the system to central lock (single) position, allowing
the doors to be opened when the interior door handles are opened twice. This feature was
also added to other ZKE systems during the 1999 model year.
CRASH SIGNALLING
The Multiple Restraint System (MRS III) provides a switched signal to the GM in the event
of an accident. The signal is an output function of the MRS control module and becomes
active when MRS determines a crash has occurred.
When active, the GM unlocks the door lock actuators, switches on the interior lights and
signals the LCM III via the K bus to activate the hazard warning flashers.
Once the crash signal is active, the GM will not respond to lock requests from the system
until the ignition switch is cycled or a front door is opened.

Car Memory / Key Memory
The Car/Key Memory feature provides the flexibility of allowing the owner to customize cer-
tain functions of select vehicle systems and automatically identifies users of the vehicle by
a key identification signal provided by the remote keyless entry system (FZV).
Car & Key memory is marketed as a combined feature but is actually two separate func-
tions of the select vehicle control systems.
Car Memory: The owner is provided with a list of available system functions that can be
customized to their liking. Prior to delivery, the DIS or MoDiC is used to encode the
owner’s chosen selections into the appropriate control modules.
These choices become a permanent function of the control module and can only be
changed by re-encoding with the DIS or MoDiC at a BMW Center.
This feature has been available for some time via the ZCS Conversion Feature but has never
been fully utilized or officially presented to the vehicle owner as a feature of their vehicle.

INTERIOR LIGHTING
The GM controls the interior lighting automatically with the status change of several moni-
tored inputs. The lighting can also be manually controlled using the interior light switch.
COMPONENTS
DOOR CONTACTS: The door lock actuators contain a hall effect sensor for the purpose
of monitoring door open/closed status (hall sensor 3 in the driver's door actuator). The hall
effect sensor is located directly behind the rotary latch plate encased in the actuator. The
sensor is activated by the rotary latch plate's position. A change in current flow informs the
General module when a door is opened or closed.
Front seat interior/map light unit: The overhead
front seat interior/map light unit contains a single
main interior light. The light is controlled by the GM
automatically or by momentarily pressing interior
light switch located on the light assembly. The
switch provides a momentary ground signal that the
GM recognizes as a request to either turn the light
on (if off) or turn the light off (if on).
If the switch is held for more than 3 seconds, the GM interprets the continuous ground sig-
nal as a request to turn the interior light circuit off for the Workshop Mode as on previous
systems. The workshop mode is stored in memory and will not come back on even if the
GM is removed from it's power supply and reconnected. The switch must be pressed to
turn the lights back on.
There are two reading/map lights also located in the assembly. Each map light is mechan-
ically controlled by depressing it's corresponding on/off switch. The power supply for the
map lights is supplied by the GM through the Consumer Cut Off circuit.
Rear seat interior light unit:
In the center headliner is an additional interior/reading light unit. This unit contains an inte-
rior light that is controlled with the front interior light and a mechanically switched reading
light on the consumer cut off circuit.
Front footwell lights:
In each front footwell, there is also a courtesy light. These lights are only operated when
the GM provides power to the interior lighting circuit.

AUTOMATIC CONTROL FUNCTION
The GM provides 12 volts (linear application providing soft on feature) to the interior light-
ing circuit when the one of the following input signal statuses change:
• Door contact hall sensor active (door opened)
• An Unlock request from the driver's door key lock hall sensors are received. This only
occurs if the ignition switch is off.
• An Unlock request is from the FZV keyless entry system is received via the K bus. This
only occurs if the ignition switch is off as well.
• The ignition switch is switched off and the vehicle exterior lights (LCM III) have been on
for a minimum of 2 minutes prior. This information is provided to the GM via the K bus.
• Active crash signal from the MRS III control module.
• Lock button of FZV key is pressed with the vehicle is already locked (interior search
function).
The GM gradually reduces the full 12 volt power supply (linear reduction providing soft off)
until the lights are off when the following input signal statuses change:
• Immediately after the ignition switch is turned to KL R with the driver's door hall sensor
door contact closed.
• When the vehicle is locked (single or double) with the door contacts closed.
• When the vehicle door contacts are closed. The lights remain on for 20 seconds and
then go to soft off.
• After the interior search function is activated, the lights will automatically turn off (soft off)
after 8 seconds.
• After 16 minutes with a door contact active (open door) and the key off, the lights are
switched off (consumer cutoff function).
• The component activation function of the DIS also has the ability to switch the lights.
The Interior lighting output circuit of the GM is approximately 3.5 amps with all lights on.

INTERIOR PROTECTION (UIS)
The UIS monitors the vehicle interior for motion through ultrasonic sound waves. The UIS
is a combined transmitter and receiver.
The X5 UIS sensor is incorporated into the
rear seat interior light trim cover. It is a two
piece unit with cable connection to the rear
transmitter/receiver.
The UIS and trim panel are clearly identified
with arrows indicating forward mounting
direction.
Due to the design of the vehicles interior,
the sensor is uni-directional and must be
installed in the proper direction to ensure
proper operation of the system (trim cover
ensures directional installation).
Every time the DWA system is armed (signal STDWA), the sensor adapts to what ever
objects might be stationary in the interior.
The sensor emits ultra sonic waves in a pro-
grammed timed cycle. It receives echos of
the emitted waves.
The UIS amplifies the received sound wave
signals and compares them with the trans-
mitted waves. The UIS also checks the
incoming echos for background hiss (wind
noise through a partially open window) and
adapts for this.
• If the echos are consistently similar, no movement is detected,
• If the echos are altered, (inconsistent), the UIS determines motion in the interior com-
partment.
If motion is detected, the UIS changes to a constant cycle and the echo is compared again.
If the inconsistency is still present the UIS sends the activate siren signal (INRS) to the GM.
As with the tilt sensor, the UIS is also switched OFF when the vehicle is locked two times
within ten seconds. This allows the sensor to be switched OFF for transportation purpos-
es.

DWA ARMING/DISARMING
• The DWA is armed every time the vehicle is locked from the outside with the door lock
cylinder or FZV key.
• The LED in the rear view mirror flashes as an acknowledgment along with the exterior
lights and a momentary chirp from the siren.
• The GM monitors all required input signals for closed status (door closed, tailgate
closed, etc.) The inputs must be in a closed status for a minimum of 3 seconds for the
GM to include them as an activation component. If after 3 seconds any input signal not
in the closed status is excluded (this is acknowledged by the DWA LED) preventing false
alarm activation's.
• If the DWA is armed a second time within 10 seconds, the tilt sensor and interior pro-
tection sensor are also excluded as alarm activation components. This function is use-
ful if the vehicle is transported on a train or flat bed truck to prevent false alarm activa-
tion's.
• While armed the tailgate can be opened with out the alarm being triggered as follows:
- If opened with the tailgate remote button via the FZV, the GM prevents the alarm
from activating. (This feature is customizable under the Car Memory function).
- If opened with the key at the tailgate lock cylinder the tailgate key position switch
signals the GM and in the same manner prevents the alarm from activating.
In either case, when the tailgate is returned to the closed position, it is no longer con-
sidered as an activation signal.
Panic Mode Operation: When the tailgate button is pressed and held, the GM is signaled
to activate the siren for the Panic Mode. The panic mode will function with either an armed
or disarmed DWA system.
EMERGENCY DISARMING
Emergency disarming occurs automatically if a key is used to turn the ignition switch on and
the EWS III accepts it. The EWS III signals the GM to unlock the doors and deactivate the
DWA.
