/Central Locking and Anti-Theft
This section covers repair information for door, trunk and car-
go compartment locks, central locking, electronic
immob~liza-
tion (EWS) and anti-theft alarm (DWA).
€39 cars are equipped with sophisticated self-diagnostic elec-
trical systems. When experiencing malfunctions relating to
central locking. EWS or anti-theft systems, start the diagnosis
process using the
BMW service tester DIS, GT 1, MoDiC or
equivalent scan tool. An advanced diagnostic scan tool can
usually pinpoint electrical faults quickly and safely.
Additional electrical information can be found in:
610 Electrical Component Locations
ELE Electrical Wiring Diagrams
Central locking in E39 vehicles controls the door
locks, trunk
or tailgate lock and fuel filler flap lock. The control module for
the Central Body Electronics system (ZKE
Ill), lknown as the
General Module (GM
Ill), controls central locking.
ZKE
Ill manages the following central locking related func-
tions:
Central locking
* Keyless entry
Key memory
Power trunk release
Electric opening of tailgate
DWA alarm system
Diagnosis
General Module
4 The General Module (GM) (arrow) is responsible for the op-
eration of central body electronics. The GM is located behind
the glove compartment.
Based on input information, the GM uses internal transistors
to switch current flow (providing voltage or ground) through
circuits and actuators. Actuators are the final controlling de-
vices used by GM to operate or control various output func-
tions such as relays and motors.
The accompanying schematic, Central locking inputs and
outputs, illustrates the GM central locking system.

I Central Locking and Anti-Theft
Driver's door lock
The
lock/unlock signals are sent as input to the door module
from two microswitches on the lockcylinder. The driver's door
module carries out the locking
/ unlocking functions of the
driver's door through its final stage control.
The signal to lock the remaining doors, trunk or tailgate and
fuel flap is sent over the P-Bus to the GM and the passenger
door module. Activation of the passengers door
loclt is carried
out by the passenger door module. The rear doors, trunlt or
tailgate and fuel flap are
locked by the f~nal stage in the GM.
When
locked from the outside, all doors are set to the double
lock position and the GM will not carry out any unlock com-
mands from the central
loclc button or remote trunk release
button.
Selective unlocking
When unlocking with the key or the remote transmitter, the
first unloclcrequestwill only unlock the driver'sdoor. A second
unlock request will unlock the remaining doors, trunk or tail-
gate and fuel flap.
Trunk locking
I
The vehicle can be locked/unlocked from the trunlc loclc cylin-
der. The GM locks the trunk or tailgate, rear doors and fuel fill-
er. The locking command is passed over the P-Bus to the
respective door modules to lock the driver's and passengers
doors.
Locking the trunk and removing the key in the
hor~zontal posi-
tion will set the valet lock and prevent opening of the trunlt
with the central locking system.
Central locking switch
-
< The central locking master control switch (arrow) is located
in the center console behind the shifter.
The central locking button will only single
loclt the doors
and trunk. The filler flap remains unloclted for refueling pur-
poses.
If a door is opened from inside while centrally locked, the
remaining doors remain locked.
The open door can be relocked, when closed, by manually
locking or pressing the central locking button twice. This
synchronizes the door
locks.

< The remote trunk button (arrow) is located in the lefl lticlc

- The trunk can be opened from this remote release when the
doors are locked from the central locking button. The
trunk
remote button is disabled when the trunkis loclted in the valet
position or when a speed signal of
4 mph is present at the
GM.
Remote entry (FZV)
< The €39 remote (keyless) entry system (FZV) uses a tiny ra-
dio transmitter in the vehicle key to
lock and unlock the doors
and the trunk by remote control. There are a number of other
features incorporated in FZV:
Locltinglunloclting of fuel filler lid
Selective unlocking of driver's door (as with key in lock)
Armingldisarming of DWA alarm system
Remote unlocking of
trunk lid or tailgate
Comfort opening of windows and sunroof
* Interior lighting activation
Panic mode alarm activation
* Models to 1999: Key incorporates LED. LED informs oper-
ator that an FZV signal is being transmitted. LED is also
useful indicator of key initialization status and lkey self-test.
Keys delivered with four different colored labels. This is
helpful to differentiate FZV keys during initialization,
pre.
venting possibility of misassigning key ID which would
change coded Key Memory functions.

/Central Locking and Anti-Theft
The General Module (GM) is connected to the FZV receiver
module (in left rear roof pillar) via K-Bus. Locking and unlock-
ing of doors, trunk or tailgate and convenience closing is car-
ried out by the GM subsystem controlling the door lock,
window and sunroof modules.
The accompanying schematic, Remote entry
(FZV) inputs
and outputs, illustrates the GM remote entry subsystem.

SCA operation
Three microswitches are used to operate trunk latching sys-
tem.
Microswitch mounted on lock cylinder. Pushing lock cylin-
der in will signal GM to activate actuator and open trunk.
Q Microswitch in actuator signals GM when trunlc has re-
leased. Actuator shuts off.
When closing trunk, third microswitch (on trunk latch) sig-
nals GM to activate actuator. Cam turns to pull lid closed.
Foroverload protection,
ON duration of actuator is limited to a
max.
5 seconds.
Emergency opening of trunk is provided by a mechanical link
from the lockcylinder.
If the trunlc has been opened by the
emergency release, it can be
reclosed as a conventional lid
with normal pressure.
Tailgate and rear window locks
The Sport Wagon tailgate can be opened from:
0 Remote lkey (FZV)
Interior tailgate release button at driver's lkick panel
