61E of the alter-
nator connector. Carefully connect the positive
(+) test lead
to the wire using a piercing test lead end.
Turn ignition key on and check for voltage. Voltage should be
less than 1.5 VDC and charge indicator lamp should light.
- Making sure all test equipment and tools are clear, start en-
gine. Voltage should increase to
8.0 VDC or higher. The
charge indicator light should go out.
If voltage does not increase and system is not charging,
the fault is in alternator.
- If voltage does not increase, but system is charging, inter- - roaate svstem for faults usina an appropriate BMW scan - .. . tool and'reset fault memory.
- If a load tester is not available, a quick alternator output test
can be done by running engine at about 2000 rpm and turn-

/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.

Central Locking and Anti-Theft
DWA alarm
The DWA alarm system is
armedldisarmed when thevehicle
is locked / unlocked from either the door or trunk.
Convenience closing
I opening
The windows and sun roof can be closed or opened by hold-
ing the key in the
loclc I unlock position.
Crash sensor
The crash sensor is located in the left front
kick panel. It func-
tions by unlocking all doors in the event of an accident.
NOTE-
Continuous and repeated locliing / unlocking may cause
timedarrest of
the locliing system. When activated, the timed
arrest lasts for two minutes. The timed arrest does not affect
the crash sensor
unlocliing the doors in case of an accident.
Door locks
The driver's door lock location is the only point outside of the
vehicle where the ltey can mechanically control all of the cen-
tral locking system functions.
4 Door key positions for electrical / manual loclting and
unlocking are:
1. Manual unlock
2. Unlock, DWA disarmed, convenience open
(hold until activated)
3. Neutral position
4. Lock, DWA armed, convenience closing
(hold until activated)
5. Manual lock
The door lock actuators are sealed. self contained units with
no replaceable parts. The
actuators use Hall effect sensors in
place of pin contacts and microswitches to provide DOOR
OPEN
I DOOR CLOSED status signal. Each door lock button
only affects the actuator it controls. There is no effect on the
other doors.
An automatic locking feature activates door locks when a
road speed signal of 4 mph is detected via the K-Bus. The fac-
tory default coding for this feature is OFF, but can be coded
ON for individual users with the Key Memoryfunction. See
Car Memory
1 Key Memory later in this section.

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.
