to be used
only once. When removing trim that is held in place with clips,
it is a good idea to have spare clips on hand before beginning
the job.
WARNING-
Special precautions must be observed when servicing the
BMWSupplementai Restraint System (SRS). Serious inju-
ry may result if system service is attempted by persons un-
familiar with the BMW
SRS and its approved service
procedures. BMW
speciiies that all inspection and service
should be performed by an authorized BMW
dealer.
Before performing any work involving airbags, discon-
nect the negative
() battery cable. See 721 Airbag
System (SRS).
Airbags contain a back-uppowersupply within the SRS
control module. A
5 second discharge period should be
allowed after the battery cable has been disconnected.
CAUTION-
* When working on electrical switclies or lights, always dis-
connect the negative
(-) cable from the battery and insu-
late the cable end to prevent accidental reconnection.
a Prior to disconnecting the battery, read the battery dis-
connection cautions given in
W1 General Warnings
and Cautions.
To prevent marring the trim when working on interior
components, work with plastic prying

/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.
