/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.

Key Memory
Whenever one of the FZV keys is used to lock or unlock the
car, the user is identified by the GM. A maximum of four
keys
can be programmed with the Key Memoryfeature. The use of
the personalized key then triggers Car Memory functions
such as heating
I AIC (IHKA) settings or memory seat position
adjustment.
Most programming of Key Memory requires the use of
BMW
scan tools (DISplus, GT1 or MoDiC). However, features such
as
IHKA blower speed and temperature store automatically
without the use of scan tools.
Available Key Memory functions vary based on vehicle equip-
ment. The functions that can be set include:
Automatic locking after start off (vehicle speed)
Selective locking
Heating
1 AJC blower speed, heated or cooled air distribu-
tion, automatic blower setting
Trunk lid soft close (SCA)
< The optional sofl close trunk feature is called SCA. The SCA
actuator is located in the panel below the trunk lid.
1. SCA motor and actuator located behind trunk trim in
rear wall of
trunlc
2. Lower edge of trunlc seal
3. Cam in open position
4. Cam in closed position
The actuator is controlled by a load relay in the General Mod-
ule (GM). The closing cam is mounted on an eccentric that is
driven by the actuator. The cam always turns
180" in the
same direction to open or close the trunk.
