Body-General
Battery safety terminal
(BST)
4 Starting with 1999 models (9198 production and later), a py-
rotechnic (explosive charge) device automatically discon-
nects the battery positive terminal during impacts. Key
features,
like power windows and door locks, remain opera-
tional.
Security
Electronic immobilization (EWS)
Ignition key transponder signal All
E39 vehicles incorporate an electronic immobilization sys-
tem known as EWS. This svstem uses a wireless comrnuni-
cation link between a transponder chip in the ignition key and
the ring antenna surrounding the ignition switch. The EWS
control module blocks the starting of the vehicle unless the
correct coded ignition key is used.
NOTE-
Electronic immobilization is sometimes referred to as the
driveaway protection system.
Antitheft alarm (DWA)
This is adealer-installed option for which the E39 vehicles are
factory-wired. When armed, the system monitors door
loci(
contacts and trunk and engine hood locks and sounds a siren
if it detects tampering.
E39 interiors have a unique character, with a combination
of
sporty features and innovativedesign. All body versions were
made in a wide choice of interior and exterior colors. New col-
ors with matching leather or leatherette upholstery were intro-
duced for each model year.
Driving
comfort is enhanced by power steering, tilt steering
wheel, height-adjustable front seats, and electrically adjust-
able and heated rear-view mirrors. Inside the car there are
reading lights at four seating positions.

/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.

Trunk lid gap
measurements 4 When installing, or adjusting trunk lid alignment, adjust posi-
tion of trunk
loclc striker with mounting bolts finger tight.
* Check trunk lid loclc operation with lid open.
Adjust trunk lid alignment. See
412 Trunk Lid, Tailgate for
lid adjustment specifications.
NOTE-
Do not lubricate lock or lock striker with grease.
Tailgate lock, emergency release
4 In case of electrical failure, there is an emergency tailgate
loclk release. The release is located in the tailgate behind the
tool door.
- With tool door open, remove access cover and pull to the
right to release tailgate.
ELECTRONIC ~MMOBILIZATION (EWS)
E39 cars are equipped with a passive theft-prevention sys-
tem. The Electronic Immobilization System (EWS) makes it
impossible to
startthe engine using any means other than the
special lkeys furnished with the vehicle.
NOTE-
Replacement EWS control modules or DME control modules
must be electronically aligned to each before the vehicle will
start. This requires the use of the BMW Service Tester
(DIS-
plus, GT1, or MoDiC). Without alignment, the engine will not
crank (for example: swapping a
known good DME control
module into another vehicle for test purposes will result in a
no crank situation).
In the EWS system, the ignition key is embedded with
acom-
puter chip (EEPROM) and coded. The key communicates
with the vehicle using a transponder in the lkey and a ring an-
tenna surrounding the steering lock cylinder. Up to
6 replace-
ment keys are permissible. Only an authorized
BMW dealer
can provide replacement keys.

Central Locking and Anii-Theft
- If the starter engages, the following EWS inputs are function-
ing normally:
Ignition key
Code function
Transmission range switch or clutch position switch
Engine speed sensor
NO JE -
If a vehicle key is lost or stolen, the electronic authorization
for that key
can be cancelled using the BMW scan and di-
agnostic tools
DISplus, GTl or MoDiC.
Force applied to a ley can damage the electronic circuitry
in the key A damaged ley will not start the engine. In that
case, a new key should be purchased and initialized
by an
authorized BMW dealer.

Insert screwdriver through opening in rear of steering
wheel and push against spring tension to release
airbag
unit lock.
Repeat procedure on other side of steering wheel.
Lift off
airbag unit and detach electrical harness connec-
tors.
WARNING-
Store the removedairbag unit with the horn pad facing up.
If stored facing down, accidental deployment could propel
it violently into the air, causing injury.
Once an
airbag is removed, the car must not be driven.
Do not connect the battery with the
airbag disconnect-
ed. A fault code will be stored, setting off the
airbag in-
dicator light Special tools are needed to reset the fault
memory
Once the
airbag unit is installed and all other service
procedures have been completed, start the engine and
check that the
airbag indicator light goes out. If the in-
dicator light stays on, the
airbag system will not func-
tion as designed. Have the system diagnosed and
repaired by an authorized
BMW dealer.
- Installation is reverse of removal.
MFL steering wheel: Torque airbag using specification list-
ed below.
- Sport steering wheel: Press airbag unit mounting pins into
