es momentarily.
Release both buttons. GM immediately locks and unlocits
doors to signal successful initialization.
Remote system coding
* Initialize remaining lteys, repeating steps above.
The E39 remote entry system uses coded signals for security
purposes. The code signal sent by the transmitter is changed
every time the vehicle is lockedlunlocked with the transmitter.
A separate code signal is used for each transmitter that is ini-
tialized to the system. This allows for each transmitterto oper-
ate independently of the others.
Due to the changing of the code each time the buttons are de-
pressed, the system allows for a
lacit of synchronization be-
tween the transmitter and receiver. This would occur
if the
buttons on the transmitter are pressed inadvertently.
Up to
100 erroneous actuations of the transmitter are auto-
matically corrected
forby the control module. If more than 100
actuations are present, the operator need only to press the
button a second time to restore system operation.

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.
