ECU BMW 540I 1997 E39 Central Body Electronics ZKE Manual

• The luggage compartment can be manually
locked with a “Master Key” and leaving the
lock cylinder in the horizontal position which
prevents opening by any other method (sec-
ured for valet).
The luggage compartment release button in-
side the vehicle will also be ignored by the GM.
Prior to 2000 MY the vehicle could be locked/
unlocked using the luggage compartment lock
cylinder.
• The glove box has a lock cylinder to secure the
contents by manual locking with a “Master
Key” and leaving the lock cylinder in the hori-
zontal position which prevents opening by any
other method (secured for valet).
• The E38 has a lever behind the glove box han
dle which permits locking the glove box with-
out a key. Opening still requires a key.
The valet key is not mechanically capable of
entering either of these lock cylinders.
• The Fuel Filler Flap mechanical release is found
in the right side of the luggage compartment.
The “pull tether” is behind the button as shown
on the right.
Note: Continuous operation of locking/unlocking will cause a timed arrest of the
locking system. When activated, the timed arrest lasts for 2 minutes (or recycle
the ignition KL15). The “crash” signal will override the timed arrest and unlock the
vehicle.
