5 Series E60 525d (M57TU) SAL
Brief description of components
The following components supply an input signal for the central locking system:
-
Driver's door lock cylinder
The driver's door lock cylinder allows manual locking/deadlocking and unlocking of the vehicle. If the vehicle's
electrical system fails, the driver's door can be unlocked manually using the ignition key.
-
Interior boot lid pushbutton in the driver's footwell
The interior boot lid pushbutton allows the boot lid to be opened while the vehicle is stationary (terminal R OFF).
-
Central locking button
The central locking button allows the vehicle to be locked/unlocked from the passenger compartment. The fuel
filler flap is not locked.
-
Remote control
The remote control allows the vehicle to be locked/deadlocked via radio (aerial interface). The radio signals from
the remote control are received by the FBD receiver (receiver for remote control) and transferred to the CAS
control unit.
-
Lock cylinder on the boot lid
The boot lid lock cylinder allows the boot lid to be opened manually (E60, E63, E64 only).
On the E60 the hotel position is also applied via the lock cylinder.
On the E63/E64 the hotel position is applied in the rear stowage compartment in the centre console (hotel
position switch). This means that, in addition to the boot lid, the front stowage compartment can also be
uncoupled from the central locking system.
-
External boot lid pushbutton
The external boot lid pushbutton allows the boot lid to be opened while the vehicle is unlocked and stationary
(hotel position not applied).
Via the BMW badge on the E63/E64.
-
Rear window switch (E61 only)
The rear window switch allows the rear window to be opened while the vehicle is unlocked and stationary (hotel
position not applied). The rear window switch is integrated in the rear window wiper.
-
Door contacts
The signals from the door contacts are analysed by different systems.
For example, the anti-theft alarm DWA requires the signals to monitor the doors.
The following control units are involved in the central locking system:
-
CAS: Car Access System
All the rules for controlling the central locking are integrated in the Car Access System. The commands are
transferred by the CAS control unit via the K-CAN.
