The central locking system controls the function "Remote controlled opening and closing" of the vehicle. These convenience features are constituents of the drive authorization system (DAS [FBS] 3).
The EIS [EZS] control unit (N73) has a central function here.
The following functions are performed:
- Managing right/left-hand steering functions and corresponding assignment of front door control units for driver and passenger door
- Managing outer safety statuses and corresponding transmission of closing messages for individual doors, the rear-end door and fuel filler flap according to global/selective preselection.
- Enable and disable of unlocking functions for CL inside switch
- Control of automatic door locking via v-signal, (greater than v = 15 km/h)
- Administers the automatic locking function.
- Control of relocking when a door/trunk lid is not opened within 40 s after CL is opened.
- Control of relocking with door open/closed and exceeding v- threshold again.
- Transmits messages for external securing and external enabling.
- Switching off remote control functions, when key is inserted
- Definition of memory range for determination of selective opening via diagnosis
- Re-enables locking functions after emergency opening (crash).
- Monitors the actuation frequency of the CL (play protection).
The central locking can be operated in various manners:
- By remote control with transmitter key.
- Operation with the interior switch.
- By opening the driver door from the inside
