Central locking (CL), function - GF80.20-P-0005T

MODEL 211.0/2 

The central locking (CL) actuates 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 module (N73) has a central function here. This performs the following functions:

• Manages right/left-hand drive vehicle functions and corresponding assignment to front door control modules for driver and passenger door
• Manages outer safety statuses and corresponding transmission of locking messages for doors, trunk lid and fuel filler flap according to global/selective preselection.
• Enables and disables CL inner actuation and remote trunk lid release
• Controls automatic locking door feature at speeds over 15 km/h.
• Manages "Automatic locking" function
• Controls relocking when a door or trunk lid is not opened within 40 s after "Open with CL"
• Re-enables locking functions after emergency opening (crash).
• Monitors actuation frequency of CL (play protection).
• Controls relocking door closed/open and exceeding speed threshold again.
• Transmits messages for external securing and external enabling.
• Switches off remote control functions when the transmitter key (A8/1) is inserted

The operations apply analogously also for vehicles with code (889) Keyless go.

The central locking system can be operated in various manners:

• With transmitter key (A8/1)
• Operation with interior central locking switch and ATA function display (N72/1s6)
• By opening a vehicle door from inside
