Functions Of The Central Locking System

Unlike previous systems, a two-motor lock is used here.

The locked motor switches the central locking system from unlocked to locked and vice versa.

The safe motor switches the central locking system from locked to safe and vice versa.

The central locking system has three different locking states:

Action 1 - If the lock is actuated once, the so-called Safe locking - door secured function is activated. The doors can be opened only with the key, but not with the inner door handles.
Action 2 - If the door lock is actuated twice within 1 second, the vehicle is not accessible from the outside, but can be unlocked using the inner door handles.
Emergency locking. This locking state is activated by actuating the door lock three times and represents an emergency function. If the functional capability of the overall system is impaired because, for example, one door cannot be closed, it is still possible to activate the other security functions in this way. Point 1 is activated when the system is operated via the hand-held transmitter. The position of the doors is checked by limit switches in the lock.

The conditions for completing a locking process from unlocked to locked are listed in the following table.

Unlocked -> Locked

CONDITIONS FOR COMPLETING A LOCKING PROCESS FROM UNLOCKED TO LOCKED

Triggering condition	Requirements
Door lock barrel: Central locking system - Action 2	Driver's door closed Pin 86 S off Pin 15 off No valid transponder (no ignition key inserted)
Radio transmitter: Central locking system - Action 2	Driver's door closed Pin 86 S off Pin 15 off No valid transponder (no ignition key inserted)
Door lock barrel: Emergency locking	Possible at any time
Central locking switch: Actuated to Closed	Driver's and passenger's door closed Pins 86 S and 15 were deactivated for at least 2 seconds after crash unlocking
Speed > V_gr (version coding)	Driver's and passenger's door closed Pin 15 Pin 86 S Pins 86 S and 15 were deactivated for at least 2 seconds after crash unlocking
Pin 15 on (version coding)	Driver's and passenger's door closed Pins 86 S and 15 were deactivated for at least 2 seconds after crash unlocking

The conditions for completing a locking process from safe to locked are listed in the following table.

Safe -> Locked

CONDITIONS FOR COMPLETING A LOCKING PROCESS FROM SAFE TO LOCKED

Triggering condition	Requirements
Central locking system was unlocked, door lock barrel or radio transmitter are actuated twice in 1 second, the central locking system lock is already in safe position after the first actuation and before the second actuation is detected.	As for Unlocked -> Safe
Central locking system already in safe position and door lock barrel is actuated to closed twice in 1 second.	As for Unlocked -> Safe
Safe position of a door is detected during pin 15.	Pin 15 At least one door is in safe position Alarm system not activated
Pin 86 S on	Within 10 seconds or in the inactive period after the locking command is given once
Pin 15 on or valid transponder
A valid transponder is detected
IR sensor detects movement	System is in the time window for movement detection

Locked -> Unlocked

CONDITIONS FOR COMPLETING A LOCKING PROCESS FROM LOCKED TO UNLOCKED

Triggering condition	Requirements
Door lock barrel: Actuated to open	Not for coding variant deactivate only via radio, if alarm system is activated
Radio transmitter: Actuated once	Pin 86 S off (at least 2 seconds)
Central locking switch: Actuated to open	Both doors closed and Doors are locked both with central locking switch or After locking with pin 15 or After locking via speed signal
Unlocking a door via inner actuating mechanism	Locking performed either with central locking switch or After a valid transponder is detected or After locking with pin 15 on or After locking via speed signal
Crash signal	Pin 86 S or Pin 15
Desired locked position is not achieved	Not applicable for emergency function or for actuating central locking switch.
