GF80.20-P-4009RT Automatic Locking, Function

Speed-dependent locking

Function requirements
^ Function in instrument cluster (A1) activated

Except the tank flap, the doors are locked at a speed of approx. 15 km/h and the trunk lid at a speed of approx. 3 km/h In this case, the EIS control unit (N73) transmits the "Locking" command to the controller area network bus class B (interior compartment) (CAN-B).
The door control units, the front SAM control unit (N10) and the rear SAM control unit (N10/8) then actuates the corresponding motor in the "Locking" direction.
The rear SAM control unit deactivates the rear-end door handle (S88/9).

The vehicle can be unlocked by opening the driver and passenger door from inside or by actuating the left interior CL switch (S85/5) or right interior CL switch (S85/6).
If, after locking, the vehicle is unlocked with the CL inner actuation switch, the vehicle also remains unlocked above the speed threshold.
If a door is opened and then closed again following automatic locking, when the vehicle speed is greater than the speed threshold, the door in question is locked again after it is closed.

The trunk lid is supported by an electric power locking unit.

Relock
The "Relock" function is actuated by the EIS control unit, if the vehicle is unlocked and none of the doors or the trunk lid are opened within 40 s Relock is confirmed by optical feedback

The status of the doors is evaluated by the rotary tumbler switches installed in the CL motor and the door control units, the front SAM control unit and the rear SAM control unit via CAN B.
