Introduction




Central Locking and Soft Close Automatic Doors

The Central Locking system (ZV) of the E65/E66 controls the:

- Door locks (optional soft-close).
- Trunk lid lock and soft close.
- Fuel tank filler flap locking.

Various improvements have been made to the system, however the greatest change from the previous model is that while the CAS contains the Central Locking Master functions, the output operations are de-centralized and carried out by several different modules.

The Central Locking may be operated from the following locations:

- Lock cylinder, driver's door.
- Remote Control (FZV function of FBD).
- Central locking button (CLB).
- Passenger compartment trunk lid release button (TOEHKI),
- Trunk-lid button, inside of trunk lid (TOEHKK, only if equipped with HKL).
- Outside trunk-lid button (TOEHK).
- Hotel switch in lockable compartment in center console (hotel).

Unlocking via the crash sensor and forced double unlocking via the "key-inserted signal" in the Car Access System (CAS) and the central locking button are possible.

The following central-locking functions can be controlled by way of the operating locations:

- Locking
- Double locking
- Selective unlocking
- Unlocking
- Soft close (optional for the doors)

In order to improve anti-theft security, the lock cylinder in the trunk lid is now only used for mechanical emergency unlocking.

The individual components communicate with each other via the K-CAN P and wit1 the rest of the vehicle via the K-CAN S (e.g. anti-theft alarm system).

The FZV is connected by way of a separate unidirectional line to the CAS control unit.
