Central locking system
When the 3rd remote control button, "open tailgate", is operated, it is not only the tailgate that unlocks; all the doors on the vehicle are unlocked too.
This function change has been introduced to reduce the risk of accidentally locking the remote key in the luggage compartment.
For all vehicles in which the configurability via the headunit is not available:
With ISTA/P the assignment of the 3rd remote control button can be changed with a conversion.
Access control from the existing Car Access System (CAS) is fully integrated in the Front Electronic Module (FEM). Mechanical access to the vehicle is limited to opening of the driver's door lock. Activation of the central locking system is carried out via identification of the ID transmitter via the rear window aerial. The remote control receiver forwards the signal to the Front Electronic Module (FEM). After a successful signal check, the Front Electronic Module (FEM) initiates activation of the central locking system. The Front Electronic Module (FEM) evaluates the status of all door contacts. This prevents, for example, the vehicle from being locked if the driver's door is open. The Front Electronic Module (FEM) also evaluates the status of the central locking button. Depending on its status, the Front Electronic Module (FEM) activates the central locking system.
The Front Electronic Module (FEM) controls the coordinated unlocking, locking and deadlocking of the connected doors and flaps.
