Siemens Automotive Systems Corp.ssive Start/Entry (PASE) system will soon be used by Cadillac as the first keyless system to be offered in North America. The Cadillac system differs from the comparable European Smart Card approach to passive entry/ignition in that it features a key fob that operates in two modes: an active remote keyless entry (RKE) mode that allows the driver to control vehicle locking, trunk release and remote engine start; or a totally passive mode that requires only that the driver carry the fob on their person as they approach and enter the vehicle.
Before the engine is permitted to start, the system verifies also that the fob is inside the vehicle and the brake pedal is fully depressed. Security functions include access control and deactivating the engine immobilization system and enabling the engine ignition.
