Continental AG I BS PG3 CFRF WM Page 2 of 7 1. GENERAL DESCRIPTION OF THE RF TRANSMITTER The Acura fob is a transmitter designed to provide remote keyless entry, passive entry, passive engine start, and immobilization functionality. The term that Honda uses to describe such a transmitter is a SMART fob. The Acura fob MY18 is initially going to launch in North America on the platform RDX. There are supported different button-variants: 4 Button 3 Button Within the housing is applied an inner container, containing a lower container and container cover which are laser welded. Within the container is placed a PCB, which is the same type for all variants and containing a different number of switches. The fobs are part of a larger system provided to Honda by Continental which allows the customer to: • Remotely lock the doors. • Remotely unlock the doors. • Remotely open the trunk. • Remotely activate the alarm (panic mode). • Remotely unlock and lock doors in passive mode (PASE). • Start engine in passive mode (PASE). • Start the car via fob slot (immobilization). • Use mechanical emergency key as back-up.
