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.
