Functional description RFA
The RFA is a module installed to receive the messages transmitted by RF keys or TPMS
valves using 433Mhz or 315Mhz depending on market. It is placed behind the instrument
panel cluster.
With every button push, the 32-bit transmitter ID, a synchronization counter and the
requested command is transmitted in an encrypted sequence.
There are several features which may be initiated by RF key, all explained below.

Lock / Unlock
The Remote Control Access feature enables the customer to lock, unlock, and theft-security
lock their vehicle as well as request initiation or termination of motion of power closures such
as liftgates.
The operator is able to initiate unlocking of one or more vehicle doors with one or more
presses of the remote transmitter Unlock button. Based on personalization settings, either
the driver door or all doors will unlock upon the first press of the remote unlock button. The
second press of the remote unlock button within a calibratable time period (default of 5
seconds) will always result in unlocking of all doors.
The operator is able to initiate locking of vehicle doors or theft-security locking of all vehicle
doors with one or more presses of the remote transmitter Lock button.

Comfort Open / Comfort Close
The Remote Comfort Open & Remote Comfort Close features allow the customer the
convenience of opening or closing all of the vehicle's powered windows simultaneously
based on a remote transmitter button press.
Comfort Open: A press & hold of the remote transmitter's Unlock button while in range of
the vehicle, when the comfort open calibration is enabled, shall cause the vehicle's powered
windows to travel toward their full open positions, for as long as the button remains pressed
or until the full open positions are reached.
Comfort Close: same functionality as “Comfort Open”; the driver must use the transmitter’s
Lock button.

Vehicle Locate
The Remote Vehicle Locate feature enables the customer to activate the vehicle's horn,
when enabled, and exterior lights by pressing the remote transmitter alarm button in range
of their vehicle. The vehicle locate feature is intended to serve as an audible and visual aid
in locating the vehicle.

and hold of the remote transmitter Liftgate button.
The operator is able to request that motion of a vehicle’s power liftgate stop with the press
of the remote transmitter Liftgate button while the liftgate is in motion.
