FUNCTIONAL DESCRIPTION
1 System Components
The HMC TG System is a vehicle remote keyless entry (RKE) system. This system
consists of a Stand alone- type of receicer(SRx) with corresponding a RKE transmitter.
SRx has implemented on board with RF generic receiver device
The described system is a radio-frequency remote control for central doors locking /
unlocking, trunk release and Panic activity of an automotive vehicle. This system will be a
part of the equipment of the HMC TG vehicles.
The system is composed of the following ones:
transmitter with 4 buttons (doors locking, door unlocking, and trunk release)
System Operation:
To serve a remote keyless entry system for the HMC TG RKE system. Remote keyless
entry function is provided by the RF system of the SRx and the RKE transmitter. The
operation of these functions are as follows:
Identifier
RF Key
Start code

Remote keyless Entry:
The RKE transmitter transmits at 433.92 MHz for ECE ( or 315MHz for NA) an FSK
modulated data signal to the SRx. The RF system of SRx receives this encrypted RF
signal. The SRx send the signal to corresponding the host Body control module through
single wired K-line bus then the host module broadcasts the requested remote commands
to the appropriate control modules in the vehicle through CAN –communication line . In
general the following functions are provided:
Lock the car
Unlock the car
Unlock the trunk of the car
Panic
