2. Sounding a panic alarm during vehicle is not running. 
This system consists of RF Tuner, transmitters, and BCM. 
 
The RF Tuner (EUT) is supplied 5V from BCM. It is designed to operate on 
a single fixed frequency RF 433.92MHz by amplitude modulation. It receives 
unique identification code and function code transmitted from transmitters. 
After receiving RF signal, demodulation IC in Tuner demodulates RF signal 
from transmitters. And then driving circuit in Tuner outputs the 
demodulated signal to BCM.
