Passive Entry Of Antenna 3 - Circuit Short To Battery
Passive Entry Of Antenna 3 - Circuit Short To Battery
Description
The Passive Entry (PE) antenna units allow the transmitter within the Radio Frequency Hub (also known as the RF Hub) to communicate via Low Frequency (LF) radio transmission with a Frequency Operated Button with Integrated Key (FOBIK) that is located inside the vehicle or, at most, about 2 meters (6.5 feet) horizontally in all directions around the outside of the vehicle. The RF Hub uses communication through the antenna units to wake up and challenge a FOBIK that is within range in order to authenticate whether that FOBIK is valid (programmed) to the vehicle. The RF Hub communicates with the FOBIK using Frequency-Shift Keying (FSK) modulation.
