When Monitored
WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
Whenever a valid FOBIK is in the vehicle and the ignition is turned to the ON position or a valid remote start is active, the RF Hub/PCM handshake takes place. The RF Hub validates that the message is sent to, and received by the PCM.
