Theory Of Operation
WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Ignition Node Module (IGNM), the Radio Frequency Hub (RF-Hub) performs a self test and resynchronization routine. During the routine, the RF-Hub interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on the programmed status of the FOBIK.
