Theory of Operation

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. 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 Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on the programmed status of the FOBIK.
