Theory Of Operation

WARNING: This page is about a different car, the 2009 Jeep Grand Cherokee. 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) base station, 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 whether the FOBIK ID is received by the WIN.
