WARNING: This page is about a different car, the 2012 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
When the driver starts the vehicle (through the push button switch), activates the front door handles or activates the liftgate switch, the PEM module fires the antennas and verifies the programed FOBIK. If it finds that the signal or return circuit of antenna 1 is open, short to ground, short to battery or the antenna terminals are shorted, it will set this code.
