Set Condition:

WARNING: This page is about a different car, the 2012 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Radio Frequency Hub (RF Hub) receives and monitors the VIN messages from the Powertrain Control Module (PCM) and the Body Control Module (BCM). If the VIN is different from the last VIN it received, it will set this code. If the module was used on a previous vehicle, the VIN will be set to that vehicle.
