Vehicle Theft Alarm: Enabling
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.
The Body Control Module (BCM) (also known as the Common Body Controller/CBC) must have the Vehicle Theft Alarm (VTA) function electronically enabled in order for the VTA to perform as designed. The logic within the BCM keeps its VTA function dormant until it is enabled using a diagnostic scan tool. The VTA function of the BCM is enabled on vehicles equipped with the VTA option at the factory, but a service replacement BCM must be VTA-enabled by the dealer using a diagnostic scan tool. Refer to the appropriate diagnostic information.
