A vehicle security system, for a vehicle of a type including a data communications bus, preferably includes at least one security function control circuit and associated interface for interfacing to the data communications bus. The system also includes a security system controller and associated interface for interfacing to the data communications bus, and a desired signal enabling circuit for enabling the security system controller to operate using a desired set of signals for a corresponding desired vehicle from a plurality of sets of signals for different vehicles. This, in turn, permits the security system controller to communicate with the at least one security function control circuit. The at least one vehicle function control circuit may be an engine control circuit, such as a starter control circuit, or at least one of an ignition and fuel control circuit. The vehicle function control circuit may also be a door lock control circuit. |
