Abstract: The disclosed device is an additional, normally-closed relay positioned in line with the ignition switch and the functionality controlled by the OEM, normally-open relay. When the aftermarket system is in the disarmed state, the normally-closed relay is dormant in its closed position, thereby allowing the circuit to complete its intended loop. When the aftermarket security system is enabled, the normally-closed relay will open the current flow and prevent the current from reaching its target, thereby disrupting or disabling the operation of the vehicle function. If the normally-closed relay fails, it fails in its closed position, thereby not affecting the OEM system.

Abstract: A request signal transmitted from LF antennas of a vehicle-mounted unit is received by a radio terminal through an LF antenna. In response to the request signal, the radio terminal transmits a response signal from an antenna. The response signal is received by an RF unit of the vehicle-mounted unit.

The radio terminal has a light-emitting diode. When the radio terminal receives a failure diagnosis signal that is transmitted instead of the request signal, the radio terminal does not transmit a response signal, but energizes the light-emitting diode.
