Abstract
An emergency call terminal device is provided which may be employed in automotive vehicles to transmit, in the event of an emergency, data on the current location of the vehicle and registered information about the vehicle to an emergency center. The emergency call terminal device is designed to produce signals different in voltage level from each other depending upon operating states of an emergency call push button for discriminating between an open circuit-caused failure resulting from formation of an open circuit of an internal circuit of the device caused by an accidental disconnection of the internal circuit from the emergency call push button and a short circuit-caused failure resulting from formation of a short circuit of the internal circuit to ground caused by an accidental disconnection of the internal circuit from the emergency call push button.
