<p>PURPOSE:To improve the operability for setting and resetting in an automobile antitheft device. CONSTITUTION:When an antitheft switch 26 is connected. and a theft detecting part 30 is in the set mode, the display signal is outputted from a processing part to a light emitting diode 32, and a setting circuit 33 is in the set mode in response thereto, and the set mode signal is outputted to a latch circuit 34. The latch circuit 34 disconnects a relay 36 interposed in a power source line 44 connecting a fuel pump 31 to a control device 40 in response thereto, and nullifies the starting of the internal combustion engine and prevents the theft. A key cylinder switch 39 is connected by inserting a key into an ignition key cylinder, and in response to the connection of the ignition switch 37, the reset signal is outputted from the reset circuit 35 to the latch circuit 34. The latch circuit 34 releases the disconnection of the relay 36 in response thereto.</p> |
