Abstract

An engine starting apparatus with an antitheft function enables rapid and secure starting of a kick-started engine. The engine starting apparatus includes an immobilizer CPU and an ignition CPU, which cooperate to enable authorized engine startup and to prevent unauthorized access. The immobilizer CPU outputs a permission signal if an authentication code from the outside corresponds to a reference code in a vehicle, but outputs an inhibition signal if the authentication code and the reference code fail to correspond. When a starting pedal is kicked, the ignition CPU begins to energize the engine's ignition system, in response to a predetermined engine starting instruction, before the input reference code is verified. If proper authentication is verified by the permission signal, the ignition CPU continues to allow normal engine starting procedure. If the inhibition signal is received from the immobilizer CPU, the ignition CPU interrupts the normal procedure and inhibits engine starting.
