ABSTRACT:
An engine start controlling device prevents an engine from starting with exchanged ECUs. In a non-volatile memory 20f of an engine control ECU 20, information regarding whether or not an immobilizer function is used is stored, while a judging unit 20e interprets signals from input terminals 40-1-40-n and judges whether or not an immobilizer function is available. Only when the signals from the input terminals 40-1-40-n show immobilizer function unavailableness does the ECU operate as an ECU without the immobilizer function.
