PURPOSE:To omit an alteration switch, a resistor and a buffer circuit and to simplify the constitution and operation by discriminating whether a value taken out from a diagnosis program is a specific value or not and executing the program in accordance with the discriminated result. CONSTITUTION:At the start of a moment limiter, the value of a specific address of an ROM 12a in which the diagnosis program is stored, i.e. a specific value, is taken out at first independently of the fitting of a diagnosis cassette 40 to a connector 29, whether the fetched value is the specific value or not is discriminated and then the program is executed in accordance with the discriminated result. Consequently, the alteration switch for a control program and the diagnosis program, the resistor, the buffer circuit, etc. can be omitted and the constitution and operation can be simplified. |
