摘要： A first microcomputer (1) in an ECU (11) outputs a CID of the ECU (11) in response to a request from a scan tool (25) when the ECU (11) has multiple microcomputers (1, 2) implemented therein. Each of the multiple microcomputers (1, 2) has an additive value stored therein for counting an update of the software. The additive values from the multiple microcomputers (1, 2) are added as a sum total of the ECU (11) that is further added to a CID base value. The sum total of the ECU (11) added to the CID base value is then output as the CID of the ECU (11) from the first microcomputer (1) to the scan tool (25). Therefore, information stored in the first microcomputer (1) is not necessarily changed for outputting an updated CID (e.g., software product number information) from the ECU (11).

摘要： An electronic control unit (1) installed in a vehicle performs diagnosis of plural diagnosis objects based on sensor signals and the like, and stores diagnosis results that indicate abnormality of the diagnosis objects in a DTC storage area (11) only when the DTC storage area (11) does not store data having an initial value. The data in the DTC storage area (11) is, in other words, rewritten to different values from the initial value for allowing storage of DTC when the electronic control unit (1) determines that all of the diagnosis objects are in a normal condition with no indication of abnormality after performing diagnosis, thereby making it possible to exclusively preventing useless abnormality information detected during a vehicle manufacturing process from being stored in an rewritable non-volatile memory (11).
