Abstract
An electronic control unit performs self-diagnosis based on signals received from various sensors, and stores abnormality data in an EEPROM when abnormality is detected. The DTC is stored in a first memory area and a second memory area of the EEPROM, if a condition flag stored in the EEPROM is OFF and ON, respectively. The condition flag is switched from OFF (initial value) to ON, when service start data is received from a telematics service center in a period from the completion of assembling the electronic control unit to the vehicle to the start of use of the vehicle by a user.
