Abstract:
1. An external diagnosing apparatus for performing data communications with an electronic control unit, hereinafter referred to as an ECU, mounted on a vehicle from outside of the vehicle, acquiring sensor detected values of the vehicle through the ECU, and diagnosing the vehicle, comprising: an external-diagnosing-apparatus-side electric power line connected to a vehicle-side electric power line, the vehicle-side electric power line configured to supply electric power from a vehicle-mounted power supply to the external diagnosing apparatus when an ignition switch of the vehicle is on, and configured to stop supply of electric power from the vehicle-mounted power supply when the ignition switch is off; a capacitor being connected to the external-diagnosing-apparatus-side electric power line and storing electric power, the capacitor being charged with the electric power from the vehicle-mounted power supply when the ignition switch is on, and supplying the charged electric power to the external diagnosing apparatus after the ignition switch has been turned off; a requested job input unit having input thereto a requested job for the external diagnosing apparatus; a memory-related job judging section configured to judge whether or not the requested job input to the requested job input unit is a memory-related job that needs to activate a memory check program of the ECU; and a time limit display unit configured to display an operation interval time limit after the ignition switch has been turned off and until the ignition switch is subsequently turned on again in order to restart the ECU, in a case that the memory-related job judging section judges that the requested job is the memory-related job and in a case that the requested job is finished.
