Abstract
A wireless communication unit is built in a portable type diagnosing apparatus and an external computer respectively. The portable type diagnosing apparatus reads data from an electronic control unit of a vehicle and sends the data to the external computer by wireless. The external computer conducts miscellaneous calculations based on the data and displays the result of the calculations on a display of the external computer or analyzes failures of the vehicle in a running state. Further, when service manuals are needed, according to a command from the portable type diagnosing apparatus, they are sent from the external computer and displayed on a display of the portable type diagnosing apparatus.
