1. A vehicle diagnosing apparatus for communicating with an electronic control unit mounted on a vehicle from outside the vehicle and determining whether or not the vehicle has passed with respect to a plurality of diagnostic items based on various data transmitted from the electronic control unit, the vehicle diagnosing apparatus comprising:
- a first diagnostic unit for executing a first diagnostic program;
a second diagnostic unit for executing a second diagnostic program which is different from the first diagnostic program; and
a communication unit for communicating with the electronic control unit;
wherein after the communication unit has received a request for requesting the electronic control unit to send first data, from the first diagnostic unit, when the communication unit has received a request for requesting the electronic control unit to send second data, from the first diagnostic unit,if the first data and the second data are of the same type, then the communication unit requests the electronic control unit to send the same type of data, and sends the same type of data received from the electronic control unit, to the first diagnostic unit and the second diagnostic unit, andif the first data and the second data are of different types, then the communication unit requests the electronic control unit to send the first data and the second data, receives the first data and the second data all together from the electronic control unit, sends the received first data to the first diagnostic unit, and sends the received second data to the second diagnostic unit.
