Abstract

The invention discloses a diagnosis system and a diagnosis method for passenger vehicles. The diagnosis system for passenger vehicles comprises a vehicle-mounted communication module, a vehicle standard OBDII diagnosis module, a wireless communication module and client terminal software. The diagnosis method comprises the steps of connecting the vehicle-mounted communication module with the vehicle standard OBDII diagnosis module to receive the state information of a vehicle; and transmitting the received information to an intelligent mobile phone, a personal computer or a tablet computer provided with the client terminal software by means of the wireless communication module. The intelligent mobile phone, the personal computer and the tablet computer are connected with a manufacturer's service center. Thus, a client can know the information such as vehicle state, fuel economy, loss, emission, faults and the like through the terminal software. The terminal software can analyze the data, evaluate whether the vehicle is needed to be maintained and whether a driver has good driving habits, and display information such as monthly or annual carbon discharge and the like for a user. The terminal software also can provide professional diagnosis service. If the client does not understand professional information, the client can send the data to the manufacturer service center so as to obtain high-efficiency diagnosis and service.
