SYSTEM AND METHOD FOR DIAGNOSING AN AUTOMOTIVE VEHICLE

摘要

A system for diagnosing an automotive vehicle comprising sensing means for generating a sensing signal representative of a physical quantity of the automotive vehicle and a diagnostic testing device comprising a sensing input for receiving the sensing signal from a dedicated sensor device for cooperation with the testing device. The sensing means comprise a communication unit, operationally connectable to a diagnostic data communication port of the vehicle for communicating diagnostic data with the automotive vehicle via a diagnostic data communication link and a sensing signal generation unit for converting a part of the diagnostic data into a signal compatible with the sensing input of the diagnostic testing device in this manner, and existing diagnostic testing device, such as a vehicle exhaust emissions tester can be used with any type of vehicle equipped with a diagnostic data communication port, while avoiding a need to establish operational connections between one or more sensing devices and the vehicle.
