Abstract

The present invention provides an individual car diagnostic system and method based on a mobile intelligent terminal. The system includes a mobile intelligent terminal (1), a diagnostic connector (2) communicating with the mobile intelligent terminal, and a backstage server (3) communicating with the mobile intelligent terminal (1). The mobile intelligent terminal (1) has a wireless communication function, a network function, and a display function, and has a client software (13) and a car diagnostic application software (15). The mobile intelligent terminal (1) is connected to the diagnostic connector (2) via a wireless communication manner. The mobile intelligent terminal (1) communicates with the backstage server (3) via network function, to realize update and upgrade of the client software (13) and the car diagnostic application software (15). The diagnostic connector (2) is connected to a car diagnostic seat (5), to achieve communication between the diagnostic connector (2) and a car ECU (7).
