The invention discloses a vehicle diagnosis method. The method comprises the steps that a vehicle-mounted diagnostic device (24) arranged on a vehicle (20) starts one or more of electronic control units (26) arranged on the vehicle (20) after a diagnosis request command is received; the one or more of electronic control units (26) diagnose the vehicle (20) so as to obtain the diagnosis data of the vehicle (20); the vehicle-mounted diagnostic device (24) reads the diagnosis data of the one or more of electronic control units (26) and transmits to a vehicle diagnosis application program (100) arranged on a hand-held electronic device (10); and the vehicle diagnosis application program (100) receives the diagnosis data transmitted by the vehicle-mounted diagnostic device (24) and processes the diagnosis data so as to judge whether the vehicle (20) is broken down. The invention further provides a vehicle diagnosis system. According to the vehicle diagnosis method, the hand-held electronic device is utilized to diagnose the vehicle, so that a serviceman can conveniently maintain the vehicle and the diagnosis efficiency can be improved.
Description
technical field [0001] The invention relates to an automobile diagnosis system and method, in particular to a system and method for diagnosing automobiles through a hand-held electronic device. Background technique [0002] Automobile fault diagnosis instrument is an essential equipment for automobile maintenance manufacturers and a good helper for automobile maintenance masters. Modern automobile technology is developing rapidly, and experience alone cannot solve the problems encountered in the current repair process. By connecting with the car, the car fault diagnosis instrument can accurately understand all the static and dynamic conditions of the car, as well as the fault code, data flow, and the working status of each component. The car fault diagnosis instrument can quickly and accurately understand the condition of the car, which brings great convenience to the maintenance of the car. [0003] However, most of the current automotive fault diagnosis instruments are b...
