Abstract

The invention relates to the technical field of automobile fault diagnosis, in particular to a vehicle fault one-key diagnosis system which comprises a software system and a reading device, and the software system comprises a fault code diagnosis module, a data flow analyzing module, a first communication module and an operation platform. The reading device comprises a connecting port, a transmission module and a communication module II; the connecting port is used for being connected with a vehicle-mounted diagnostic system of a vehicle, and the transmission module communicates with the vehicle-mounted diagnostic system to obtain diagnostic data in the vehicle-mounted diagnostic system; and vehicle condition information is read between the reading devices, the data is quickly and accurately analyzed through the software system, the fault analyzing result is displayed on the operation platform, and the vehicle condition diagnosis system has the advantages of being convenient to use and capable of quickly diagnosing the vehicle condition without practical experience.

Description

technical field [0001] The invention belongs to the technical field of automobile fault diagnosis, and specifically relates to a one-key diagnosis system for vehicle faults. Background technique [0002] As early as the 1980s when automobiles entered the period of computer control, major automobile manufacturers in the United States, Japan, and Europe began to equip OBD (on-board automatic diagnostic system), and the development of OBD system experienced OBDⅠ, OBDⅡ and OBDⅢ. In the mid-1990s, SAE in the United States formulated the OBD II with a unified diagnostic mode, which made OBD have a unified standard, which brought a lot of convenience to the fault diagnosis and inspection and maintenance of automobiles. In the OBD II system, the signal of the automotive electronic control system is abnormal and exceeds the normal range of change, and the ECU judges it as a fault, and the monitor stores this fault in the form of standard codes in the fault memory inside the ECU. Wit...
