Abstract

The invention discloses a vehicle electric control system fault quick retrieval method. The vehicle electric control system fault quick retrieval method comprises the steps: obtaining a VIN (Vehicle Identification Number) for a vehicle through OBD (On Board Diagnostics); obtaining a manufacturer according to the first three digits of the VIN, and automatically starting a corresponding vehicle model diagnosis software; if the VIN is not obtained through OBD, selecting the corresponding vehicle information software, reading an engine electric control system, and supplementing the VIN information; and if the VIN information is not complete, quitting retrieval. The invention provides a vehicle electric control system fault quick retrieval method. The vehicle electric control system fault quick retrieval method has the advantages of being able to automatically acquire the VIN and automatically identify and diagnose the software, accurately positioning the electric control system of the whole vehicle, reducing the time for retrieving the fault of the electric control system, being more accurate in retrieval and diagnosis of the electric control system fault of the whole vehicle, and being clearer in retrieval and diagnosis of the electric control system fault of the whole vehicle.

Description

technical field [0001] The invention relates to a retrieval method, in particular to a rapid retrieval method for vehicle electric control system faults. Background technique [0002] At present, with the improvement of living standards and the rapid development of science and technology, automobiles have become common consumer goods for the masses. The automotive aftermarket is also in full swing, and maintenance is becoming more and more common. With the popularization of OBD and CANBUS communication protocols, the traditional vehicle fault retrieval is to select the vehicle information and then click on the corresponding electronic control system to obtain the fault information, which is time-consuming and incomplete, and the technician experience is not high. Contents of the invention [0003] The object of the present invention is to provide a method for quickly retrieving faults of the electronic control system of a vehicle in order to solve the above problems.
