Description

technical field [0001] The invention relates to a device and a method for reading, recording and analyzing data of an automobile electronic control system. Background technique [0002] The automotive electronic control system (ECU) has a fault self-diagnosis function. When a fault signal is detected, it will be stored in the memory in the form of a fault code, and the fault code can be called out through a specific program to provide to the maintenance personnel. As a basis for judging the fault location and cause. With the increasingly complex automobile electronic control system, the automobile maintenance industry relies more and more on the automobile electronic control system detector; currently there are a large number of automobile fault diagnosis code reading devices on the market, including various types of automobile fault decoders And small car trouble code reading card. The traditional code-reading card is not inserted in the car diagnostic socket for a long t...
