Problems solved by technology

[0009] 1. Through the tooling test, only the continuity of the circuit can be ensured, and the functional differences caused by the differences in the components themselves cannot be detected;
[0010] 2. Judging the functionality of the diagnostic equipment through the vehicle communication module with a good diagnostic function. Each vehicle communication module has only one or two protocols. With the subjective judgment of testers, it is impossible to test in batches

Embodiment Construction

[0029] Such as figure 1 As shown, a detection method of vehicle diagnostic equipment, comprising:

[0030] 1. Test the initial channel to be tested of the second diagnostic device 120:

[0031] After the first diagnostic device 110 receives the first test command, it becomes the master device, and it sends the second test command to the second diagnostic device 120 through the preset test channel. After the second diagnostic device 120 receives the second test command, it enters the test mode, and become a slave device, and at the same time feed back the information that has entered the test mode to the first diagnostic device 110 through the preset initial channel to be tested. If the first diagnostic device 110 receives the feedback information from the second diagnostic device 120, it will judge the first The preset initial channel to be tested of the second diagnostic device 120 is normal, wherein the preset initial channel to be tested is of the same type as the preset t...

Abstract

A detection method for vehicle diagnostic equipment, comprising: testing an initial channel to be tested and testing each of the other groups of channels to be tested. The detection method of the present invention does not require other tooling equipment, low cost, the detection process can be quickly copied, all channels can be detected, master-slave equipment can be switched freely, there is no specific requirement, the detection is convenient and fast, the result is accurate and objective, and the detection can be completed in 10 seconds.

Description

technical field [0001] The invention relates to the technical field of vehicle diagnostic equipment, in particular to a detection method for vehicle diagnostic equipment. Background technique [0002] Diagnostic equipment is a device developed for vehicle diagnostics. It is used to communicate with the vehicle control module and read relevant parameters, which are used to optimize vehicle operation and after-sales maintenance. [0003] There are various communication methods of the vehicle control module, such as 232 protocol, 485 protocol, 1708 protocol, CAN protocol, K protocol and other protocols. In order to adapt to the various protocols of the car, the corresponding diagnostic equipment must have these functions. [0004] The more protocols supported by the diagnostic equipment, the more complex the design, and the higher the probability of failure. The original intention of the diagnostic equipment is to diagnose the vehicle. If the equipment itself has a fault, the...
