Electronic control system diagnostic box

Abstract

The invention provides an electronic control system diagnostic box. The electronic control system diagnostic box includes a diagnostic box body and the test switch cord. Installed on the diagnostic box body is a voltage detection device, a voltage display device, at least one test input port and a plurality of transit ports, the test input port includes a plurality of test pins; a plurality of transit ports are placed on the diagnostic box body, through the transmission line connects one-to-one correspondingly with a plurality of test pins; the voltage detection device is used to connect the transit port, in order to detect the voltage value of the transit port access; the voltage display device is used to display the detected voltage value by the voltage detection device; the first port of the test switch cord connects with the test input port, the second port of the test switch cord connects with the output port of the tested circuit. Through the deployment of the present invention, the trouble shooting process of the electronic control system can be simplified, which effectively reduces the misjudgments of the inspection staff and increases work load efficiency.

Description

technical field [0001] The invention relates to fault diagnosis technology, in particular to a diagnostic box for an electric control system. Background technique [0002] When troubleshooting vehicle faults, due to the many circuits of the electronic control system, the different arrangement of needles and threads, and the dense arrangement of pins, there are many inconveniences for the inspectors when performing measurements, and the safety is poor. Moreover, misjudgment of the fault point is more likely to occur, and once a misjudgment occurs, unnecessary losses will be caused. [0003] Therefore, in order to improve labor efficiency, simplify the troubleshooting process of the electronic control system, and avoid damage to the special-shaped plug-ins and pins of each electronic control system due to improper operation, it is necessary to develop a diagnostic method to deal with the above situations. Contents of the invention [0004] The main purpose of the embodiment...
