Detailed Description

The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.

In the prior art, due to the highly integrated characteristic of the wire harness, the wire harness needs to be searched and measured one by one in a plurality of loops of the whole vehicle. Because the wiring harness is generally assembled on the vehicle body, a large number of parts need to be disassembled for examination. For the accidental complex problem, when the problem of the wiring harness cannot be determined, the parts are replaced blindly, so that the maintenance cost is greatly increased. The wiring solutions of the prior art therefore do not satisfy the need for a fast troubleshooting.

According to the ESP control unit circuit principle (as in fig. 1), ESP screening dedicated harnesses (as in fig. 2) are designed individually. The plug connector and the terminal in the special line are subjected to conduction test. In order to facilitate assembly and disassembly, the special wiring harness for troubleshooting independently exists and is not integrated with the original wiring harness. In order to facilitate finding the problem occurrence part, the sectional type is still adopted, the plug connectors with the same butt joint type of the original vehicle can be adopted, the arrangement form of the original vehicle is restored, and the mutual connection of the special line and the original vehicle line is realized. Signals such as power supply, grounding and the like required in the troubleshooting special line are taken from the original vehicle, and electrical equipment does not need to be additionally arranged. Can be flexibly applied according to the complexity of the problem. The invention further improves the problem troubleshooting efficiency and accuracy and reduces the problem troubleshooting difficulty and workload.

As shown in fig. 1, which is a connection diagram of the prior art, an ESP switch, an EPB switch, a wheel speed sensor, etc. are connected to an ESP module (integrated EPB) through a vehicle integrated harness, which is inconvenient for troubleshooting of harness faults, and therefore, needs to be improved.
