Embodiment Construction

[0022] The present invention is further described below in conjunction with accompanying drawing:

[0023] like Figure 1-5 As shown, a method for troubleshooting an automobile electrical system is carried out on an established vehicle impedance database. The vehicle impedance database consists of five levels. The first level is the impedance value of the entire vehicle electrical system under normal conditions. The impedance value of the vehicle electrical system is Figure 5 The electrical system impedance of the vehicle is 4, and the second level is the electrical system impedance value of the vehicle under normal conditions. The electrical system impedance value is Figure 4 The impedance of the electrical system in 3, the third level is the impedance value of the electrical device under normal conditions of the vehicle, and the impedance value of the electrical device is image 3 The impedance of electrical components in 2, the fourth level is the loop impedance value o...

Abstract

The invention relates to an automobile electrical system troubleshooting method which is carried out on an established vehicle impedance database, the vehicle impedance database is composed of five levels, the first level is a vehicle electrical system impedance value, the second level is an electrical system impedance value, the third level is an electrical device impedance value, the fourth level is a loop impedance value, and the fifth level is an impedance value under various fault modes; when hidden faults of the whole vehicle are checked, step-by-step checking is started from the first level, checking is carried out in four steps, and when it is determined that a specific electric appliance system breaks down, checking is started in the third step; when it is determined that a specific electric device breaks down, troubleshooting is started from the fourth step; the troubleshooting method is simple in step, troubleshooting is efficient and accurate, the fault problem can be solved at a time, and parts do not need to be repeatedly unloaded during troubleshooting.

Description

technical field [0001] The invention relates to a method for troubleshooting an automobile, in particular to a method for troubleshooting an automobile electrical system. Background technique [0002] The investigation of electrical faults of the whole vehicle is a very headache for after-sales problems. The existing investigation methods and steps are as follows: first determine the fault symptoms, and then use a diagnostic instrument to diagnose the corresponding system according to the fault symptoms, and then check through the diagnostic information Circuit-related parts, and the final replacement of abnormal circuit parts will generally be locked in electrical devices or electrical systems. Existing troubleshooting methods are only aimed at fault phenomena, and cannot detect potential safety hazards hidden in the circuit. In this way, it is difficult to completely solve the fault problem even if the electrical components are replaced, resulting in repeated replacement o...
