Methods that can be detected in the event of an automotive wiring harness malfunction

The automobile wiring harness is the main body of the automobile circuit network. Without the automobile wiring harness, there will be no automobile circuit. The wiring harness is a component that connects the power supply circuit by binding the external plastic insulator or additional metal material shell after the contact terminal (connector) made of copper material is pressed on the wire and cable. Automobile harness fault can be detected by the following methods: 1. Automobile harness special tool test method test lamp detection method is more suitable for checking the general fault state of open circuit of transmission line. When using the temporary test lamp method, the output power of the test lamp should not be too large. When testing whether there is output or whether there is sufficient output at the operating output terminal of the electronic instrument panel, special care should be taken to avoid damage to the instrument panel caused by overload. It is best to use a diode test light. 2. Visual test method of automobile wiring harness When a common fault occurs in a part of the automobile electrical system, there will be smoke, flame, sound, burning smell, high temperature and other abnormal conditions. Through the visual inspection of listening, touching, odor, automobile wiring harness and household appliances of body sensory organs, the location of common faults can be distinguished, which greatly speeds up the maintenance speed. For example, when common faults occur in automobile routes, abnormal phenomena such as smoke, flame, sound, burning smell of plastic, high temperature and so on often occur. According to the visual inspection, the location of the fault and the general fault characteristics can be quickly distinguished. Automobile wiring harness instrument equipment test method can diagnose automobile circuit fault by using integrated fault detector, digital multimeter, oscilloscope, current clamp and other instrument equipment. For the vehicle with electronic control system, the integrated fault diagnosis instrument is generally used to search the fault code and determine the fault range of the vehicle. Then, check the operating voltage, resistance, current or waveform of the relevant power supply circuit with a digital multimeter, current clamp or pipa to determine the fault location of the automotive wiring harness transmission line.
