Abstract: As an important carrier of automotive electrical system, wire harness plays an important role in the realization of various electrical functions. This paper briefly describes the composition of automotive electrical wiring harness, and focuses on five commom wiring harness failure modes in vehicle assembly. Combined with work experience for each failure mode’s generation mechanism and control measures to do in-depth analysis, for the automotive wiring harness processing, assembly and fault repair has a strong reference significance. The improvement of vehicle wiring harness quality is a systematic engineering, which needs to control the quality of wiring harness design, processing, distribution and assembly, and ultimately improve the quality stability of vehicle electrical appliances.
