在车辆上检测线前进行一次二级维护,有利于恢复车辆各总成的技术性能及整车状况。但事实上不管是大修或是二级维护,刚竣工出厂的车辆仍有相当部分无法通过检测线的检测,一次检测合格率低,究其原因,主要是缺少针对性的检验。因为无论是汽车安全性能检测线还是综合性能检测线,其检测内容并非二级维护作业内容所能包容,如果仅以二级维护要求检验车辆,难免有疏忽遗漏之处,特别是一些 Conducting a second-level maintenance before the test line on the vehicle is conducive to restoring the technical performance and vehicle condition of the vehicle assembly. But in fact whether it is overhaul or secondary maintenance, just completed the factory vehicles still have a considerable part of the test line can not pass the test, a test pass rate is low, the reason is mainly lack of targeted testing. Because both the vehicle safety testing line or the comprehensive performance testing line, the test content is not secondary maintenance work content can be tolerated, if only two levels of maintenance requirements of vehicles, it is inevitable omissions, especially some
