color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; line-height: 1; font-size: 10.5pt; outline: 0px !important;">问题就出现在驾驶员侧车门控制单元20针脚插头12号脚到驾驶员车门限位器处28针脚插头的1号针脚线路断路或虚接。断开电源使用万用表二极管档测这根线的通断，蜂鸣器没有响，为了确定故障再使用万用表Ω档2K档位测线阻，显示为无穷大1（解释：测量线阻的时候一定要从大的档位开始测，因为小的档位测电阻过大也会显示为1）（如上图）。<p style="box-sizing: border-box;

margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; line-height: 1; font-size: 10.5pt; outline: 0px !important;">故障总结：由于长期开关门导致线路折断。我们有一个好的逻辑思维，其实修车不难，天下就没有疑难杂症，难的就是你不会的技术。
