outline: 0px !important; font-size: 12pt;">故障检修:接到该车后，首先验证该车的故障现象，正如司机反应按下遥控器时，中控门锁</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">不</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">动作，且</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">无法着</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">车的同时还发现了该车的空调控制面板，导航收音机，车内室顶灯等都不能正常工作。并且在开钥匙时仪表中自检的时候仪表内的防盗指示灯不亮。故判定该车启动不着车是由于防盗未正常验证通过。本想着使用诊断仪进入该车的系统读取故障码的，结果发现诊断仪不能进入该车的任何系统。同时发现连接诊断仪时诊断仪上的插头指示灯不点亮，正常诊断仪的诊断插头在连接到车上的OBD接口时，诊断仪的插头上的指示灯会些亮，而该车却不点亮。然后根据OBD的针角定义，如下图所示:</span><br style="box-sizing: border-box;

outline: 0px !important; font-size: 12pt;">电瓶到OBD16号脚的线路开路。初步怀疑保险丝损坏。测量保险丝时，发现室内保险丝盒，烧断了室内灯的一枚保险丝。换上之后，此时OBD的16号脚电源正常，其他故障也恢复正常。反复试车后本以为故障解决，准备交车时，司机过来拿车时，又发现按下遥控器时，中控门锁</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">不</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">动作，启动不着车。打开室内保险丝盖，发现之前更换的保险丝烧断了，并且保险丝座也烧坏了，保险丝座后方的线束也烧化了。</span><span style="box-sizing: border-box;

font-size: 12pt;"> </span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;"><br style="box-sizing: border-box; outline: 0px !important;">心想有可能这一条线束在某处对地短路了，导致保险丝爆了，并且把线也烧了</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">。</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">为了验证心里的想法，重新更换一个</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">规定安数的</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">保险丝，结果还没插牢固，保险就爆了。确定此条保险丝后面的用电器，或者是线路，对地短路了。本想着通过电路图了解这一保险丝后的用电器，以及电器结构，却没有找到该车的电路图，没办法，只能从保险丝后面沿着线慢慢捋。因为之前在更换完保险丝后，所</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">有</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">的故障现象都好了</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">所以判断，这个保险丝后面的用电器一定会关联遥控接收器</span><span style="box-sizing: border-box; outline: 0px !important;

font-size: 12pt;">是先从电瓶出发，经过保险丝，通过导线到达该结点，然后再从该</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">节点</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">分给故障的用电器，其中就包括遥控接收器</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">防盗控制单元</span><span style="box-sizing: border-box;

font-size: 12pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">室内灯等等。为了便于维修，首先从保险丝</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">盒后面</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">顺着线</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">捋</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">然后顺着</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 12pt;">线</span><span style="box-sizing: border-box;
