font-size: 11pt;">：</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">通讯类故障出现的原因有</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">:</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">通讯模块的电源</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">接地</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">线路</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">网关，该条总线上的其他通讯模块内部的通讯芯片对地短路或者对正</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">极</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">短路</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">造成拉低或者拉高总线电压使整条总线瘫痪。在检修时第一步就测量了总线的电压和</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">终端</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">电阻，确保线路没有对地短路或者是对正</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">极</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">短路以及线路开路。之后还对总线的</span>CAN<span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">高</span>CAN<span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">低波形进行了测量，正常的总线波型是呈镜像显示的，并且没有杂波。因此判断安全带拉紧器模块损坏。更换</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">并</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">编码</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">后该故障点解决。自动巡航</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">功能</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">恢复。还有一个转向柱模块内部故障，这种故障，首先</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">检查</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">电源和接地，因为只有故障码，但是没有故障</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">现像</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">，并且转向柱的所有</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">功能都有</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">，包括灯光</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">、</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">雨刷</span><span style="box-sizing: border-box; outline: 0px !important;

outline: 0px !important; font-size: 11pt;">等等，并且能通讯</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">，因此判定为内部问题，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">更换后故障解决。</span></p><p></p>
