font-size: 11pt;">万到</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">9</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">万公里和</span><span style="box-sizing: border-box;

font-size: 11pt;">19</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">万公里这两个阶段数据会错乱，只需要对仪表进行数据改写，把仪表里程数跳过这两个阶段的</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">范围即可。而这个车曲轴箱位置</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">(CKP)</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">系统变化未读出是因为曲轴位置（</span><span style="box-sizing: border-box;

outline: 0px !important; font-size: 11pt;">计算得到的偏差可使发动机控制模块（</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">ECM</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">）精确地补偿基准期偏差</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;">从而使发动机控制模块能在更宽的发动机转速和负荷范围内检测缺火事件。</span> <span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">完成读入程序后，发动机控制模块存储曲轴位置系统偏差值。</span> <span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">如果实际曲轴位置偏差不在发动机控制模块中保存的曲轴位置系统偏差补偿值范围内，便会设置该故障码。在对外围的线路电压</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;">波形</span><span style="box-sizing: border-box; outline: 0px !important;

outline: 0px !important; font-size: 11pt;">对曲轴位置学习一下便可解决。而第二级数据连接故障码是因为连接到</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">Class 2</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">串行数据电路上的模块，在车辆正常工作过程中，会监视串行数据通信情况。操作信息和指令在模块之间相互交换。当一个模块接到一条关键的工作参数信息时，该模块会记录信息发送模块的识别号，以判断其是否处于正常状态下。关键的工作参数是指，若未收到该参数时，模块必须使用默认值来替代该参数。如果在串行数据通信刚开始的大约头</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">5</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">秒钟时间内，某个模块不能将识别号与至少一个关键参数进行关联，则设置</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">DTC U1000</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">或者</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">U1255</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">。当多个关键参数与识别号不关联时，该故障诊断</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">码仅报告</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">一次。出现此类故障时我们依然要对外围线路进行排查，发现外围线路匀在正常范围内。便判断仪表损坏，为了验证仪表损在，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">再</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">次读取牵引数据时发现数据的牵引力控制系统警告灯是关闭的，而仪表却点</span><span style="box-sizing: border-box;

font-size: 11pt;">，于是确认是仪表的问题，</span><span style="box-sizing: border-box; outline: 0px !important; font-size: 11pt;">更换仪表，故障排除。</span></p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88);
