你好
具体故障码发一下
![mechanic_avatar]()
视频暂不支持播放
![mechanic_avatar]()
车身报的故障码
拍照！
![mechanic_avatar]()
发动机进不去
不要视频
能着车吗？
![mechanic_avatar]()
着不了 打车没反应
发动机模块能找到吗？
![mechanic_avatar]()
换过
还有别的码吗？
通讯问题需要测该模块的电源搭铁和网线
![mechanic_avatar]()
好几个系统都报的与发动机失去通讯

大哥这个车的通讯线是直通道诊断口的吗
都跟发动机电脑通讯中断就直接测发动机电脑插头吧
网线诊断接口跟动力网网关模块通讯，不一定直接连发动机
![mechanic_avatar]()
大哥你知道这个车的网关模块是哪一个吗
一般是配电盒，一会查查
我感觉还是该从发动机电脑入手
![mechanic_avatar]()
是这个吗
这个是前控制模块
发动机电脑的电源搭铁，还有网线电压多少？
![mechanic_avatar]()
他这个网线是那种的呀
![mechanic_avatar]()
是CAN吗
对
![mechanic_avatar]()
它这个车变速箱和发动机都在一起 变速箱就能通讯
嗯，四个插头，我记得两个发动机的，两个变速器的
![mechanic_avatar]()
好的 我先看供电吧
![mechanic_avatar]()
在吗大哥
![mechanic_avatar]()
你有这个OBD端子图吗
