九哥黑哥各路大侠来帮帮看

2012的最后一天，我开车出去买菜回来，车停在车库，发动机继续运转。我上楼拿点东西下来，停了发动机，一会后再想启动，结果启动不了，只有点火声没发动机声，五颜六色邓都亮了，显示have your dealer to check the brake. 再试着发动有时又显示check the VSC system。我都要拖车了，再试，又行了，后来再没碰到这问题。

今天送去车行检查，结果也没发现啥不对，只是读码发现U0100，他们说如果再有此事发生再送去。这报告说：Scanned vehicle found U0100 lost communication with ECM/PCM "A" present on system. No lights on dash. code is set due to a voltage reading higher than 9.5v while travelling more than 5km or there is a loss of communication with the ECU for more than 3 seconds.......

.....
Mil on triggering condition for U0100:
IG voltage between 9-16v
Ignition on. Engine off
EPS ECU detects no communication from Engine ECM for more than 0.
.....
Suggestion: Disregard this code when diagnosing other vehicle concern

大家觉得这会是啥事？有人说趁车子还在保修期尽快去叫dealer换ECU， 就发生过一次这问题dealer可能换么?

建议检查线路，我有个朋友曾经遇到类似问题，当年被CT黑了说要换starter，结果问题还存在，找了另外一个车行发现就是有一根线松了（造成仪表盘各个灯乱闪）

楼上说的

某根线松了或者锈/被腐蚀之后信号不好。

谢谢，卖这车的ｓａｌｅ回ｅｍａｉｌ了：
I talked to some of the techs this morning about your issue before I got your email. They were aware of your error code that you got. You are not the first. They were quite adamant in telling me that you have nothing to worry about. It only happens in the situation you described and immediately fixes itself. It is a rare fluke issue that happens with the computers communicating with each other. They way they described it was it was like your internet losing signal at bootup for a second and giving an error. A simple refresh (restart the car) takes care of the issue.

I do suggest that you still come in and talk to them personally though in case I did not relay the proper information but it sounds for now that it is nothing to worry about. They would be able to answer for sure and would happily replace anything that needs replacing if need be.

就出现一次，现在正常，去车行他们也就这样说，怎么叫他们修？

CAN "Lost Communication" DTCs U0100 and U0129 (S-SB-0014-10)

Some 2008 – 2009 model year Scion xB vehicles may exhibit an intermittent condition where multiple Malfunction Indicator Lights (MIL) remain illuminated after start up, and the power steering system will enter the fail safe mode. The vehicle may return to normal after cycling the key.
The following DTCs will be stored in the EPS ECU:
• U0100 – Lost Communication with ECM/PCM “A”
• U0129 – Lost Communication with Brake System Control Module
The following DTCs may be stored in the VSC (ABS) system:
• U0073 – Control Module Communication Bus OFF
• U0123 – Lost Communication with Yaw Rate Sensor Module
• U0124 – Lost Communication with Lateral Acceleration Sensor Module
• U0126 – Lost Communication with Steering Angle Sensor Module
The EPS ECU software has been updated to prevent this condition. Replace the EPS ECU if DTCs
U0100 and U0129 are stored in the EPS ECU.


这个是搜到的Toyota Scion上的问题，既然都是toyota的车，ECU应该差不多，解决问题也差不多
所以你的车应该也有ECU firmware刷新

话说，现在车越来越复杂，出点电脑问题也正常。。。。

我原来135有一次打着了狂抖，跟地震一样，档杆左右能有15度的摆幅，engine light狂闪。
关掉从新打火就好了，哈哈，我连dealer都没去，无所谓啦。


还听说过方向盘上调音量，窗玻璃会下来，各种莫名其妙的问题哈哈

哥们，有那么夸张吗？左右十五度，你那是拨浪鼓呀？

 

[sydzs]

那辆135是不是Transformer变的，你不知道啊

一点不夸张，一通狂抖
