问：开启大灯时，发动机会降低发动机电源

两个原始代码是指扭矩转换器，包括控制电路和设备，尤其是锁定电磁阀。确定他们执行的维修情况的唯一方法是让他们向您展示最初的诊断结果（谴责一部分将以仪器读取或扫描工具结果的形式有记录证据）或实际向您展示，有缺陷的组件一旦从您的汽车上取出。在您的情况下，被引用的“离合器”是在密封的（焊接关闭）组件中，即扭矩转换器。因此，他们显然更换的是“扭矩转换器”作为整个组件，而不是“离合器”。如果他们告诉您他们取代了“离合器”，那么他们并不是特别有用或准确。顺便说一句，有一个访问面板，您可以瞥见转换器；如果是我，我会非常好奇地窥视那里，看看转换器是否真的更改了。我提到的原因是您提供的代码牵涉到其他控制组件，而不仅仅是离合器。这些其他组件中的一些代表了较不昂贵，更简单的修复。无论如何，要回答您的问题，在没有直接证据的情况下，很难就您是否被接受。 Going forward, by the way, you can minimize or eliminate that sort of problem by working one on one with "a" mechanic, as you would with YourMechanic professionals, because you can directly ask, "show me the evidence". These shops are huge bureaucracies and the notion that you are entitled to a reasonable account of what they are doing with your hard earned money is completely foreign to them. At any rate, the present code that reflects the reduced power issue typically is traced to a poor ground or electric power supply fault on specific CAN bus circuits. You can load test the battery and verify alternator output just in case, but it is likely a circuit trace will have to be performed to pinpoint the interruption on that CAN bus circuit(s). You need the Factory Service Manual wiring diagram to do that.
