PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is an ECU or DCU harness defined by the connector housing?ECU 或 DCU 线束可以只按连接器壳体定义吗？
No. The exact controller, cavity schedule, terminal and seal system, wire specifications, branches, loads, network topology, protection and mounting zone define the assembly.不能。准确控制器、孔位表、端子与密封体系、线材规格、分支、负载、网络拓扑、保护与安装区域共同定义组件。
Can you build from an existing damaged sample?可以依据损坏的现有样品制作吗？
A sample can support geometry and connector identification, but hidden splices, materials, shielding and earlier repairs require independent confirmation. Electrical data and the intended function are still needed.样品有助于确认几何与连接器，但隐藏接续、材料、屏蔽和既往维修仍需独立确认，同时仍需电气资料与预期功能。
Can a Y harness keep the ECU connected while measurements are taken?Y 型线束可以在保持 ECU 连接时进行测量吗？
Yes, when the branch topology, stub length, instrument loading, shielding, exposed-point protection and connected-state test method are approved for the target circuits.可以，但需针对目标回路批准分支拓扑、支线长度、仪器负载、屏蔽、裸露测点保护与连接状态测试方法。
