Important notes on vehicle control systems有关整车控制系统的重要注意事项   Caution:注意： ♦  Repairs should be performed according to standard diagnostic procedures.维修应按照标准的诊断流程进行作业。 ♦  When it is detected that the components of the vehicle control system are damaged, they should be replaced as a whole, and disassembly and disassembly are strictly prohibited. Otherwise, the normal operation of other parts may be affected.当检测到整车控制系统零部件损坏，应整体更换，严禁进行分解、拆卸作业。否则可能影响到其他零部件的正常运行。 ♦  It is strictly prohibited to disassemble the vehicle controller.严禁对整车控制器进行分解。 ♦  Only parts specified by the manufacturer can be replaced, otherwise the normal operation of the system will not be guaranteed.只能更换厂家指定的零部件，否则将无法保证系统的正常工作。 ♦  Do not arbitrarily remove any parts of the system or its connectors from their installation positions to avoid damage or foreign matter such as moisture and oil entering the connectors and affecting the normal operation of the system.不要随意将系统的任何零部件或其接插件从其安装位置上拆下，以免损坏或水分、油污等异物进入接插件内，影响系统的正常工作。 ♦  When disconnecting or connecting the connector, the power supply must be in the "OFF" state, otherwise the electrical components may be damaged.当断开或连接接插件时，电源状态须置于“OFF”状态，否则可能会损坏电器元件。 ♦  If it is necessary to remove the 12V battery's negative cable or ground, the power supply must be set to "OFF" and all electrical loads must be turned off. After removing the negative ground wire for 60 seconds, other electrical appliances can be repaired.如有需要拆卸蓄电池负极电缆或搭铁时，需使电源状态置于“OFF”状态，且所有电气负载必须关闭，拆下负极搭铁线60s后，才可对其他电器进行维修。 ♦  The components of the vehicle control system have high reliability. When there is an abnormality in the vehicle or the drive motor, first check whether the relevant mechanical components are intact and whether the system connectors, wiring harnesses and ground wires are in good contact.整车控制系统的零部件可靠性较高，当整车或驱动电机出现异常时，首先检查相关的机械零部件是否完好，系统接插件、线束和搭铁线等接触是否良好。 ♦  Failures of the vehicle control system are mainly faults of the wiring harness and connectors. Generally, the wiring harness is broken, the connectors are in poor contact, the connector terminals are pulled out or not inserted in the end, and the components are grounded.整车控制系统的故障，主要是线束和接插件故障，一般为线束折断，接插件接触不良，接插件端子被拔出或没有插到底，零部件搭铁。 ♦  It is very rare for the wire harness to be broken in the middle, mostly at the connector, so the wire harness at the sensor and connector should be carefully checked.线束在中间折断是很罕见的，大都是在接插件处断开，因此尤其应仔细检查传感器和接插件处的线束。 ♦  Poor contact may be caused by corrosion of the connector terminals, external dirt entering the terminals, or reduced contact pressure between the connector plug and the socket. Separating the connector and plugging it back in again can change its connection status and restore normal contact.接触不良可能由于接插件端子锈蚀、外界脏污进入端子，或接插件插头与插座之间接触压力降低所致。把接插件分开再重新插上，可改变它的连接状况，恢复正常接触。 ♦  During fault diagnosis, if no abnormality occurs when checking the wiring harness and connectors, and the fault disappears after reconnection, it can be considered that the wiring or connector is faulty.在故障诊断时，检查线束和接插件时没有发生不正常情况，重新连接以后故障消失，则可认为配线或接插件有故障。   Caution:注意： ♦  Do not use a fine needle to pierce the wiring harness to check the system electrical signals.不能使用细针刺破线束的方法检查系统电信号。 ♦  When installing and handling the sensor or controller, you must handle it with care to ensure that it is not damaged. Any impact or drop may cause great damage to its performance.安装搬运传感器或控制器时，为保证其不受损坏，必须轻拿轻放，任何冲击、跌落，对其性能可能造成极大的损坏。 ♦  Fixing bolts or nuts should be tightened to the specified torque.应按规定力矩拧紧固定螺栓或螺母。 ♦  When performing arc welding on a vehicle, the positive and negative cables of the 12V battery should be disconnected, and the vehicle controller should be disassembled if necessary to avoid damage to the vehicle controller caused by high-voltage electricity during arc welding. When performing body repair work near vehicle controllers or sensors, special care should be taken to avoid damaging these electronic components.在对车辆进行电弧焊时，应断开蓄电池正、负极电缆，如有必要可拆卸整车控制器，避免电弧焊接时高压电对整车控制器造成损坏。在靠近整车控制器或传感器的地方进行车身修理作业时，应特别小心，以免碰坏这些电子元件。 ♦  When installing or disassembling the vehicle controller, the operator should ground himself first, otherwise the static electricity from the human body will damage the vehicle controller circuit.在安装或拆卸整车控制器时，操作人员应先使自己搭铁，否则，人体的静电会损坏整车控制器电路。 ♦  The power supply systems used in automobiles are all negative-pole grounded. When installing the 12V battery, special attention should be paid to not connecting the positive and negative poles in reverse to avoid damaging the electronic components.汽车采用的供电系统均为负极搭铁，安装蓄电池时，要特别注意正、负极不可接反，以免损坏电子元件。 ♦  When a system fault occurs, after the diagnostic tool clears the fault code, if the system fault is not eliminated and the fault code reading step is performed again, the fault code will remain until the fault is eliminated. At the same time, historical fault codes should also be cleared after the repair is completed.当系统出现故障时，在诊断仪清除故障代码后，若系统故障不排除，再次执行故障代码读取步骤时，故障代码会一直存在，直到故障被排除。同时，维修完成也应清除历史故障代码。
