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。 |
|
♦
|
It is strictly prohibited to disassemble the body control module.严禁对车身控制模块进行分解。 |
|
♦
|
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。 |

Failures of the body control system are mainly faults of the wiring harness and connectors. Generally, the wiring harness is broken, the connectors have poor contact, the connector terminals are pulled out or are not inserted in the bottom, and the components are grounded. 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.车身控制系统的故障，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。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。 |
|
♦
|
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。 |
|
♦
|
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 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。 |
