The front type-C interface (charging only) cannot be charged前排type-C接口(仅充电)不能充电

①General inspection一般检查
1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Check the front type-C interface (charging only) wiring harness for damage, breakage, etc.检查前排type-C接口(仅充电)线束是否存在损坏、断裂等现象。 3. Check the front type-C interface (charging only) harness connector for loose connection or damage.检查前排type-C接口(仅充电)线束接插件是否存在虚接、损坏等现象。 Are the test results normal?检查结果是否正常？ Yes → Go to step 2.是>>去步骤2。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
②Check fuse检查保险丝
	1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Check whether the fuse IF04 in the electrical box on the instrument panel is normal.检查仪表板电器盒中保险丝IF04是否正常。 IF04：7.5A Are the test results normal?检查结果是否正常？ Yes → Go to step 3.是>>去步骤3。 No → Replace the fuse with the same specification.否>>更换相同规格保险丝。
③Check the front type-C interface (charging only) power supply harness检查前排type-C接口(仅充电)供电线束
	1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Disconnect the front type-C interface (charging only) harness connector IP41.断开前排type-C接口(仅充电)线束接插件IP41。 3. Connect the negative terminal of the 12V battery and the power status is "ON".连接蓄电池负极，电源状态“ON”。 4. Use a digital multimeter to measure the voltage between pin 3 of the IP41 and ground.用数字万用表测量IP41的3号针脚与接地之间的电压。 Standard voltage value: about 14V标准电压值：约14V Are the test results normal?检查结果是否正常？ Yes → Go to step 4.是>>去步骤4。 No → Repair or replace the front type-C interface (charging only) power supply harness.否>>维修或更换前排type-C接口(仅充电)供电线束。
④Check the front type-C interface (charging only) grounding harness检查前排type-C接口(仅充电)接地线束
	1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Disconnect the front type-C interface (charging only) harness connector IP41.断开前排type-C接口(仅充电)线束接插件IP41。 3. Use a digital multimeter to measure the resistance between pin 1 of the IP41 and ground.用数字万用表测量IP41的1号针脚与接地之间的电阻。 Standard resistance value: <1标准电阻值：＜1 Ω Are the test results normal?检查结果是否正常？ Yes → Go to step 5.是>>去步骤5。 No → Repair or replace the front type-C interface (charging only) grounding harness.否>>维修或更换前排type-C接口(仅充电)接地线束。
⑤Replace the front type-C interface (charging only)更换前排type-C接口(仅充电)
1. Replace the front type-C interface (charging only) and check whether the fault is eliminated.更换前排type-C接口(仅充电)，检查故障是否排除。 Are the test results normal?检查结果是否正常？ Yes → Fault resolved.是>>故障排除。 No → Find the cause from other fault symptoms.否>>从其他故障现象查找原因。
