The high beam is turned on, the high beam is not on远光灯打开，远光灯都不亮

①Check the wiring harness connector检查线束接插件
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 integrated body control module wiring harness for damage, breakage, etc.检查集成式车身控制模块线束是否存在损坏、断裂等现象。 3. Check the integrated body control module wiring harness connector for loose connections or damage.检查集成式车身控制模块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 the combination switch and clock spring assembly fault code检查组合开关与时钟弹簧总成故障码
1. Use a diagnostic tool to read the fault code of the combination switch and clock spring assembly, and check whether there is a fault in the combination switch and clock spring assembly.使用诊断仪读取组合开关与时钟弹簧总成故障码，检查组合开关与时钟弹簧总成是否存在故障。 Are the test results normal?检查结果是否正常？ Yes → Go to step 3.是>>去步骤3。 No → Troubleshoot the fault of the combined switch and clock spring assembly according to the fault code.否>>根据故障码排除组合开关与时钟弹簧总成故障。
③Check integrated body control module fault codes检查集成式车身控制模块故障码
1. Use the diagnostic tool to read the fault code of the integrated body control module and check whether there is a fault in the integrated body control module.使用诊断仪读取集成式车身控制模块故障码，检查集成式车身控制模块是否存在故障。 Are the test results normal?检查结果是否正常？ Yes → Go to step 4.是>>去步骤4。 No → Troubleshoot the integrated body control module fault according to the fault code.否>>根据故障码排除集成式车身控制模块故障。
④Check high beam power supply检查远光灯电源
	1. The power status is "ON" and the high beam function is turned on.电源状态“ON”，开启远光灯功能。 2. Use a digital multimeter to measure the voltage between pin 5 of the left front combination light harness connector FB39 and ground.用数字万用表测量左前组合灯线束接插件FB39的5号针脚与接地之间的电压。 Standard voltage value: about 12V标准电压值：约12V
	e. Use a digital multimeter to measure the voltage between pin 5 of the right front combination light harness connector FB38 and ground.e.用数字万用表测量右前组合灯线束接插件FB38的5号针脚与接地之间的电压。 Standard voltage value: about 12V标准电压值：约12V 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 high beam power wiring harness.否>>维修或更换远光灯电源线束。
⑤Check the high beam ground harness检查远光灯接地线束
	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 left front combination light harness connector FB39 and the right front combination light harness connector FB38.断开左前组合灯线束接插件FB39与右前组合灯线束接插件FB38。 3. Use a digital multimeter to measure the resistance between pin 4 of FB39 and ground.用数字万用表测量FB39的4号针脚与接地之间的电阻。 Standard resistance value: <1标准电阻值：＜1 Ω
	d. Use a digital multimeter to measure the resistance between pin 4 of FB38 and ground.d.用数字万用表测量FB38的4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 6.是>>去步骤6。 No → Repair or replace the high beam grounding harness.否>>维修或更换远光灯接地线束。
⑥Replace front combination lamp更换前组合灯
1. Replace the front combination lamp and check whether the fault is eliminated.更换前组合灯，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 → Go to step 7.否>>去步骤7。
⑦Replacing the integrated body control module更换集成式车身控制模块
1. Replace the integrated body control module and check whether the fault is eliminated.更换集成式车身控制模块，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。   Caution:注意： ♦  After replacing the integrated body control module, you need to use a diagnostic tool to recalibrate the integrated body control module.更换集成式车身控制模块后，需用诊断仪对集成式车身控制模块重新标定。
