When the brake pedal is depressed, the vehicle cannot receive high-voltage electricity.踩下制动踏板，车辆无法上高压电

①General inspection一般检查

1. Check whether the smart key is legal and valid.检查智能钥匙是否合法有效。 2. Check whether the smart key is placed correctly.检查智能钥匙放置位置是否正确。 Are the test results normal?检查结果是否正常？ Yes → Go to step 2.是>>去步骤2。 No → Place the smart key in the correct position. If the fault persists, check whether the smart key is a legal smart key for the vehicle.否>>将智能钥匙放置正确位置，若故障仍然存在，检查智能钥匙是否是车辆的合法智能钥匙。

②Check fault codes检查故障码

1. Power status "OFF".电源状态“OFF”。 2. Connect the diagnostic tool.连接诊断仪。 3. Power status "ON".电源状态“ON”。 4. Use a diagnostic tool to read the fault code and check whether there is a fault.用诊断仪读取故障码，检查是否存在故障。 Check if there is a fault code?检查是否存在故障码？ Yes → Troubleshoot related faults according to the fault code.是>>根据故障码排除相关故障。 No → Go to step 3.否>>去步骤3。

③Check 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. Power status "OFF".电源状态“OFF”。 2. Connect the diagnostic tool.连接诊断仪。 3. Power status "ON".电源状态“ON”。 4. Use a diagnostic tool to read the fault code of the combination switch and clock spring assembly to check whether there is a fault.用诊断仪读取组合开关与时钟弹簧总成故障码，检查是否存在故障。 Check if there is a fault code?检查是否存在故障码？ Yes → Troubleshoot the fault of the combined switch and clock spring assembly according to the fault code.是>>根据故障码排除组合开关与时钟弹簧总成故障。 No → Go to step 4.否>>去步骤4。

④Check high voltage electrical检查高压电气

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 each high-voltage electrical component for faults.检查各高压电气部件是否存在故障。 3. Check whether each high-voltage wiring harness is connected correctly.检查各高压线束是否连接正确。 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 faulty wiring harness or connector or high-voltage electrical component.否>>维修或更换故障线束或接插件或高压电气部件。

⑤Check 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 combination switch and clock spring assembly, and the integrated body control module wiring harness for damage, breakage, etc.检查组合开关与时钟弹簧总成、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 combination switch, clock spring assembly, and integrated body control module harness connector for loose connections or damage.检查组合开关与时钟弹簧总成、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 6.是>>去步骤6。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。

⑥Replacing 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。
