④Check the power circuit of the power liftgate drive lever Hall sensor检查电动掀背门驱动杆霍尔传感器电源线路
	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 power liftgate drive lever harness connector BD96 and the power liftgate module harness connector BD89.断开电动掀背门驱动杆线束接插件BD96和电动掀背门模块线束接插件BD89。 3. Use a digital multimeter to measure the resistance between pin 10 of BD96 and pin 18 of BD89.用数字万用表测量BD96的10号针脚与BD89的18号针脚之间的电阻。 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 power liftgate drive lever Hall sensor power harness.否>>维修或更换电动掀背门驱动杆霍尔传感器电源线束。
⑤Check the power liftgate drive lever Hall sensor ground circuit检查电动掀背门驱动杆霍尔传感器接地线路
	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 power liftgate drive lever harness connector BD96 and the power liftgate module harness connector BD89.断开电动掀背门驱动杆线束接插件BD96和电动掀背门模块线束接插件BD89。 3. Use a digital multimeter to measure the resistance between pin 4 of BD96 and pin 14 of BD89.用数字万用表测量BD96的4号针脚与BD89的14号针脚之间的电阻。 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 power liftgate actuator lever Hall sensor ground harness.否>>维修或更换电动掀背门驱动杆霍尔传感器接地线束。
⑥Check the electric liftgate drive lever Hall sensor signal circuit检查电动掀背门驱动杆霍尔传感器信号线路
	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 power liftgate drive lever harness connector BD96 and the power liftgate module harness connector BD89.断开电动掀背门驱动杆线束接插件BD96和电动掀背门模块线束接插件BD89。 3. Use a digital multimeter to measure the resistance between pin 3/9 of BD96 and pin 22/1 of BD89.用数字万用表测量BD96的3/9号针脚与BD89的22/1号针脚之间的电阻。 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 7.是>>去步骤7。 No → Repair or replace the power liftgate drive lever Hall sensor signal harness.否>>维修或更换电动掀背门驱动杆霍尔传感器信号线束。
⑦Replace power liftgate drive lever更换电动掀背门驱动杆
1. Replace the electric liftgate drive lever with a new one and check whether the fault is eliminated.更换新的电动掀背门驱动杆，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 8.否>>去步骤8。
