 Power liftgate not working电动掀背门不工作

①Check power liftgate module fault codes检查电动掀背门模块故障码
1. The power status is "OFF" and the diagnostic tool is connected.电源状态“OFF”，连接诊断仪。
2. Read the fault code and check whether the power liftgate module has a fault code.读取故障码，检查电动掀背门模块是否有故障码。
Are the test results normal?检查结果是否正常？
Yes → Go to step 2.是>>去步骤2。
No → Carry out fault diagnosis according to the fault code.否>>按照故障码进行故障诊断。
②Check fuse检查保险丝
1. Power status "OFF".电源状态“OFF”。
2. Check whether the power liftgate module fuse is blown.检查电动掀背门模块保险丝是否熔断。
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 power liftgate module power circuit检查电动掀背门模块电源线路
Graphic
1. Power status "ON".电源状态“ON”。
2. Use a digital multimeter to measure the voltage between pin 13 of the power liftgate module connector BD89 and ground.用数字万用表测量电动掀背门模块接插件BD89的13号针脚与接地之间的电压。
Standard voltage value: about 14V标准电压值：约14V
Graphic
d. Use a digital multimeter to measure the voltage between pin 3 of the electric liftgate module connector BD90 and ground.d.用数字万用表测量电动掀背门模块接插件BD90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 power liftgate module power harness.否>>维修或更换电动掀背门模块电源线束。
④Check power liftgate module ground circuit检查电动掀背门模块接地线路
Graphic
1. Power status "OFF".电源状态“OFF”。
2. Disconnect power liftgate module connector BD89/BD90.断开电动掀背门模块接插件BD89/BD90。
3. Use a digital multimeter to measure the resistance between pin 23 of the BD89 and ground.用数字万用表测量BD89的23号针脚与接地之间的电阻。
Standard resistance value: <1标准电阻值：＜1 Ω
Graphic
d. Use a digital multimeter to measure the resistance between pin 10 of BD90 and ground.d.用数字万用表测量BD90的10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 power liftgate module ground harness.否>>维修或更换电动掀背门模块接地线束。
⑤Replacing the power liftgate module更换电动掀背门模块
1. Replace the electric liftgate module and check whether the fault is eliminated.更换电动掀背门模块，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → The system is normal.是>>系统正常。
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 electric liftgate module, you need to use a diagnostic tool to recalibrate the electric liftgate module.更换电动掀背门模块后，需用诊断仪进行电动掀背门模块重新标定。
