Washing motor not working洗涤电机不工作

①General inspection一般检查
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 2.否>>去步骤2。
②Check combination switch and clock spring assembly检查组合开关与时钟弹簧总成
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 3.否>>去步骤3。
③Check 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 and washer motor wiring harness for damage, breakage, etc.检查集成式车身控制模块和洗涤电机线束是否存在损坏、断裂等现象。 3. Check whether the integrated body control module and the washer motor wiring harness connector are connected or damaged.检查集成式车身控制模块和洗涤电机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 4.是>>去步骤4。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
④Check 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 if fuse IF53 in the electrical box on the instrument panel is normal.检查仪表板电器盒中保险丝IF53是否正常。 IF53：15A Are the test results normal?检查结果是否正常？ Yes → Go to step 5.是>>去步骤5。 No → Replace the fuse with the same specification.否>>更换相同规格保险丝。
⑤Check washing power supply检查洗涤电源
	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 integrated body control module harness connector FB51.断开集成式车身控制模块线束接插件FB51。 3. Connect the negative terminal of the 12V battery.连接蓄电池负极。 4. Use a digital multimeter to measure the voltage between pin 1 of FB51 and ground.用数字万用表测量FB51的1号针脚与接地之间的电压。 Standard voltage value: about 12.5V标准电压值：约12.5V 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 washing power wiring harness.否>>维修或更换洗涤电源线束。
⑥Check the washing motor power supply wiring harness检查洗涤电机供电线束
	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 washer motor harness connector FB37 and integrated body control module harness connector FB51.断开洗涤电机线束接插件FB37和集成式车身控制模块线束接插件FB51。 3. Use a digital multimeter to measure the resistance between pin 1/2 of FB37 and pin 3/2 of FB51.用数字万用表测量FB37的1/2号针脚与FB51的3/2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 washing motor power supply harness.否>>维修或更换洗涤电机供电线束。
⑦Replace washing motor更换洗涤电机
1. Replace the washing motor and check whether the fault is eliminated.更换洗涤电机，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。
⑧Replacing 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。
