Troubleshooting steps故障诊断步骤

①Power on check上电检查
1. Power status is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”,断开蓄电池负极。 2. Check whether the wire harness of the mobile phone's wireless charging module is damaged or broken.检查手机无线充电模块线束是否存在损坏、断裂等现象。 3. Check whether the wire harness connector of the mobile phone wireless charging module is damaged or has a loose connection.检查手机无线充电模块线束接插件是否存在损坏、虚接等现象。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 2.去步骤2。 No否 Repair or replace faulty wiring harness or connector.维修或更换故障线束或接插件。
②Power on check上电检查
1. Repower the vehicle, use the diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.车辆重新上电，使用诊断仪读取并清除故障码，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 3.去步骤3。
③Check the power supply harness of the mobile phone wireless charging module检查手机无线充电模块供电线束
1. Power status 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 mobile phone wireless charging module harness connector CN03 and unplug the fuse IF49 in the instrument panel electrical box.断开手机无线充电模块线束接插件CN03，拔下仪表板电器盒保险丝IF49。 3. Use a multimeter to measure the resistance between pin 1/2 of CN03 and the power output of the fuse IF49 socket.用万用表测量CN03的1/2号针脚与保险丝IF49插座电源输出端之间的电阻。 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是 Go to step 4.去步骤4。 No否 Repair or replace the faulty wiring harness.维修或更换故障线束。
④Check the mobile phone wireless charging module grounding harness检查手机无线充电模块接地线束
	1. Power status 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 mobile phone wireless charging module harness connector CN03.断开手机无线充电模块线束接插件CN03。 3. Use a multimeter to measure the resistance between pin 3/8 of CN03 and ground.用万用表测量CN03的3/8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是 Go to step 5.去步骤5。 No否 Repair or replace the faulty wiring harness.维修或更换故障线束。
⑤Replace the mobile phone wireless charging module更换手机无线充电模块
1. Replace with a new mobile phone wireless charging module and check whether the fault code and symptoms are eliminated.更换新的手机无线充电模块，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Look for causes from other symptoms.从其他症状查找原因。   Caution:注意： ♦  After replacing the mobile phone wireless charging module, you need to use a diagnostic tool to recalibrate the mobile phone wireless charging module.更换手机无线充电模块后，需用诊断仪对手机无线充电模块重新标定。
