AQS sensor has short circuit or open circuit to power supplyAQS传感器对电源短路或开路
1. The sensor module harness is open or short-circuited to the battery.1.传感器模块线束开路或者短路到电池
Troubleshooting steps故障诊断步骤
①General inspection一般检查
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 whether the AQS sensor wire harness is damaged or broken.检查AQS传感器线束是否存在损坏、断裂等现象。
3. Check the AQS sensor harness connector for loose connection or damage.检查AQS传感器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 AQS sensor module circuit检查AQS传感器模块线路
1. Check whether the AQS sensor module circuit is short-circuited or open-circuited to the power supply.检查AQS传感器模块线路是否对电源短路或开路。
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 AQS sensor module wiring harness.维修或更换AQS传感器模块线束。
④Replace AQS sensor更换AQS传感器
1. Replace the AQS sensor with a new one and check whether the fault code and symptoms are eliminated.更换新的AQS传感器，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 5.去步骤5。
⑤Replacing the thermal management integrated module更换热管理集成模块
1. Replace the thermal management integrated module with a new one and check whether the fault code and symptoms are eliminated.更换新的热管理集成模块，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 thermal management integrated module, you need to use a diagnostic instrument to recalibrate the thermal management integrated module.更换热管理集成模块后，需用诊断仪对热管理集成模块重新标定。
