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 the circulation actuator wiring harness for damage, breakage, etc.检查循环执行器线束是否存在损坏、断裂等现象。
|
|
3. |
Check whether there is a loose connection or damage to the circulation actuator wiring harness connector.检查循环执行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?
|
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。 |
|
|
③Check the cycle actuator potential feedback circuit检查循环执行器电位反馈线路
|
|
1. |
Check whether the cycle actuator potential feedback line is short-circuited or open-circuited to ground.检查循环执行器电位反馈线路是否对地短路或开路。 |
Are the test results normal?检查结果是否正常?
|
No否 |
Repair or replace the cycle actuator potential feedback harness.维修或更换循环执行器电位反馈线束。 |
|
|
④Replace cycle actuator更换循环执行器
|
|
1. |
Replace the cycle actuator with a new one and check whether the fault code and symptoms are eliminated.更换新的循环执行器,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。 |
|
|
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。 |
