Left rear steering A light feedback line open circuit左后转向A灯反馈线开路
1. There is a problem with the light module1.灯组模块出问题
2. There is a problem with the feedback line wiring2.反馈线路接线出问题
Troubleshooting steps故障诊断步骤
①General inspection一般检查
1. Power status "OFF".电源状态“OFF”。
2. Check the left rear combination lamp wiring harness for damage, breakage, etc.检查左后组合灯线束是否存在损坏、断裂等现象。
3. Check the left rear combination lamp wiring harness connector for damage, loose connection, etc.检查左后组合灯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。
②Check left rear turn signal A feedback harness检查左后转向灯A反馈线束
Graphic
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 the left rear combination light harness connector BD87 and the integrated body control module harness connector BD57.断开左后组合灯线束接插件BD87和集成式车身控制模块线束接插件BD57。
3. Use a multimeter to measure the resistance between pin 2 of the BD87 and pin 7 of the BD57.使用万用表测量BD87的2号针脚与BD57的7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是 Go to step 3.去步骤3。
No否 Repair or replace the faulty wiring harness.维修或更换故障线束。
③Replace left rear combination light更换左后组合灯
1. Replace the left rear combination lamp with a new one and check whether the fault code and symptoms are eliminated.更换新的左后组合灯，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 4.去步骤4。
④Replacing the integrated body control module更换集成式车身控制模块
1. Replace with a new integrated body control module and check whether the fault code and symptoms are eliminated.更换新的集成式车身控制模块，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 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。
