Possible cause of failure可能故障原因
B1ED128
There is a fault in the time synchronization module (with ADC_SOC), and the signal offset is out of range.时间同步模块（与ADC_SOC）存在故障，信号偏移量超范围
1. ADC_SOC time synchronization error (Note: The actual sender of ADC SOC related signals in the communication matrix is the ADC MCU. When troubleshooting, please locate the ADC MCU)1.ADC_SOC时间同步错误（注：通讯矩阵中涉及ADC SOC的相关信号，实际发出方为ADC的MCU，排查问题时请定位到ADC的MCU）
Troubleshooting steps故障诊断步骤
①Power 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 2.去步骤2。
②Check CAN communication of autonomous driving domain controller检查自动驾驶域控制器CAN通讯
1. Check whether CAN communication of the autonomous driving domain controller is normal.检查自动驾驶域控制器CAN通讯是否正常。
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 Inspect the CAN communication harness.检修CAN通讯线束。
③Check the Autopilot Domain Controller检查自动驾驶域控制器
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 the diagnostic tool to check whether the autonomous driving domain controller is normal.使用诊断仪检查自动驾驶域控制器是否正常。
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 Troubleshoot the autonomous driving domain controller.检修自动驾驶域控制器。
④Replace the main sensor for blind spot monitoring更换盲区监测主传感器
1. Replace the main blind spot monitoring sensor with a new one and check whether the fault code and symptoms are eliminated.更换新的盲区监测主传感器，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 Look for causes from other symptoms.从其他症状查找原因。
  Caution:注意：
♦  After replacing the main sensor for blind spot monitoring, you need to use a diagnostic instrument to recalibrate the main sensor for blind spot monitoring.更换盲区监测主传感器后，需用诊断仪对盲区监测主传感器重新标定。
