DTC故障码(DTC)	Fault code description故障码描述	Possible cause of failure可能故障原因
B1ED016	There is a fault in the corner radar power supply, and the circuit voltage is lower than the threshold.角雷达电源存在故障，电路电压低于门槛值	1. The voltage is lower than the diagnostic voltage lower limit1.电压低于诊断电压下限

Troubleshooting steps故障诊断步骤

①Power-on inspection (take the left rear blind spot monitoring main sensor as an example for inspection)上电检查(以左后盲区监测主传感器为例进行检查)
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 12V battery voltage检查蓄电池电压
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. Use a digital multimeter to measure the voltage between the positive and negative terminals of the 12V battery.用数字万用表测量蓄电池正、负极之间的电压。 Standard voltage value: about 12.5V标准电压值：约12.5V 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 Go to step 3.去步骤3。
③Check DCDC output voltage检查DCDC输出电压
1. Power status "ON".电源状态“ON”。 2. Use a digital multimeter to measure the voltage between the positive and negative terminals of the 12V battery.用数字万用表测量蓄电池正、负极之间的电压。 Standard voltage value: about 14V标准电压值：约14V Are the test results normal?检查结果是否正常？ Yes是 Charge the 12V battery and replace it if necessary.对蓄电池进行充电，必要时更换蓄电池。 No否 Inspect the DCDC system and wiring harness.检修DCDC系统及线束。
④Check the left rear blind spot monitoring main sensor power supply line检查左后盲区监测主传感器供电线路
	1. The vehicle is powered on.车辆上电。 2. Use a multimeter to measure the voltage between pin 1 of the RB03 and ground.使用万用表测量RB03的1号针脚与接地之间的电压。 Standard voltage value: about 14V标准电压值：约14V 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 Inspect and repair the power supply line of the left rear blind spot monitoring main sensor.检修左后盲区监测主传感器供电线路。
⑤Replace the left rear blind spot monitoring main sensor更换左后盲区监测主传感器
1. Replace with a new left rear blind spot monitoring main sensor and check whether the fault code and symptoms are eliminated.更换新的左后盲区监测主传感器，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 monitoring the left rear blind spot, you need to use a diagnostic instrument to recalibrate the main sensor for monitoring the left rear blind spot.更换左后盲区监测主传感器后，需用诊断仪对左后盲区监测主传感器重新标定。
