Fault code description故障码说明

DTC故障码(DTC)	Fault code description故障码描述	Possible cause of failure可能故障原因
C11B016	Actuator PBC failure - voltage is too low执行器PBC故障-电压过低	1. The supply voltage is lower than 8.5V1.供电电压低于8.5V

Troubleshooting steps故障诊断步骤

①Power-on inspection (taking the motor-integrated left rear caliper as an example)上电检查(以电机集成式左后卡钳为例)

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 motor integrated left rear caliper voltage检查电机集成式左后卡钳电压

1. Power status "ON".电源状态“ON”。 2. Perform parking brake operation.进行驻车制动操作。 3. Check whether the voltage of the motor-integrated left rear caliper is normal.检查电机集成式左后卡钳电压是否正常。 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 motor-integrated left rear caliper circuit.检修电机集成式左后卡钳线路。

③Replacement of motor-integrated left rear caliper更换电机集成式左后卡钳

1. Replace the new motor-integrated left rear caliper and check whether the fault code and symptoms are eliminated.更换新的电机集成式左后卡钳，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。

④Replace electronic parking control unit更换电子驻车控制单元

1. Replace the electronic parking control unit with a new one and check whether the fault code and symptoms are eliminated.更换新的电子驻车控制单元，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 electronic parking control unit, you need to use a diagnostic tool to recalibrate the electronic parking control unit.更换电子驻车控制单元后，需用诊断仪对电子驻车控制单元重新标定。
