		2. Caliper assembly failure2.卡钳总成故障
		3. Control unit failure3.控制单元故障

Troubleshooting steps故障诊断步骤

①General inspection一般检查

1. Check whether the brake disc, brake pad and right rear actuator are assembled normally.检查制动盘、刹车片、右后执行机构装配是否正常。 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 Reassemble.重新装配。

②Power on check上电检查

1. Clear the fault code, power on and off again, perform clamping and release operations, and check whether the fault code and symptoms are eliminated.清除故障码，重新上下电，进行夹紧释放操作，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 3.去步骤3。

③Check the motor-integrated right rear caliper assembly检查电机集成式右后卡钳总成

1. Replace the motor-integrated right rear caliper assembly with a new one, and check whether the fault code and symptoms are eliminated.更换新的电机集成式右后卡钳总成，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 brake control unit更换集成式制动控制单元

1. Replace with a new integrated brake control unit and check whether the fault code and symptoms are eliminated.更换新的集成式制动控制单元，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 integrated brake control unit, you need to use a diagnostic tool to recalibrate the integrated brake control unit.更换集成式制动控制单元后，需用诊断仪对集成式制动控制单元重新标定。 ♦  After replacing the integrated brake control unit, the brake line bleeding operation is required.更换集成式制动控制单元后，需进行制动管路排气操作。
