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
C103001	Braking system fading failure (brake disc temperature is too high)制动系统衰减故障（制动盘温度过高）	1. Braking system overheating (brake disc overheating or brake fluid overheating)1.制动系统过热（制动盘过热或者制动液过热）

Troubleshooting steps故障诊断步骤

①Operation check操作检查

1. Check whether the driver continues to drive vigorously or uses the brakes for a long time.检查驾驶员是否连续激烈驾驶或长时间使用刹车。 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 Reduce such abnormal operations.减少此类非正常操作。

②Check brake fluid检查制动液

1. Check whether the brake fluid has deteriorated and whether the water content is too high.检查制动液是否变质、含水量是否过高。 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 Replace brake fluid.更换制动液。

③Standing inspection静置检查

1. Let the vehicle sit for a period of time, wait until the brake disc has completely cooled, and check whether the fault code and symptoms have been eliminated.车辆静置一段时间，待制动盘完全冷却，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。
