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
C15E000	Brake pedal position sensor "A"/"B" related faults制动踏板位置传感器“A”/“B”相关故障	1. The deviation between the pedal stroke sensors exceeds the threshold/the driver depresses the accelerator pedal and brake pedal at the same time1.踏板行程传感器之间偏差超过阈值/驾驶员同时踩下油门踏板和制动踏板

Troubleshooting steps故障诊断步骤

①Operation check操作检查

1. Check whether the driver depresses the accelerator pedal and brake pedal at the same time.检查驾驶员是否存在同时踩下油门踏板和制动踏板的行为。 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 Avoid such abnormal operations.避免此类非正常操作。

②Power on check上电检查

1. Power on the vehicle again and check whether the fault code and symptoms are eliminated.车辆重新上电，检查故障码及症状是否排除。 2. After the vehicle is powered on again, wait 5 seconds, then press and release the brakes several times.车辆重新上电后等待5秒，多次踩下并释放刹车。 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。

③Replacing 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。
