Troubleshooting steps故障诊断步骤

①Power on check上电检查

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 left front in-line wheel speed sensor type检查左前直插式轮速传感器类型

1. Check whether the left front in-line wheel speed sensor is the correct type.检查左前直插式轮速传感器类型是否正确。 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 the left front in-line wheel speed sensor with the correct type.更换正确类型的左前直插式轮速传感器。

③Check the integrated brake control unit software configuration information检查集成式制动控制单元软件配置信息

1. Check whether the software configuration information of the integrated brake control unit is consistent with the hardware configuration.检查集成式制动控制单元软件配置信息和硬件配置是否一致。 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 Re-flash the correct configuration information.重新刷写正确的配置信息。

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。
