Troubleshooting steps故障诊断步骤

①General inspection一般检查

1. Check whether the ambient temperature is too high.检查环境温度是否过高。 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 Move the vehicle to a cool area to cool down.将车辆移至阴凉处进行散热。

②Operation check操作检查

1. Check whether the driver performs frequent braking operations.检查驾驶员是否存在频繁制动操作。 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 Reduce the braking frequency or leave the vehicle stationary; if the fault persists, go to step 3.降低制动频率或车辆静置；若故障依然存在，去步骤3。

③Power on check上电检查

1. Power on the vehicle again, release the brake pedal twice, and wait 30 seconds.车辆重新上电，踩松制动踏板两次，等待30秒。 2. Use a diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.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 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。
