5.Plunger failure5.Plunger故障
Troubleshooting steps故障诊断步骤
①Check brake fluid level检查制动液液位
1. Check whether the brake fluid is low.检查制动液是否过少。
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 Add brake fluid after confirming there are no leaks.确认无泄漏后添加制动液。
②Check brake lines检查制动管路
1. Check the brake pipeline for damage, leakage, etc.检查制动管路是否存在破损、泄露等现象。
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 Repair or replace faulty parts.维修或更换故障部件。
③Check brake wheel cylinder检查制动轮缸
1. Check the brake wheel cylinder for damage, leakage, etc.检查制动轮缸是否存在破损、泄露等现象。
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 Replace brake wheel cylinder.更换制动轮缸。
④Power 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。
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 5.去步骤5。
⑤Replacing 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。
