Most modern vehicles are equipped with ananti-lock braking system (ABS)。防锁制动系统是一项现代安全功能，可大大提高制动系统的有效性，尤其是在不利条件下。它的工作方式使驾驶员无需特殊输入即可获得最大的制动潜力。
The function of the anti-lock brake system is to allow the braking system to operate at the maximum potential, for a given system, and it does this by modulating the pressure in the braking system to allow the wheels to keep from locking up under hard braking. An anti-lock braking system is especially useful during very hard braking events to avoid anaccident，当雨水潮湿时，它们会被雪覆盖，道路冰冷，或者在松散的驾驶表面（例如污垢或砾石）上。
系统通过传感器，电动伺服器/电动机和控制装置的组合，感觉到轮子锁定，并在一秒钟内以制动压力进行校正。防锁系统旨在检测车轮锁定，释放足够的压力以使车轮再次转动，并且在制动系统中仍然保持尽可能多的压力，而无需驾驶员必须手动进行任何其他校正。
When there is an issue with an anti-lock brake system (ABS), there is typically either a red or yellow警告灯在仪表盘上，提醒驾驶员系统内存在问题。有几个问题导致警告灯亮起。如果传感器变坏，则控制单元或其他几种可能性存在问题，这些警告灯会亮起。
现代车辆采用了几个安全功能。为了保护反锁制动系统，就我们而言，它采用了保险丝和继电器在出现电气问题时保护接线和控制单元。本文的目的是涵盖如何更换安装在融合和继电器盒中的反锁制动保险丝或继电器。本文将涵盖一般替代品，而不是任何一个模型。
- 警告：请注意，制动液在任何涂漆/成品表面上都高度苛性，并且在彼此接触时会损坏这些表面。制动液是在大多数标准类型的制动液中可溶的水，用水中和。如果发生溢出物，请迅速用水冲洗受影响的区域，确保不要污染仍在系统中的制动液。
第1部分：1：更换防锁制动保险丝或继电器
需要的材料
Step 1: Locate the underhood fuse/relay box。打开引擎盖并找到保险丝/继电器盒。
Manufacturers typically label the box with the word “Fuse” or “Relay” on the lid, but not all will.
步骤2：删除弱点保险丝/中继盒盖。保险丝/继电器盒的盖子通常用手移除。
但是，有时需要一个小螺丝刀来轻轻撬起固定选项卡以释放它们。
步骤3：确定要更换的防锁制动保险丝或继电器。Identify the anti-lock brake fuse or relay that needs to be replaced.
大多数制造商都在“底部保险丝/中继盒”的盖子上提供了一个图表，该图显示了位于盒子内部的每个保险丝和继电器的位置和功能。
Step 4: Remove the correct anti-lock fuse or relay that needs to be replaced。卸下需要更换的防锁制动保险丝或继电器。
This is typically done by pinching them between your fingers and pulling them up and out or by using the fuse removal tool supplied by some manufacturers. You may need to either wiggle them back and forth while pulling on them or use a pair of needle nose pliers (optional relay puller pliers for a relay) to pull them out.
- Note: You can also use a small screwdriver to gently pry the fuse or relay from its position, as long as you are very careful not to make contact with the metal terminals on them. This can cause a short and lead to additional issues.
步骤5：匹配替换抗锁制动保险丝或继电器与替换。Visually compare the replacement anti-lock brake fuse or relay to the one being removed.
Be sure it has the same basic dimensions, the same amperage rating, and that the terminals are in the same number and orientation.
Step 6: Insert replacement anti-lock brake fuse or relay。将替换抗锁制动保险丝或继电器与旧的凹槽排成一列。
Gently set it in place and push down until it stops. The base should be flush with the fuse box deck and be approximately the same height as the fuses or relays around it.
步骤7：重新安装较低的保险丝/中继盒盖。Place the underhood fuse/relay box cover back onto the fuse/relay box and push down on it until it engages the retaining tabs.
当它参与时，应该有可听到的单击或毡咔嗒声。
步骤8：验证安装。打开点火开关。
验证仪表板上的任何警告灯现已关闭。系统可能需要一两分钟才能检查自身并关闭灯。
步骤9：测试车辆。Once all warning lights are off, close the hood and test drive the vehicle.
请注意仪表板，以了解可能重新出现的任何警告灯，并表明需要进一步的服务。
The anti-lock brake system is one of the most important systems in the modern vehicle. Most other systems in a vehicle can operate when they are at a less than optimal state with little noticeable difference or risk to safety. The anti-lock brake system needs to be operating properly for the safety of the driver, the passengers, and all others around them. If, at any point, you feel you could use a hand withreplacing an anti-lock brake fuse or relay，让您的一位您的经过认证的技万博体育入口术人员进行替换。
