![]() This can cause a short and lead to additional issues. 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.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. 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. Remove the anti-lock brake fuse or relay that needs to be replaced. Step 4: Remove the correct anti-lock fuse or relay that needs to be replaced. Most manufacturers provide a diagram on the lid of the underhood fuse/relay box that shows the location and function of each fuse and relay located inside the box. Identify the anti-lock brake fuse or relay that needs to be replaced. Step 3: Identify the anti-lock brake fuse or relay to be replaced. Sometimes, however, a small screwdriver is needed to gently pry the retaining tabs back to release them. The lid of the fuse/relay box is usually removed by hand. Step 2: Remove the underhood fuse/relay box cover. Manufacturers typically label the box with the word “Fuse” or “Relay” on the lid, but not all will. Open the hood and locate the fuse/relay box. Step 1: Locate the underhood fuse/relay box. Part 1 of 1: Replacing an anti-lock brake fuse or relay If a spill occurs, quickly rinse the affected area with water, being sure not to contaminate the brake fluid that is still in the system. Brake fluid is water soluble on most standard types of brake fluid is neutralized with water. Warning: Be aware that brake fluid is highly caustic on any painted/finished surface and can damage these surfaces when they come in contact with each other.This article will cover the general replacement and not any one model in particular. The purpose of this article is to cover how to replace the anti-lock brake fuse or relay mounted in the underhood fuse and relay box. To protect the anti-lock brake system, in our case, it employs fuses and relays to protect the wiring and control units when there is an electrical issue. ![]() The modern vehicle employs several safety features. If a sensor goes bad, there is a problem with a control unit, or several other possibilities, these warning lights come on. There are several problems that cause the warning light to come on. When there is an issue with an anti-lock brake system (ABS), there is typically either a red or yellow warning light on the instrument cluster to alert the driver that there is a problem within the system. The anti-lock system is designed to detect wheel lock up, release just enough pressure to allow the wheel to turn again, and still keep as much pressure in the braking system as possible without the driver having to make any additional corrections manually. The system intuitively, through a combination of sensors, electric servos/motors, and control units, senses wheel lock up and makes corrections in brake pressure in a fraction of a second. An anti-lock braking system is especially useful during very hard braking events to avoid an accident, when roadways are wet from rain, they are snow covered, the roadways are icy, or on loose driving surfaces such as dirt or gravel. 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. It works in such a way that there is no special input necessary by the driver to achieve maximum braking potential. The anti-lock brake system is a modern safety feature that greatly increases the effectiveness of the braking system, especially in adverse conditions. Most modern vehicles are equipped with an anti-lock braking system (ABS). ![]()
