How much does it cost to replace anti-lock fuses or relay?

You can expect an average cost of $100-$200 for an anti-lock fuse or relay replacement. Prices can vary depending on factors like your mechanic and your vehicle.

How long does it take to replace anti-lock control fuses or relays? It typically takes around 1 hour for a professional mechanic to completely replace an anti-lock control fuse or a relay. Your mechanic will conduct an initial inspection to troubleshoot the problem to ensure the replacement is necessary, followed by the replacement process.

How did we estimate these prices?
Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my anti-lock fuses or relay replacement and how much do those parts cost?

Depending on your vehicle, you may need specific parts to complete an anti-lock fuses or relay replacement. Your best option is to check your owner’s manual or ask an automotive mechanic for their professional opinion.

For most vehicles, you need the following parts to replace the fuses in your anti-lock braking system (ABS):

Replacement fuses: There are usually two fuses associated with the ABS, but you’ll need to check your owner’s manual for a fuse diagram to locate them. These fuses have an amperage rating—usually 10 amp for the first fuse and 30 amp for the second fuse— which you’ll need to precisely match. Anti-lock fuses generally cost between $10 to $20.

Fuse puller: A fuse puller is a small tool used for safely removing fuses from their fuse box slots. Needle-nose pliers are also useful for fuse pulling, but they could damage the fuses. Fuse pullers typically cost $30 to $40.

To replace the relay in your vehicle's ABS system, you generally need the following parts:

Replacement relay: The specific relay that controls your vehicle’s ABS system will usually be found in the relay box under the hood or in the fuse box inside the cabin. You can find specific details about your anti-lock relay in your vehicle's repair manual or by asking a mechanic for part details. Your replacement relay part will need to match the specifications of your original relay. Replacement relays may cost between $20 to $100 depending on the vehicle.

Socket/connector: You may need a socket or connector to connect the new relay to the vehicle's wiring harness. This is needed for some vehicle’s but unnecessary for others, so ensure you have the right socket or connector if needed. Sockets and connectors can cost $9 to $50 or more.

We recommend purchasing parts at local auto parts stores such as AutoZone, Advance Auto Parts, and NAPA Auto Parts, as well as online retailers like Amazon and RockAuto. We also recommend trusted brands like Bussmann, ACDelco, and Littelfuse for these components. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.

Pro tip: Take a look at your vehicle’s owner’s manual or connect with a mechanic before purchasing parts. This way, you’ll be sure you have the right parts to correctly replace your fuses and relay.

Should I buy oem or aftermarket parts?

You can use oem or aftermarket parts to replace your anti-lock fuses or relay, but oem parts are usually the best option since they’re designed specifically for your vehicle.

Aftermarket replacement parts may be cheaper, but oem parts typically last longer, are more compatible with the other vehicle components, and may come with warranties.

Where can I buy parts for my anti-lock fuses or relay?

You can buy anti-lock fuses or anti-lock relay parts at an auto parts shop such as AutoZone, Advance Auto Parts and NAPA Auto Parts, a dealership mechanic shop, or a general mechanic’s repair shop. Parts like anti-lock fuses and anti-lock relays are also usually available online from storefronts like RockAuto and Autozone.

How will a mechanic replace my anti-lock control relay?

It doesn’t take long to replace an anti-lock fuse or relay, but the job requires a comprehensive understanding of the vehicle’s electrical components. If your car is showing signs of a bad anti-lock fuse or relay, your mechanic will go through the following steps to replace them:

Inspection: Your mechanic may take your car for a test drive to test the ABS system. They’ll look for signs of skidding, wheel locking, or your ABS light on your dashboard.

Preparation: The vehicle will need to be in park on a flat surface, usually with wheel locks to keep the rear wheels in place. Your mechanic will need to disconnect your car battery to access the fuses or relay, so they may connect a nine or 12-volt battery to the interior of your car to keep the computer running.

Locating and removal: The anti-lock fuse and relay will be located in the fuse box in the engine bay. Your mechanic will remove the fuse box cover and unscrew any additional components to find the ABS fuse or relay. The faulty fuse or relay will then be removed.

Installation: Your mechanic will install the new anti-lock fuses or relay into the fuse box and re-install any components that were taken out during the process. The fuse box cover will also be placed back, and your battery will be reconnected. In some cases, your mechanic may also replace the coolant in your vehicle.

Test: To verify that your anti-lock fuses or relay are working correctly, your mechanic will take the vehicle for another test drive. If the brake pedal pulsates, the wheels don’t lock, and there is no skidding present during hard braking, your new fuses or relay is working. Once the job is completed, any dashboard lights should be gone.

What happens if I don’t replace my anti-lock fuses or relay?

If you notice skidding, wheel locking, or your ABS dashboard light is on, you should get your anti-lock fuses and relay inspected by a certified mechanic. If you do not replace a faulty anti-lock fuse or relay, you could encounter the following problems:

ABS failure: If one or more of your anti-lock fuses blow or if your relay fails, the brake fluid pump will stop operating. Without brake fluid pressure from the pump, the ABS system will also stop working.

Skidding and wheel locking: If your anti-lock fuses or relay are not operating and your brake fluid pump and your ABS system fails, your wheels may lock up and skid when you try to brake. In some cases, you may have to apply a lot of downforce on the brake pedal to stop your vehicle.

What is an anti-lock fuse or relay?

Anti-lock fuses and an anti-lock relay are parts of your anti-lock braking system (ABS).

The ABS fuses and relay are integral parts of the system that allow power to reach the components. The relay is an electric switch that opens and closes, allowing power to reach the system. The fuses, on the other hand, are protective devices that ensure that the system does not receive too much power.

If either one of these components malfunctions, your ABS will most likely stop working. While you can drive your car without a functioning ABS, the system will be unable to protect you during harsh weather, potentially leading to unsafe driving conditions.

When should I replace the anti-lock fuses or relay on my car?

You may notice any of the following signs if your ABS fuses or relay are in need of replacing:

ABS light is on: If the ABS light or check engine light on your dashboard stays on after you start your car, something is likely wrong with your ABS system. Your ABS light could indicate a blown anti-lock fuse, a faulty control relay, a faulty anti-lock sensor, low brake fluid, or a worn out ABS pump.

Unresponsive brake pedal: If your brakes seem to be underperforming, it could be due to a faulty relay or blown fuse. For example, if you need to press down on the brake pedal several times to stop your vehicle, there’s probably something wrong with your anti-lock control relay. Air in the brake line or worn out brake pads could also cause your brake pedal to be unresponsive.

Locked wheels: If your wheels lock up when you apply pressure to the brake pedal, then your ABS system is not working correctly. Locking wheels are usually caused by a failing ABS relay.

How often should anti-lock fuses or relays be replaced?

Anti-lock fuses and relays don’t have specific lifespans, but they generally last 10,000 miles or more if the ABS system is properly maintained. Some vehicles may require replacements sooner than later, so it’s best to check your owner’s manual or consult with a mechanic or dealership.

Pro tip: Regularly inspect the electrical wiring around your engine compartment’s fuse box. If your wires and connectors are secure and free of corrosion, your fuses and relay are likely in good condition.

Can I replace my anti-lock fuses or relay myself?

Replacing an anti-lock fuse or relay is fairly straightforward, so you could replace these parts on your own. Keep in mind that process may be specific or include extra steps for your vehicle, so letting a certified mechanic replace your anti-lock fuses or relay may be the best option.

FAQs

How much does it cost to replace an ABS relay?

On average, it costs $100 to $200 to replace an ABS relay. Depending on your vehicle, an ABS relay replacement could cost more than the average price.

How do I know if my ABS fuse is blown?

The ABS warning light on your vehicle’s dashboard could signify a blown ABS fuse. If the light turns on and stays on after you start your car, it may be due to a blown ABS fuse or another issue with your anti-lock braking system.

Additionally, you may notice your wheels locking up or skidding if an ABS fuse is blown.

How long does it take to replace a relay?

It generally takes an hour to replace an anti-lock relay. The amount of time required to replace your anti-lock relay will depend on your vehicle’s make and model.

Can you drive without an ABS fuse?

Yes, you can technically drive without an ABS fuse, but your anti-lock braking system will not work if an ABS fuse is unplugged. Without your ABS system engaged, your vehicle could slide or your wheels may lock up if you brake hard.
