Will Pulling ABS Fuse Turn Off Light
Are you looking for the right way to turn off the ABS light? You are in the right place.
Yes, you can reset ABS light by pulling the ABS fuse. First, pull out the fuse. To reset the central computer, hold down the brake pedal for a few seconds to drain the electrical system. After reinserting the fuse, drive for 30 seconds to let the computer recalibrate. The end result? The ABS light is successfully disabled and your car is ready to roll!
Here I will explain to you step by step how I reset ABS light by the way I mentioned above.
What is ABS?
The term “ABS” stands for “anti-lock braking system. The ABS is in charge of ensuring your safety and maintaining control over it in the event of an emergency involving severe braking.
Types of ABS
There are five different types of anti-lock braking systems, based on the number of speed sensors and valves.
| Type of ABS | Details |
| Four channel-four sensors | Each wheel has its own sensor and valve. |
| Three channel-four sensors | Separate valves for front wheels. A single valve is for both rear wheels. |
| Three channel-three sensors | A valve and sensor in each front wheel. A valve and a sensor for each rear wheel |
| Two-channel, four-sensors | It uses a speed sensor at each wheel and one control valve for the front and rear wheels together. From the late 1980s until the mid-1990s, this system was often used on passenger automobiles. |
| One-channel, one-sensor | It has a single valve that manages both of the back wheels and a single speed sensor in the axle. This system functions in the same way as the three-channel system’s back end. Pickup vehicles, SUVs, and vans with rear-wheel ABS frequently have this system |
What is the Use of ABS?
By applying and releasing the brakes on each wheel independently, the ABS helps to maintain traction and control of the vehicle, especially in emergency braking scenarios. This system plays a significant role in improving driving safety by preventing accidents caused by skidding or loss of control during braking.
How Does the Anti-lock Braking System Function?
The speed sensors in your car detect the wheels’ braking when you suddenly apply the brakes. The Hydraulic Control Unit (HCU) receives a signal from the system when it detects that one or more wheels are about to lock up, causing the brake fluid pressure to be reduced on that wheel.
The brake pressure is modulated during this process. The Electronic Control Unit (ECU) is then informed by the HCU to control the brake fluid pressure. The HCU then receives instructions from the ECU to release and reapply the brakes.
Until the vehicle comes to a complete stop or the driver lets off the brake pedal, this process continues.
This short video will help you understand this much more.
What Parts Make Up an Antilock Braking System?
A fully operational ABS system is made up of a number of parts that all work together. This is what an automobile’s ABS consists of.
Speed sensors:
The speed sensors, which are positioned at each wheel of the vehicle, are in charge of keeping track of the rotational speed of the wheels.
Hydraulic control unit (HCU):
The ABS system’s primary control unit is the HCU. It is made up of valves and pumps that regulate the brake fluid’s pressure.
The electronic control unit (ECU):
This is the ABS system’s mental center. It analyzes the information from the speed sensors and transmits commands to the HCU to regulate the brake fluid’s pressure.
Brake lines:
The brake lines carry the brake fluid from the master cylinder to the brake calipers or drums.
Brake calipers or drums:
These components are responsible for applying the brake pads or shoes to the rotor or drum when the brakes are applied.
Brake pads or shoes:
They make contact with the rotor or drum to slow down or stop the vehicle.
What is Indicated by ABS Light?
The ABS (Anti-lock Braking System) light on a car’s dashboard serves as an indicator of any issues or malfunctions in the ABS system. When the light is illuminated, it indicates that the ABS system is not functioning correctly. This could lead to reduced braking performance and increased stopping distances.
A properly functioning ABS system helps prevent the wheels from locking up during sudden braking, improving vehicle control and reducing the risk of accidents.
How I Reset ABS light by Pulling the Fuse?
I started by locating the fuse box and the ABS fuse using the diagram on the ABS box cover.
Then I removed the ABS fuse.
I hold down the brake pedal for a few seconds, draining the electrical system of the car. It caused the main computer to reset.
My final step was to reconnect the ABS fuse.
After reconnecting the fuse, I continued to drive for 30 seconds so that my computer system could recalibrate. Done! ABS light has gone off.
If the fuse is blown, you should replace it. This short video will help you find the fuse and replace it.
Note: It’s important to use the correct replacement fuse with the same voltage, amperage rating, and type as the original one.
How to Check a Fuse by Using a Multimeter?
Here are the steps to check the ABS fuse.
- Set the multimeter to the ohms setting and select the 20K range.
- Check the multimeter leads to ensure that they are in the correct locations for measuring ohms.
- Touch the leads together to make sure that the multimeter is working correctly. The reading should be zero or close to zero.
- Take the fuse and make sure that you are not on a metal surface.
- Touch both sides of the fuse with the multimeter leads and check the reading. It should be zero close to zero.
- If the reading is close to zero, the fuse is good. If the reading is high, the fuse is bad and needs to be replaced.
How to identify a Blown Fuse without a Multimeter?
Most of the time, you can easily identify a blown fuse by its appearance.
Inspect the fuse for any signs of damage or melting. A blown fuse will have a broken filament or wire inside the glass or ceramic body of the fuse. The wire may be visibly burned or discolored, or the glass body may be dark or discolored.
FREQUENTLY ASKED QUESTIONS(FAQs):
What ABS type is best for a car?
Due to the fact that it only activates the affected wheel out of four in the event of unexpected braking, four-channel ABS is the most popular and efficient type of ABS. In four channel ABS, the vehicle is equipped with sensors on each of its four wheels.
What happens if I remove the ABS fuse permanently?
ABS system will be permanently disabled. You can drive with normal brakes.
What are the main benefits of ABS?
- Better vehicle control: ABS prevents the wheels from locking up during severe braking, which would otherwise cause the vehicle to slip or skid. This helps drivers keep control of their cars.
- A shorter stopping distance: ABS enables the driver to hit the brakes firmly without worrying about the wheels locking up. As a result, the stopping distance is reduced, which could aid in preventing accidents.
- Improved steering performance: ABS supports the driver in maintaining steering control during forceful braking, which is crucial in emergency situations.
- Increased safety: ABS can help prevent accidents and lessen their severity by enhancing vehicle control, reducing stopping distances, and improving steering ability.
- Enhanced driver confidence: When drivers are aware that their car has ABS, they may feel more in control and confident, which may result in safer driving habits.
Do ABS brakes affect mileage?
No, in general, ABS (anti-lock braking system) do not significantly affect the mileage of a vehicle. ABS is an electronic system that is designed to help the driver maintain control of the vehicle during hard braking by preventing the wheels from locking up.
Conclusion
I hope you got enough information to reset your ABS light. Note that the problem that caused the antilock braking system to disable should be corrected before trying to fix the light. Because if there were any problem with ABS, light will keep on.
