How To Reset ABS Light Without Scan Tool: Answered!

An ABS light on your dashboard can be worrying and may lead to costly repairs. However, it may only sometimes be a major issue, as it can be caused by something as simple as low brake fluid. There are so many ways to detect it, that how to reset ABS light without scan tool.

The process of resetting the ABS light without a scan tool can vary depending on the make and model of your car. Depending on the vehicle, it may involve the use of an OBD port or ABS diagnostic port, disconnecting the battery, or performing certain steps on the brakes or gas pedals.

So, read further down in this article to know how to reset the ABS light without a scan tool.

What Is ABS System & How Does It Work?

The ABS (Anti-lock Braking System) is a safety feature found in most modern vehicles. It helps the driver maintain steering control and stability while braking. When braking hard or on slippery surfaces, prevent the wheels from locking up.

ABS monitors the wheel speed using sensors on each wheel. When the system detects that one or more wheels are about to lock up, it pulses the brakes on and off rapidly to prevent the wheel from skidding. This is done automatically, and the driver may feel a pulsing sensation in the brake pedal when the ABS system is activated.

It uses a series of valves and sensors to control the brake pressure going to each wheel individually. When the driver applies the brakes, the system uses the sensors to detect if any wheels are about to lock up. If it detects a wheel is about to lock up, it reduces the brake pressure on that wheel, which allows it to continue rotating. This helps to maintain steering control and stability while braking.

Moreover, ABS can work with other safety features like Traction Control System (TCS) and Electronic Stability Control (ESC) to improve the vehicle’s overall safety.

What Causes The ABS Light To Come On? How To Fix It?

The ABS warning light could be on for several reasons, and before you try to turn it off, you should check the system and address any problems you find. Otherwise, the ABS warning light would return soon after the reset, and driving with a defective ABS is dangerous.

Moreover, turning off the traction control and the anti-lock brake systems is common practice when the ABS warning light comes on. Both of those things have a major bearing on security. So, here are a few potential triggers for the red alert.

Low Brake Fluid

Moreover, driving with insufficient brake fluid might cause permanent damage to the ABS’s internal components, rendering the system useless. When the ABS control module detects low fluid, it immediately activates the warning indicator and turns off the system.

Typically, the automobile will stop working after being driven for 10–15 miles with the brake fluid at a regular level.

Otherwise, the warning light will need to be reset, and if it comes on again soon after, there is likely another problem.

A faulty Speed Sensor

If your vehicle’s speed sensor malfunctions, the traction control warning light will also likely come on. Scan the car for error codes first, then replace the broken component before resetting the ABS light.

On average, that will cost you roughly $100, with most of that going toward the labor expense. Also, the actual speed sensor may cost as little as $20. Check out the instructions below to see if you can replace it and save some cash.

Step-by-Step Guide:

1. To begin, take the negative cable off the battery.
2. Then, jack up the automobile and place a jack stand under the wheel with the broken speed sensor.
3. You’ll find the speed sensor attached to a cable just behind the wheel’s hub.
4. One bolt typically secures the speed sensor; dip it in a rust remover to prevent it from breaking.
5. You must take off your wheel’s speed monitor to get to the connector and search along the cable. It could be hidden under a plastic shield.
6. Pull the plug and replace the sensor if the speed is inaccurate.

Faulty ABS Module

In addition to the warning light, ABS can make the brake pedal stiffer or require repeated presses to work. Sometimes, the speedometer stops operating altogether.

Repairing an ABS module is a costly endeavor for any vehicle owner. A new module costs about $800 for a Ford F-150 and about $1,400 for a Honda Civic. When compared to the module’s price, the average labor cost is between $50 and $100.

Furthermore, when upgrading the module, you must bleed the system. It is a complex process; even with a cheap labor cost, it is advisable to have a professional do it.

Low Battery Voltage

Multiple sensors are necessary for the operation of the ABS. Any power supply interruption will turn off the system and illuminate an ABS warning light. So, if you’re worried this could happen, quickly checking with a multimeter will reveal the truth.

Maintenance issue

Because of its vital role in protecting the lives of motorists, passengers, and pedestrians, the anti-lock braking system (ABS) is frequently the target of thieves. Removing the wheel speed sensor while changing components like brake pads or tires is standard practice. Especially in modern cars, that’s often enough to turn on a warning light.

Also, it must be clarified if other maintenance, like bleeding the brakes, replacing the brake pads, or changing the battery, can affect the ABS warning light. Furthermore, If you fixed something and then the warning sign came on, attempt to turn it off and on again.

How Do You Turn Off The ABS Light?

Now that you’ve repaired the faulty ABS parts or performed the necessary maintenance, you should reset the warning light. Although the instructions below are all prepared for a specific model, the same general ideas should apply to manuals for the same manufacturer and generation.

However, you won’t find these instructions in a workshop manual. Therefore they don’t apply to every vehicle. The ABS warning light is typically turned off after some time, even if a problem occurs.

Turning it off using a scan tool is more straightforward, but the following instructions will be helpful if that’s not an option. Assuming your vehicle is older and has an OBD1 port, removing the power source for a few minutes is the last resort.

How Can A Low Battery Cause ABS Light To Come On?

Because the ABS system depends on the vehicle’s electrical system for power, a low battery could turn on the ABS light. A weak or dying battery may not be able to provide enough power to the ABS.

& causes the ABS light to illuminate as a warning that the system is malfunctioning. Additionally, if the battery is low, it may not provide enough power to properly start the car, which may also cause the ABS light to come on.

However, it is worth mentioning that a low battery alone might not be the only problem. And there could be other issues with the car’s electrical system or the ABS itself, causing the light to come on.

If The ABS System is On, The Car Won’t Start?

A safety feature in a car called the ABS (Anti-lock Braking System) keeps the wheels from locking up when the brakes are applied heavily. When the ABS system is on and the car won’t start, it may indicate a problem with the ABS system or a related component that is preventing the car from starting.

Further, some common causes for this issue may include a faulty ABS control module, a problem with the brake system, or an issue with the car’s electrical system.

In order to diagnose and fix the problem, it may be necessary to take the car to a mechanic or dealer for further examination.

How To Maintain ABS System To Work Properly?

There are several steps you can take to maintain the ABS system in your Ford Focus or Ford Fiesta:

• Check brake fluid levels every day: Make sure the brake fluid level is at the proper level and add more if necessary. Low brake fluid can affect the ABS system’s performance.
