Battery And ABS Light Comes On, What To Do Now?

The Battery system light indicates that the battery is not being charged. Alternator brushes or a transistor might be failing! Alternatively, you might lose your wiring. Low power might be causing the ABS indicator to illuminate, Low voltage is not good for control modules. Rather than that there must be several reasons your ABS and battery light indicate.

Consider the following scenario: You’re driving and your battery and ABS light comes on. What to do now? Pull aside as quickly as possible if the car is still drivable so you may safely examine beneath the hood to see if anything noticeable has popped off or become disconnected. It’s too late to fix whatever has come undone at this point, but you can still pull over and put the car in park before it becomes a bigger problem. It is definitely recommended that you have a specialist evaluate your vehicle as quickly as practicable. To know more read the below article

Why Does The Car Battery And ABS Light Comes On?

Anti-lock brakes are a complicated system of computers and sensors. When all of the components are performing in perfect unison, the outcome is a rapid, responsive system that improves brake control in all situations. The flashing lights in the gauge cluster are frequently the first sign of a problem in this system. When a malfunction is identified in most cars, just the ABS light illuminates. What if the ABS and BRAKE lights are both flashing on your automobile or truck? Here are several likely reasons and solutions for both flashing lights:

1. Bad Battery

The ABS and traction control lights may appear due to a low or weak battery. Despite the fact that it may have an influence on your vehicle’s overall performance.

It’s not a healthy sign if your vehicle’s ABS light comes on. This indication indicates that your car is experiencing certain problems and that you should thoroughly examine all systems. Consider the possibility that your battery is damaged or dead in some manner. The battery must always be charged then after.

2. Sensor Defect

Sensors in the ABS analyze the angular velocity of every wheel. A computer monitors the information across all four wheels including the placement of the brake pedal to ensure the automobile is steady and under command. The ABS warning light will blink if the computer detects any unusual signals or a loss of signal from one of the detectors.

3. Brake Fluid Is Low

The abs light on the dashboard indicates that the braking fluid has either departed the system due to a leak or evaporation or that the fluid level has fallen but the sensor has not detected it. If the brake fluid level lowers and the ABS light flashes on and off, the sensor is malfunctioning and must be replaced.

4. A Blown Fuse

An illuminated ABS Light is undoubtedly one of the first signs of a blown fuse or relay. When the computer detects a flaw in the system, the ABS Light will often glow. When a fuse blows or a relay fails, the computer will take up the sound and even turn on the Check Engine Light to warn the drivers.

How Do You Recognize And Deal With An Abs Or Brake Light Issue?

In an emergency, such as on icy or rainy roads, the ABS system works in conjunction with the braking system to preserve control. A rapidly pulsing brake pedal or minor vibrations are signs of problems. Perform the diagnostic steps below to discover the faults.

1. Try To Reset The Abs Light

Turn the key on and off in the ignition to see if the panel light comes on. This can sometimes remedy the problem by resetting the code in the system memory. This is how you can reset your ABS light without using a scanner.

If the problem persists, take the car to an auto shop for a scan to discover and correct the code.

2. Top Up Brake Fluid

Apply greater pressure to the ABS brake if the car will not stop. If the brake fluid level is low, check it and replenish it to the specified level. It also signifies that there is air in the hydraulic system, which may be resolved by bleeding the system.

If you hear a clunking noise when you apply the ABS brakes, replace any damaged or loose front-end parts.

3. Replace Blown Fuse

The anti-lock brake system, like most other systems or electrical components, will have its own fuse. Make sure the ABS fuse isn’t blown or burned before replacing pricey equipment or spending time troubleshooting. A quick inspection of the fuse box may save you a lot of time.

4. Perform ECU Diagnosis

Perform a series of general checks to ensure that power and ground are reaching the ECU. ABS functionality is dependent on the ECU being properly grounded and getting the appropriate operational power. Locate the ground and power circuits, then conduct voltage and continuity checks on the power and ground, respectively.


Frequently Asked Questions:

Here are some of the frequently asked questions about battery and abs light comes on:

Q: Is Driving A Car With An Abs Light On Safe?

Yes, it is secure. Even having the Abs light on, the automobile brakes will function normally under typical braking conditions. However, in severe braking scenarios, the brakes will lock up, causing the wheels to slide. Your ABS system is crucial when your wheels lock up when you use heavy brakes on ice in the winter.

Q: What May Go Wrong With Abs?

ABS is seldom defective unless the ABD controller is faulty due to one or more sensors or poor sensor cabling. Corrosion, dirt, or metal shavings are the most typical causes of sensor contamination. Only when you stomp on the brakes and observe the wheels locking up while driving will you detect a problem.

Q: Will Removing The Battery Reset The Abs Light?

Is it possible to reset the ABS light by disconnecting the battery? Yes, if the car battery is detached for long enough, the Abs light will be reset.

Q: Is The Abs Light Caused By A Low Battery?

The Abs light may illuminate due to a low battery. The Abs light can also be illuminated if the brake light is not working or has burned out.


The ABS light is a safety feature that warns drivers when the Anti-lock Braking System is malfunctioning. If your automobile has been running for a long and you notice that the battery and abs light comes on, pull over or drive as swiftly as possible to a gas station or repair shop. Low battery voltage can be recognized by sensors in many components of your car, which is one of the most prevalent causes of ABS system failure. It’s possible that your car’s brakes aren’t working correctly due to a low battery or another issue with the brakes.

I recommend having your automobile inspected as soon as possible to ensure that this does not happen again and to avoid any future safety issues.
