The Ultimate ABS System Buying Guide

A Buying Guide For ABS System Parts

Brakes are vital for the safety of the vehicle occupants and the passengers on the road. The braking systems have developed over time to new technologies like Anti-Lock Braking Systems (ABS) that are a standard feature in many cars today. In the old times, the drivers used to pump the brake pedal to avoid the wheels from locking and skidding. The anti-lock brake system does the same by modulating the pressure using sensors and a control unit so the vehicle can be brought to a safe stop. This ABS system comprises several parts like modules, sensors, etc. that people are unaware of. This comprehensive ABS parts buying guide will help you understand the working of the ABS system of the vehicle so you can choose the correct part for your vehicle.

What Is An ABS Module And Why Do I Need It?

The ABS module is the central unit of the anti-lock braking system. It is a microprocessor that processes information from the hydraulic brake system and the wheel-speed sensors to regulate the braking pressure and prevent the wheel from locking and skidding. 

The ABS control module is located in the engine compartment or under the hood. In some vehicles, it can be located in the frame rail near the driver. The ABS module works in conjunction with the sensors and hydraulic valves to prevent the wheels from locking up. It also performs diagnostic checks on the vehicle's ABS and indicates any possible faults with the system.

What Are The Factors I Should Consider When Looking For An ABS Module?

It is very important to choose the correct ABS module to ensure maximum safety and performance. If you want to get the best value for the money you spend, you should consider the following points while looking for a replacement ABS module for your vehicle.

1. Compatibility

In some vehicles, the ABS module is part of the traction control system. Therefore, it becomes very important to ensure that the replacement you are going to purchase is compatible with your vehicle's specifications. PartsAvatar makes this simple for you, as you can select your vehicle's make, year, and model to find the perfect fitment ABS module for your vehicle.

2. New vs Remanufactured ABS Module

ABS modules are available in two options: Remanufactured and brand new. Remanufactured ABS modules are built by replacing the missing, worn-out, or non-functioning components of the module and are computer tested for consistent performance. New ABS modules are expensive compared to remanufactured ones, but they give you that peace of mind that comes with installing a brand-new part in your vehicle. Both are decent options to choose from but if the budget allows you should always go for a new ABS Module. Remanufactured modules save you a lot of money, last equally long as the new ones, and are even backed by warranties from reputed brands.

What Are The Symptoms That My ABS Module Is Failing?

1. Brakes Locking Up

The ABS system is designed to prevent the wheels from locking up during heavy braking. However, the ABS module can malfunction, causing the brakes to lock up. Usually, when the ABS module fails, this problem goes unnoticed until you slam on the brakes. A failing ABS module can even cause the brakes to lock under normal driving conditions.


2. ABS Warning Light Is On

Some vehicles are equipped with an ABS warning light that indicates any problem with the ABS module. The warning light is usually amber colored and can also illuminate if there is a problem with the ABS sensors. Other vehicles that do not have an ABS warning light may use the check engine light instead. 

3. Unresponsive Brake Pedal

In some vehicles, the brake pedal can become unresponsive when the ABS module fails. Often the symptoms start gradually when the brake pedal has to be pressed a couple of times to work. The problem can worsen with time when the pedal becomes unresponsive. 

4. Increased Brake Pedal Effort

The pedal should require very little effort for the braking system to function properly. If the brake pedal requires more effort or has to be pushed a lot to achieve the same braking force, then the ABS module might be at fault.

How Much Will It Cost Me For A New ABS Module?

The ABS module can cost somewhere between $300 to $1400 depending on the vehicle's year, make and model. It is recommended to get the ABS module replaced by a professional mechanic, and it can further cost you labor charges. 

What Is An ABS Sensor And Why Do I Need It?

The anti-lock braking system uses an ABS sensor to monitor the wheel speed and send the information to the ABS module. The ABS sensor, also called the wheel speed sensor, consists of a toothed ring and a magnet in a coil. When the ring comes in contact with the magnet, a voltage is generated, which is then transferred as a signal to the ABS module. This is how the sensors send the signal and the ABS module keeps track of the rotational speed of the wheel. 

What Type Of ABS Sensor Should I Choose?

Vehicles use two types of ABS sensors; active sensors and passive sensors. Passive sensors work without a power supply, whereas active sensors require a power source for functioning.

1. Passive ABS Sensors

Passive ABS sensors comprise an ABS ring that rotates with the wheel. This ring has teeth that on rotation create magnetic flux through a coil. This generates a voltage that changes with the wheel speed. The sensor creates an AC signal that changes frequency with the vehicle speed and sends it to the ABS module. Although they are simple in construction, passive ABS sensors are inaccurate compared to active sensors and cannot operate in reverse. They are used on older cars and have become obsolete today.


2. Active ABS Sensors

Active ABS sensors use an external power source and work in conjunction with a toothed or magnetic ABS ring. Active ABS sensors are further divided into Hall sensors and Magneto-resistive sensors. Hall sensors comprise a toothed ring on the wheel hub, rotor, or bearing, whereas the magneto-resistive type active sensor uses a magnetic encoder ring that changes resistance while passing the sensor as the wheel rotates.

Active sensors are very accurate and can detect speeds less than 0.06 mph. This makes them vital for traction control systems used in modern cars. As the technology has advanced, newer vehicles have started to incorporate active ABS sensors as they are safer and more reliable compared to passive ones.

What Factors Should I Consider Before Buying ABS Sensors?

The anti-lock braking system (ABS) sensor monitors the speed of the wheel and helps the ABS module to take over manual braking under conditions when there is a loss of traction. If the sensor fails, the ABS system can behave erratically and lead to accidents. A damaged sensor must be replaced immediately, and you should consider the following factors before purchasing one for your vehicle.


1. Location

Always check the location of the ABS sensor, whether it is for the front, rear, driver, or passenger side. Typically, the sensors are located in each wheel hub on a four-channel ABS system, and some rear-wheel-drive vehicles have sensors mounted in the differential.

2. Fit

While purchasing ABS sensors always ensure that they are engineered to match the exact OE specs. The ABS sensor should be compatible with the make, model, and year of your vehicle for the ABS system to work properly. PartsAvatar makes this easy for you as you can select the vehicle and purchase the perfect-fitment ABS sensor.

3. Specifications

ABS sensors come in different types, as some of them have a wiring harness with a pin or a blade. Some ABS sensors have a 2-prong connector or a couple of wires. All these details must be taken into consideration while purchasing an ABS sensor for your vehicle. Therefore, always consult your mechanic or the vehicle manual to find the exact replacement.
