As a car owner having an effective and operational ant-braking system is crucial. But first, do you know how to test abs module? If don’t, this complete instruction will take into detail on how to fast and effectively test this important car anti-braking system.
As drivers, we drive through different road terrains that come with diverse issues. Also, we are accustomed to driving in different weather conditions, and all these conditions can affect the quality and functionality of the ABS.
A clear sign that your car has a faulty ABS is the presence of a red warning right that appears on the board. If you see the red light, it’s either the ABS sensor or other component that is damaged, and replacing the damaged area is crucial.
If you are driving with a damaged ABS, it becomes hard to control a car, and this can lead to the occurrence of accidents. As such, it’s important to test the ABS module to check for damages. Let’s look at the insights and steps of testing the ABS module.
What is ABS Control Mode?
A car ABS is a braking control mechanism that guarantees safety when driving in rogue weather conditions and rough road terrains. ABS helps to prevent car wheels from locking, especially when driving.
Used by the most skilled drivers, this system has been incorporated by sporting ventures to allow drivers to make better maneuvers.
First, it was used by the aircraft industry, and with time, ABS technology has been conveniently incorporated into the car and motorbikes industries. For better control and braking, ABS incorporation is vital.
Importantly, this technology has been attributed to reducing the occurrence of accidents by almost 20%.
Types of ABS Control Mode
ABS control systems come in three basic forms; the four-channel, three-channel, and one channel system. Let’s take a closer look at these three types of anti-lock braking systems.
The Four-channel ABS
Among other ABS systems, this is the best option. A good aspect concerning this channel is remarkable skidding via pulsing the concerned wheel or wheels.
The Three-channel ABS
The three-channel ABS is made of front and back ABS sensors. On the axle housing, the back sensor attaches itself for effective control of both back wheels.
One Channel ABS
A back ABS that has one sensor located at the back axle housing. Mostly, you will find this ABS in trucks that have back ABS systems.
Specialties of ABS Control Mode
When driving, the wheels of a vehicle can get locked once the brakes have been fully applied. Locking of wheels leads to skidding and inability to control the car.
By functionality, the ABS is tasked with preventing the car wheel from locking and thus stabilizing the overall braking process. Traction control is important when driving, and the ABS helps to harness this mechanism.
Importantly, installation of ABS leads to increased traction control, ensuring each car wheel has robust traction while on the road. In rainy and snowy weather conditions, it becomes tricky to control the wheels of a car.
In these rogue weather conditions, ABS has been attributed for saving human life as drivers have better control of their cars.
Installation of this vital braking technology is crucial for better control of the car and, most importantly, helps save a life in incidences of accidents.
How to Test ABS Module
Skidding and loss of traction are major causes of car accidents. Installation of the ABS helps to reduce the occurrence of accidents by almost 20%. In some instances, the ABS can get damaged, and wheels lose traction leading to the emergence of a warning light.
Probably it could be damage on one of the wheel sensors. As such, it becomes crucial to test the ABS module to determine the problem. To do so, you will have to follow these steps, and here is what we ought to do.
Step 1: Make Preparations
Start by parking your car on a level ground location with all wheels having the same gradient level. Ensure you have a jack since we may need to lift the car and replace a damaged ABS sensor.
If there is a damaged sensor, you will have to remove the wheel, and thus it’s crucial to arm yourself with a bottle jack. Also, when removing the ABS sensor, we will need to be prepared with the right tools since the caliper and pads will need to be removed.
An important accessory needed in this process is the code reader. ABS code readers come in different forms, and it’s crucial to ensuring to go for one that complements well with your car make.
Importantly, in case of seeing flashes of the warning light or a completely lit one, it means the ABS module or sensors are damaged. On the cardboard, there are diverse locations where this warning red light can be situated.
So, check carefully to locate the problem, and the emergence of this red light means there is a problem with the ABS.
Step 2: Testing the ABS Fuse
A fuse is a vital accessory every electrical appliance must-have. They protect machines from power damage in case the current surpasses the stipulated voltage level.
Without this important electrical accessory, machines would fail frequently. If you find the fuse damaged, get a replacement and if it fails again, probably there could be a short in the ABS.
A short fuse can be located at the ABS computing machine or near the pump motor. The system fuse is located in the fuse panel.
Step 3: Testing System Wheel Sensor
Wheel sensor testing is an important test to check for any flaws around the wheel area. Through the ABS computer, the wheel sensor checks for the rotation movement of your car wheels.
Wheel sensors usually work hand in hand with the wheel stator. Mechanical and environmental conditions affect the overall rotation of car wheels.
From engine vibrations, debris to rogue weather conditions, a car ABS sensor gets affected by different conditions and exposures. A short is mostly prevalent under these conditions.
That’s why it’s important to have a voltmeter tool for testing every wheel sensor. A short in the wheel sensor means that you will need to remove the car tires by jacking up.
Step 4: Conducting System Computer Test
A car engine block houses the ABS module computer. First, turn off the car engine and check if the ABS computer is running. If so, you will hear a humming sound and it’s an indication of blown-out valve coils.
If there are damages, there will be required to remove and replace the blown-out valve coils. When replacing these accessories, ensure to go for quality ones and if need be, buy directly from your manufacturer dealer.
Step 5: Conduct Stator Ring Scan
You have now checked almost every part that usually is prone to damage in the ABS module. Sometimes you may have a damaged ABS and fail to see the red warning light.
Stator rings found in the ABS are prone to damage and mostly don’t get noticed since the red warning light doesn’t pop. Dislodging and damages are some issues that affect stator rings.
Missing teeth may cause one of the car wheels to rotate slower than the others leading to full operation of the ABS. As such, it’s important to check for damaged stator rings to ensure everything works to optimal levels.
Since there are different makes and models of cars, the stator ring can be located in different places. As such, scan to locate where it’s situated in your car. In case it’s damaged, replace it with durable and quality stator rings.
Testing the ABS module is vital to ensure the control your car better, especially when moving in rough road terrains. If there are lacks of the expertise to handle this, consult a professional mechanic for help.
ABS module is a fragile car accessory and testing it without expertise can cause more flaws. Also, when making replacements, go for original and quality replacement accessories.
Before embarking to test the ABS module, it’s vital to be armed with the right tools. All tools required to complete the testing are available in the market. Here are some notable tools used when testing the ABS module.
If the ABS sensors are damaged, will need to remove the affected car wheels. A jack will make it possible to lift the car and thus have it easy to remove car wheels and consequently replace the damaged ABS components.
Checks the rotational movement of car wheels by being connected to the wheel sensor.
A Code Reader
A code reader helps interpret codes about the ABS tool damage.
Symptoms of a Bad ABS Speed Sensor
Modern cars have innovated the braking system by coming up with the anti-lock brake system. In a car, there could be up to four ABS sensors set on each wheel.
They work by collecting vital data to determine when it’s appropriate to apply brakes while maintaining control.
Like all automotive accessories, ABS sensors get damaged and require to be replaced. Here are some common symptoms of a damaged ABS sensor.
ABS Warning Light Pops
A common symptom of a flawed ABS is the sign of a warning light. A car ABS warning light illuminates at night, showing there is a problem with the ABS.
Also, it can mean there is an issue with the control system. In case you see this light, visit a professional mechanic to service your most treasured asset.
A Car Braking Distance Increases Abruptly
In case of emergency braking, the ABS module should work in a manner that the car stops abruptly and in a smooth manner. Also, there should be no instances of skidding when emergency brakes are applied.
Automotive experts encourage drivers to continue harnessing more driving skills to avoid incidences of applying emergency brakes. If your car is taking longer to stop when brakes are applied, certainly there is a problem with the Abs.
Or if the car skids and your start experiencing loss of traction, then it could be a sign of a problematic ABS. Since this anti-braking system is made of a sensor and module, then one of these components might have been flawed.
Impaired Control On Rough Weather Conditions
If you are a professional driver, under different weather conditions, it’s possible to detect changes when braking. A car being driven under rainy conditions behaves differently from one being driven under dry weather conditions.
While driving in wet weather conditions and notice excess slipping tires in a brief time when taking off or stopping, then the ABS is flawed. Loss of car control under extreme weather conditions could mean either the sensors or module is damaged.
In case, your car ABS light pops in, there could be a problem with its sensors. Ensure the visiting a professional mechanic for repairs. Mostly, repairs are simple to make, and if the problems are severe, the sensor component should be replaced.
Without a properly functioning ABS, it is cumbersome to control and maneuver cars. From preventing cars from overturning to making the right braking distance, the benefits of this important car system are immense.
Although this technology has been incorporated by the sporting industry, there is no reason as a car enthusiast shouldn’t try it.
Follow all the above-mentioned steps and insights to better test the ABS and return it to its former self. In case you come across any damaged component, replace it with an original replacement part.
Also, if you are not a pro in testing the system, hire a professional dealer to conduct the test for you. As a driver, it’s always robust to be devised with the latest modern car technology for better control of any automotive machine.
Prevent accidents that occur due to brake flaws by testing the ABS once in a while.
