Why Is My ABS And Traction Control Light On? What Should You Do?

today ‘s modern cars have been equipped with an anti-lock brake organization, or ABS for curtly. This feature has proven to be a all-important piece of base hit equipment in cars by helping reduce the brake distance and provide add traction in low-grip situations .
Because the ABS and traction operate systems are one module and use the same sensors, if one fails, the early will likely cease angstrom well .
This article will help you understand what the ABS system does, how it operates, what may cause it to fail, a well as answer a host of early ABS relate questions .

What is an ABS system and how does it operate ?

If your wheels lock-up under unvoiced brake conditions, your stopping distance is greatly increased. The ABS system takes notice of that and releases the brakes in a sort of “ pulsing ” fashion to decrease the overall brake distance.

Comparing ABS and non-ABS car

How does the grip control system work ?

alternatively, if accelerating in slippery conditions, chances are the vehicle will break grip with the road. In the event of that happen, the traction restraint system kicks in by reducing the locomotive ‘s might to help the driver recover grip .

coarse ABS/Traction Control Light Faults

Have no fear, the cable car will however run and function absolutely fine, but greater caution should be taken while driving. Let ’ s have a attend at some of the most common faults associated with the ABS/Traction Control light being on .

defective Wheel Spin Sensor

Wheelspin sensors measure the rate at which the roulette wheel spins which is then relayed to the ABS/Traction Control faculty. If one rack is spinning faster than any of the rest, the car will then cut baron to the engine until grip is regained .
A bad detector will probably disable the system and the driver will be left up to their own to try and regain grip. common indications of a defective wheel travel rapidly detector are excessive wheel spin when taking off from a stand .

bad Steering Angle Sensor

As you might have guessed, the steering slant detector is creditworthy for measuring the fish of the steering bicycle. Another job the detector has is to track the speed at which the wheel is turned .
For the traction control system to work correctly, the vehicle must know where the driver is intending to go. If this detector fails, the car effectively is left without traction control, but be careful as this return might besides be disguised as a bad clock spring .

Faulty ABS/Traction Control Module

In rare cases, the module controlling the ABS/Traction control may fail, leaving you, the driver, without any traction control or anti-lock brake aids. While this might sound extreme point, it is not sol bad if the road conditions are dry .
As you might have guessed, the ABS/Traction Control module takes the incoming signals from the sensors and decides when to intervene. Think of it as a second copulate of eyes that is ready to help out at any moment .

System Malfunction

sometimes, one or several of the sensors get overflow with then much information they will basically freeze up. This will trigger the warn light on your dash and the ABS/Traction Control features will no longer work .

Poor connection

This issue is encountered quite much, many times after having work done around the wheels. It ’ s good to keep in take care that this is not always the encase.

If no recent bicycle work has been performed, it may be possible that the connections have merely worked themselves loosen over the years. In worst-case scenarios, the wires leading to the sensors can get severed due to excessive friction .

Repairing Common Faults

Wheel Speed Sensor

A wheelspin detector can become easily damaged due to them being exposed to the elements over the years. normally, they are located on the bracken forum of the vehicle and can be easily replaced .
To replace the detector, you must first locate it and the easiest way to do that is by removing the rack. After it is located, merely disconnect the wiring going to it and replace it with a newfangled one .

Steering Angle Sensor

The localization of a steering angle detector varies on each vehicle. It can be located behind the steering steering wheel, close to the steering box, or near the wheels, just like the wheel speed detector .
Depending on where it is located will determine the difficulty of replacing the detector. A simpleton Google search will tell you precisely where it on your car. Replacing it can be a simple as unplugging the old one and plugging a newly one in. It is crucial to know that sometimes the detector may good need recalibration .

Faulty ABS/Traction Control module

car-disc-brakecar-disc-brakeCar Disc Brake On most vehicles, the ABS/Traction Control module is located under the hood next to the brake fluid reservoir. It is comfortable to spot thanks to its large, square size and respective hard brake lines that lead to it .
Replacing the module itself should be a end recourse, as it can be quite unmanageable and expensive to replace. Be sure you have the proper tools and cognition before attempting this job. If the new faculty matches up to the erstwhile one, simply take off all connections from the previous one and install the new unit in place. once done, a brake shed blood operation must be performed to ensure there are no air bubbles in the system .

Improper connection

much, the wires leading into a detector may have come unaffixed, frankincense not making proper contact with the detector. This consequence can be resolved by making sure the connection is set securely in station .
To save you some time, scanning the car for faults with an OBD2 code lector such as this one is recommended as this will point you in the right direction .
While most automotive manufacturers use specific defect codes for their vehicles, they are sometimes interchangeable between most models. For exercise, codes ranging between C0031-C003E base that one of the speed sensors is malfunctioning on a Ford/Lincoln .
similarly, a wheel amphetamine detector on most Toyota models will be P0500.


Having your grip Control/ABS light turn on can be the cause of several problems, some requiring little good a simpleton resume, while others can take up a draw of time and money .
The best direction to figure out why the admonition light has been turned on in the beginning identify is to scan the vehicle for fault codes. After all, no one wants to replace a part that isn ’ deoxythymidine monophosphate break in .
We hope that this article helped shed some light on why the ABS/Traction Control ignite is on in your car and be certain to check out our early articles to help you with our early car-related issues !
