How Does The Traction Control System Work on Vehicles?
A traction control system (TCS) is an invaluable safety feature in all modern cars, helping to prevent wheel slip during acceleration. It works by tracking the wheel’s rotational speed through wheel speed sensors.
With these sensors, the car’s electronic control unit (ECU) receives data to be read by it around the clock and can spot any wheel spin when specific conditions are not met.
Traction control system
When the TCS detects a spinning wheel, it triggers to regain traction. It does this in several ways:
Engine Power Reduction
This can be accomplished by modifying the throttle position sensor, advancing/retarding the spark timing or disabling fuel to particular cylinders. The power cut is delivered to the wheel that lost grip and allows it to get back on track.
Stopping Individual Wheels
TCS can use the callipers on a spinning wheel, sending power to wheels with more grip. This could help slow the car down and keep it moving in a forward fashion instead of sliding all over.
Works with ABS
The TCS frequently functions with the anti-lock brake system (ABS). ABS prevents wheel lock-up when braking and TCS prevents wheels from spinning during acceleration.
We have traction control watching over the shoulder of this system. TCS constantly monitors and adjusts how a vehicle’s dynamics are playing out, which means increased safety.
Especially in less-than-ideal conditions or environments such as wet roads, snow-covered streets, and loose gravel areas, to name just a few places where unlocked wheels can spell doom for you!!
Reasons for Traction Control Light On and Car Won’t Accelerate
Modern cars come standard with traction control, which bundles a slew of safety systems together to check wheel slip when accelerating.
It ensures the tires provide a proper grip on the road surface, especially in poor traction conditions during rain or when snowy and/or icy.
An intervention that can result from the traction control system determining a loss of grip is either engine output reduction or controlled braking to any specific wheel.
Here we have found major reasons for traction control light comes on and car won’t accelerate:
Faulty Wheel Speed Sensors
As the name implies, they are devices that detect and gather information about how quickly each wheel is spinning.
In the event of a failure, a wheel may be falsely identified as slipping by the traction control system (resulting in both an illuminated light and reduced acceleration).
ABS (Anti-lock Braking System) Problems
The ABS uses many of the same components as our traction control system. An ABS issue, like a failed module or sensors, can trip the traction control light.
A Failed Steering Angle Sensor
This sensor detects the angle and rate at which you turn your steering wheel. A malfunction will affect the operation of your traction control system.
Low Tire Pressure
Uneven tire pressure sensor can disrupt speed at the wheel, triggering the traction control light to come off.
Electric Problems
Damaged wiring or a faulty control module can also be the reason why the traction control light will illuminate.
How To Diagnose Traction Control Light is On and Your Car Won’t Accelerate
Check Error Codes
Cars are now equipped with an onboard diagnostics system (OBD-II). Error codes can tell you what caused the traction control light to illuminate in the OBD-II.
Inspect the Wheel Speed Sensors
Check the sensors and their wiring for damaged insulation or disconnection.
Tire Pressure
Make sure all your tires are at the correct pressure according to manufacturer specifications.
Check ABS
Visually check the operation of the ABS system and have it inspected by a professional
Consult a Mechanic
Finally, if you cannot figure out the problem and fix it by yourself seek professional help from a qualified mechanic. They can look at it and tell you right away what is causing your problems.
Why Should You Fix Traction Control Light And Car Won’t Accelerate
Not caring about your traction control light problems can create some very dangerous situations, both safety and performance-wise.
The traction control system (TCS) prevents the drive wheels from slipping by sending signals to the engine and brakes. The TCS light illuminates, which signifies that the system is having an issue and needs to be looked at quickly.
Safety Concerns
Traction control system works to maintain the traction and stability of your vehicle, particularly in adverse conditions such as wet or snowy roads. When the TCS malfunctions, it will make your car skid-prone and harder to handle.
If you ignore the warning light, your traction on slippery surfaces may be reduced, which could lead to an accident, for example.
Underlying Mechanical Issues
The traction control light may also be caused by problems with wheel speed sensors, ABS malfunction illumination on the dash display or a tire is low in air. Failure to heed these signals can ultimately destroy your car-parts, thus costing you more during repairs.
Performance Impacts
A properly functioning TCS can impact the way your car drives just as one that is not working does. Slower acceleration and handling can make it more difficult to drive, costing you time with little added value.
Taking care of it before your car breaks down helps the performance remain high and frictionless. Finally, the traction control light is one of those tale lights that warns you if there’s a serious problem with your car.
But if neglected, it can undoubtedly cause hazardous driving conditions, more expensive repairs and hamper vehicle performance. Treat traction control warning light with immediate attention to keep your car safe and reliable.
How To Prevent Traction Control Warning Light
Routine Servicing: Getting regular service on your vehicle can fix many problems that activate the traction control light.
Check Tires: Examine and check the tread depth of your tires, as well as their overall condition, including air pressure.
Dashboard Lights: Click here to learn about dashboard warning lights you should always heed. Dealing with early issues can prevent worse things from happening in the future.
FAQs On Traction Control Light On and Car Won’t Accelerate
Why Does My Traction Control Light Comes on?
In most vehicles, the traction control light comes on when there is a problem with that system, or it may just be indicating that it is actively being used to prevent wheel slip. These are caused by faulty wheel speed sensors, ABS issues such as low tire pressure, or electrical malfunctions. Like any automotive problem, the sooner you diagnose and repair it, the better chance you have of keeping your car safe and reliably on time.
Is It safe to drive with Traction Control Light on?
Although it is not ideal to drive with the traction control light on for a lengthy period of time, the light on is a sign of possible problems with the traction control system, which helps maintain vehicle stability and overall safety in slick conditions. The traction control system is indicated in the dashboard or LCD. If it is not on, then we are going to be able to lose our car!!
How To Reset The Traction Control Light?
If you cannot find the problem, you should simply try turning off your car and restarting it to see if that resets the system. In many cases, a simple reset will turn out not just for most check engine faults but even universal maintenance indicators! If the light stays on, use an OBD-II scanner to read and clear any error codes. But and this is a big problem you need to repair the root of what caused that light to remain on and not simply reset it.
What Makes The Traction Control System Fail?
There are a number of aspects that will cause the traction control system to not function properly. Some issues may be from wheel speed sensors, ABS problems, steering assist system issues, low tire pressure, or electrical problems within the Traction Control System. These problems can be avoided through regular maintenance and addressing warning lights as they appear.
Conclusion
Your traction control system is one of your car’s best safety features, but when the light flashes and you lose power to accelerate, things are not so safe anymore.
Understanding these common causes and taking the proper precautions can keep your vehicle safe on the road. Your vehicle needs regular maintenance, and if you aren’t sure what your car needs, first, check all the necessary parts that will prevent traction control from having issues.
If the problem persists, you can always consult an expert. Keep your vehicle in top-notch condition by driving safely and proactively maintaining its health to have a hassle-free drive.
