Your vehicle’s traction control system requires servicing when the “Traction Control Light” becomes illuminated and the accelerator remains deactivated.

By regulating the engine’s output or braking certain wheels, this device is intended to keep the wheels from spinning while accelerating. If this system is malfunctioning, it could compromise the safety and performance of your vehicle.

Difficult, isn’t it?

The purpose of this article is to explain the problem, identify its possible causes, and offer workable solutions. Let’s begin!


Solution #1 – Check Traction Control System

If your vehicle is hesitant to accelerate and the “Traction Control Light” comes on, it’s as if it’s trying to tell you, “Hold on, something’s up with my grip on the road.”

Here are some options for you:

First things first, check the speed sensors on each wheel. They keep a watch on the speed of each wheel, much like the eyes on your car.

These sensors are vulnerable to minor damage and occasional pranks played by the wires that link them. It might be a cut cable or a sensor that suffered a minor hit, so be sure to look closely for any visible damage.

Find any ice or debris and remove it. Anything that would obstruct these sensors could have been in your vehicle during a snowstorm or other severe weather event. You might be surprised at how much the issue disappears with a quick cleaning.


Solution #2 – Inspect ABS System

The Anti-lock Braking System (ABS) and traction control are like best friends who help each other out when driving. So, if one is acting up, the other might respond with a tantrum of its own. Here’s what to do:

Common ABS System Issues and Fixes

  • ABS Sensor Malfunction: If the ABS sensors that measure the wheels’ speeds stop working, the traction control system can receive erroneous data.
  • Problems with the Brake Fluid: If there is insufficient or contaminated brake fluid, it can damage the ABS hydraulic unit and make the system not work properly.
  • Problematic ABS Control Module: This module oversees the whole ABS system. If a module isn’t working properly, the traction control and anti-lock brake systems won’t work together as intended.

Look for obvious signs of contamination or damage on the ABS sensors. Inspect and repair sensors as required.

Then, check that the brake fluid levels are where they should be. Seek out indications of degeneration or contamination.

To find DTCs (diagnostic trouble codes) associated with the ABS, use an OBD-II scanner. Specific problems with the ABS module can be better understood with the help of these codes.


Solution #3 – Inspect Wheel Bearings

On that note, wheel bearings are essential for smooth, friction-free wheel rotation. Wear and damage can affect the traction control system, causing the illuminated light and poor acceleration.

Common Signs of Wheel Bearing Issues:

  • While driving, listen for growling or grinding. These noises often indicate worn wheel bearings.
  • Wheel bearing problems can cause excessive steering wheel or vehicle floor vibrations.
  • Check for uneven tire wear because damaged wheel bearings can affect wheel alignment.

For inspection, lift the car with a jack to raise the wheels. Move each wheel by hand next. Wheel-bearing issues may cause excessive wobbling.

Listen for abnormal noises while spinning each wheel. Rough or grinding sounds indicate a problem.

What next? Wheel bearings need lubrication to work smoothly. Bearing grease can break down over time, increasing friction and wear.

Grease wheel bearings regularly to extend their lifespan and improve vehicle performance.

Use a mechanics stethoscope for a more accurate diagnosis. Rotate the wheel with the probe in the center of the wheel bearing to hear any unusual sounds. This method pinpoints the wheel bearing issue’s location and severity.


Solution #4: Inspect Brake System

Brake problems can trigger the traction control light and slow acceleration because the brake system is closely linked to it. The brake system must be in good condition for vehicle safety.

Check the brake fluid reservoir under the hood for the recommended level. Remove wheels to check brake pads. Replace worn or damaged pads.

Look for damage or dirt on the ABS sensors. Replace or clean sensors if needed.

Braking and ABS/traction control system issues can be avoided by regularly checking and maintaining fluid levels.

Brake pads are stressed during braking, and worn pads can impair braking. Maintaining your vehicle’s braking and traction control systems by inspecting and replacing brake pads is proactive.


Solution 5: Scan for Diagnostic Trouble Codes (DTCs)

The OBD-II system in modern cars monitors various vehicle performance factors.

If the Traction Control Light is on and acceleration is poor, scanning for Diagnostic Trouble Codes (DTCs) can reveal the traction control system issue.

Why Scan for DTCs:

  • Pinpoint Specific Issues: DTCs are specific codes that highlight the area of concern within the vehicle’s systems.
  • Efficient Diagnosis: Scanning for DTCs eliminates guesswork, allowing for a quicker and more accurate diagnosis.
  • Save on Repair Costs: Identifying the exact problem prevents unnecessary replacement of parts and saves on repair expenses.

OBD-II scanners are easy to use and plug into the vehicle’s port under the dashboard. It retrieves DTCs from the vehicle’s computer and provides a health report. Buying an OBD-II scanner can help car owners prevent problems.

After scanning for DTCs, decode them. OBD-II code databases and online resources can explain each code. This knowledge helps you decide if you can fix the problem or need professional help.


Solution #6: Reset the System

The Traction Control Light may appear due to traction control system glitches. To recalibrate, reset the system by clearing stored codes and irregularities. This works well for minor or transient issues.

When to Reset:

  • After Repairs: Resetting the system post-repairs ensures that the changes made are reflected in the system’s operation.
  • Intermittent Issues: If the Traction Control Light comes on sporadically, a reset may resolve temporary glitches.
  • Battery Disconnect: Disconnecting the vehicle’s battery for a few minutes can serve as a manual reset.

Disconnecting the battery resets the vehicle’s systems. This DIY fix for electronic glitches is easy for anyone to do.

However, disconnecting the battery may reset radio presets and clocks.

After fixing traction control issues, resetting the system lets the vehicle match the new settings. This optimizes the traction control system with updated parameters.


Solution #7 – Seek Professional Diagnosis

Seeking a professional diagnosis is the last and possibly most practical option when confronted with the unsettling situation of a Traction Control Light error.

Improving your vehicle’s stability and avoiding wheel slip are two of the traction control system’s most important functions.

Your safety and the vehicle’s structural integrity could be jeopardized if you try to fix complicated problems on your own or ignore them.

Accurately identifying the cause of traction control problems requires knowledge and sophisticated diagnostic equipment that are only available to professional mechanics and dealership specialists.

Thoroughly inspecting all essential components and retrieving fault codes from the car’s onboard computer systems are part of a full diagnosis.

Compliance with safety regulations and product requirements can only be assured with expert assistance. The precise problem that is causing the Traction Control Light to illuminate and hinder acceleration can be addressed by technicians who are trained to correctly interpret error codes.

How Much Can A Professional Diagnosis and Fix Cost?

A professional diagnostic for a Traction Control Light problem can cost more or less depending on things like where you live, what kind of car you have, and how bad the problem is.

Automotive repair shops and dealerships often charge between $50 and $200 for diagnostic services. Technicians’ time spent inspecting and diagnosing the problem using diagnostic instruments is usually covered by this expense.

After the issue has been identified, the specific parts or components that need fixing and the type of malfunction will determine the repair cost. Repairs for typical traction control problems, including a broken sensor or wire, can cost $100 to $500.

The repair costs could go up to $500 or even $1,000 for more extensive repairs if the problem involves more complex components or systems within the traction control system, like the ABS (Anti-lock Braking System) module or the ECM (Engine Control Module).
