How to Reset Traction Control Light

Step 1: Locate the OBD-II Port

First, locate the OBD-II port in your car. It’s usually under the dashboard, near the steering column. If you’re not sure where it is, check your vehicle’s manual or do a quick online search.

Step 2: Connect the Diagnostic Tool

Grab your handy diagnostic scanner or OBD-II code reader and plug it into the OBD-II port. Just make sure your car’s ignition is in the “off” position before connecting.

Step 3: Power On the Diagnostic Tool

Turn on the diagnostic tool and wait for it to establish a connection with your car’s computer system. It might take a moment, but once it’s connected, you’re ready to go.

Step 4: Get the Trouble Codes

Use the menu options on the diagnostic tool to retrieve the trouble codes stored in your car’s system related to the traction control. These codes are like little clues that can help you figure out what’s causing the light to come on. Jot them down for future reference.

Step 5: Clear the Trouble Codes

Look for an option in the tool’s menu that lets you clear or reset the trouble codes. When you find it, go ahead and select it. The tool will do its thing, clearing out those codes like a magic eraser.

Step 6: Disconnect the Diagnostic Tool

Once the tool has finished clearing the codes, it’s time to bid it farewell. Safely disconnect it from the OBD-II port and put it aside. Give yourself a little pat on the back for a job well done so far.

Step 7: Test Drive the Vehicle

Hop into your car and take it for a test drive. Pay attention to how it handles, accelerates, and brakes. If the traction control light stays off and everything feels normal, that’s a great sign. You’re on the right track!

Step 8: Keep an Eye Out on the Dashboard

After resetting, keep an eye on that traction control light. If it stays off and doesn’t come back on, you’ve successfully reset it. However, if the light reappears shortly after or keeps coming back, it’s a sign that there may be an underlying issue.

Common Reasons Why The Traction Control Light Can Come On

1. Wheel Speed Sensor Issues

These sensors keep a close eye on the rotational speed of each wheel. If one or more sensors go haywire or start sending wonky signals, it’s a surefire way to trigger the traction control light.

2. Faulty ABS System

The anti-lock braking system (ABS) and traction control system often work hand in hand. So, if there’s an issue with the ABS system, like a cranky sensor or hydraulic hiccups, it can set off the traction control light too.

3. Damages Wheel Speed Rings

These toothy rings hang out on your wheel hubs and help the wheel speed sensors do their job. But if they’re damaged, missing some teeth, or clogged up with debris, it can throw a wrench in the works and activate the traction control light.

4. Brake System Problems

Your braking system plays a vital role in the traction control dance. If your brake pads are worn out, a brake caliper goes rogue, or you’re running low on brake fluid, it can throw off the proper functioning of the traction control system and cause that light to shine.

Importance of Diagnosing the Underlying Issue Before Resetting the Traction Control Light

1. Safety First

Your safety and the safety of your passengers should always come first. When the traction control light pops up, it’s your car’s way of saying, “Hey, something’s not right here.”

Ignoring or simply resetting the light without diagnosing the issue could compromise your safety, especially when you encounter challenging road conditions. It’s like putting a band-aid on a deep wound instead of getting proper medical attention.

2. Prevent Further Damage

That little light is a clever early warning system, alerting you to potential issues within the traction control system or related components. By diagnosing the underlying problem, you can catch any hidden damage or malfunctions before they worsen over time. Think of it as getting ahead of the game and preventing small hiccups from turning into big headaches. Your wallet will thank you too!

3. Preserve Your Ride’s Performance

We all want our vehicles to perform at their best, right? Well, a malfunctioning traction control system can throw a wrench in your car’s performance gears.

It could mess with stability, handling, and even your ability to accelerate or brake smoothly. By diagnosing and resolving the underlying issue, you ensure that your beloved ride operates as intended, keeping you in control and enjoying the open road.

4. Avoid Chain Reactions

Remember, your vehicle is a complex network of interconnected systems. A problem in one area can set off a chain reaction of issues in others.

For example, that traction control light may be triggered by a faulty wheel speed sensor, but that sensor’s malfunction could also affect your anti-lock braking system (ABS) or electronic stability control (ESC).

By diagnosing the issue, you uncover any potential domino effects and address them all at once, saving you from future headaches.

5. Time and Money Well Spent

Sure, it might seem like a hassle to diagnose the problem instead of quickly hitting that reset button and moving on. But honestly, it’s a worthwhile investment of your time and money.

By taking the time to identify the true cause of the issue, you avoid wasting time on temporary fixes or resetting repeatedly.

Plus, you’ll avoid any unnecessary expenses that could pop up if the problem worsens or affects other parts of your vehicle.


And there you have it! You’ve reached the end of this post on how to reset the traction control light. We hope you found the information practical and helpful in tackling this common automotive issue.

Remember, resetting the traction control light can provide temporary relief, but it’s crucial to keep in mind that it’s not a permanent fix.
