If you’ve noticed the traction control warning light persistently lighting up your dashboard, we’re here to help. In this article, we’ll walk you through the step-by-step process to reset the traction control light and confidently get you back on the road in your Hyundai Sonata.

1. Purchase an OBD-II scanner online or at auto parts stores.
2. Find a safe spot to park your Sonata and ensure the engine is turned off.
3. Locate the OBD-II port under the dashboard on the driver’s side.
4. Plug the OBD-II scanner into the OBD-II port.
5. Turn the ignition key to the “ON” position.
6. Look at the scanner’s display to view the various menus. Select the option that says something like “Read Codes” or “Scan for Errors.”
7. Select the “Scan for Errors” option. The scanner will communicate with your Sonata’s computer and check for any trouble codes, including the one that triggered the traction control light.
8. Once the scanner finishes the scan, it will display any trouble codes it found. Select the “Clear Codes” option. This action will reset the traction control light and any other trouble codes that may have shown up.
9. After clearing the codes, go back to the main menu and re-scan your Sonata to ensure all the codes are cleared. You’ve successfully reset the traction control light if you see “No Codes Found” or something similar!
10. Unplug the OBD-II scanner from the port and turn off your car.

2010 – 2014 Models

1. 1. Get in your Sonata and make sure the engine is turned off.
   2. Locate and pull the hood release lever under the dashboard on the driver’s side.
   3. Walk to the front of your car and lift the hood. You might need to find the secondary release latch just under the center of the hood and pull it to fully open the hood.
   4. Locate the car’s battery and a wrench or socket set that fits the battery terminal bolts.
   5. Loosen the bolt on the negative (-) terminal first. Just give it a few turns; you don’t need to remove it completely.
   6. Loosen the bolt on the positive (+) terminal second.
   7. Reset the system by draining the residual charge for 15-20 minutes with the battery disconnected.
   8. Reconnect the positive (+) terminal first and tighten the bolt.
   9. Reconnect the negative (-) terminal and tighten that bolt too.
   10. Close the hood.
   11. Get inside the car and start the engine. Let it run for a minute or two to ensure everything is back to normal.

1. Locate and open the fuse box under the dashboard on the driver’s side.
2. Find and remove the traction control fuse. You’ll want to check your car’s manual or the fuse box cover for a diagram showing which fuse is which. Look for one labeled “TC” or “TCS.”
3. Wait for a minute allowing the system to reset itself, and any lingering electrical charge will dissipate.
4. Put the fuse back in and close the fuse box.
5. Start the engine and let it run for a minute or two. This will give the car’s computer enough time to recognize that the traction control system has been reset.
