What are the initial diagnostic steps to take for a check engine light on a 2024 Kia Carnival?

When faced with a check engine light on your 2024 Kia Carnival, it's essential to approach the diagnosis methodically.

Pay attention to any unusual noises or odors while driving, as these sensory clues can help identify the problem. If the light persists, using an OBD-II diagnostic scanner is a practical next step, as it will allow you to retrieve specific error codes from the vehicle's computer, guiding you toward the source of the issue. Finally, don't overlook the owner's manual, which can offer valuable insights into what the check engine light signifies and suggest manufacturer-recommended troubleshooting steps. By following this structured approach, you can effectively narrow down the potential causes of the check engine light and take informed steps toward resolving the issue.
