Look at the dashboard. The service light should be off. If it lights up again, there might be a problem or the reset didn’t work.
Use an OBD-II scanner to check for any error codes.
Regularly checking this light helps keep your vehicle running well and on schedule for maintenance.
What should you do if the service light does not reset?
If the service light doesn’t reset, start by checking for error codes using an OBD-II scanner.
