How do you turn off service engine light on Honda Ridgeline?

To turn off the service engine light on a Honda Ridgeline, first, ensure that any existing issues that triggered the light are resolved. You can then disconnect the negative battery terminal for about 15 minutes to reset the system. Alternatively, using an OBD-II scanner can help clear the error codes that triggered the light. If the light reappears, it may indicate a persistent issue that needs further diagnosis.
