It will either reset by itself or you can use a scan tool or code reader to reset it once whatever is causing it to come on is fixed. So you should get the trouble codes retrieved to find out what is causing it.

Hello FTD 1108,

If you decide you would like to conduct the scan yourself here is a link to an article from this site that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us with the code number(s) so that we can further assist you. We are always happy to help.
