If that's the only readiness monitor not set you can pass inspection under Federal Law! 1996 thru 1999 models can have two readiness monitors not set and will pass Emissions Inspection. 2000 thru current will pass with one readiness monitor not set. If you have more than one not set on your 2015 model keep the gas gauge between three quarters and one quarter full. Drive normally for a few days. As long as the check engine light doesn't come on the readiness monitors will set and you will pass inspection. Hope that helps! Jim
