Hi, I have a 2007 Mazda5, 5 speed. My check engine light is on. I connected my innova scanner, could not find anything. Innova customer service tells me that Mazda is not compatible with their scanner. I confirmed this with the emission sticker under the hood. It does not say it is OBD2 certified. I am feeling a bit lost as to how to find the codes related to my "check engine" light. Ant suggestions greatly appreciated.
