I recently stumbled across a video describing how to access a diagnostic program built into my odometer. Some of the readouts are obvious , but most are a mystery to me. Is there a list of each menu and what it means? I’ve tried goggling it but have not found anything that talks in detail about it .. please help!!!! I have a 2001 3.8 V6 Thank you
