First tried it on a 2012 Honda Pilot that has never had a code.  As expected, it showed no codes stored and I was impressed with ease of use and functionality.

Then put it on the 2006 Durango which is showing check engine light, and we know it's a lifter oil pressure issue with the Cylinder management system- when it goes from 8 cyl. use to 4 to save on fuel.  Reader did show 1 code, ok so far so good.  Go to 'read code' option and it gives the $7E8 and $7E9 message.  When those are selected it does not go any further, telling us 'no codes' .    Do we need to do something to get into a sub menu?   This complaint is repeated all over the internet for various cars and readers, but again, this reader promises to support this vehicle we use it on, so ....what gives?  Are we not using the reader exactly correctly?

So much so I will be returning the unit and trying one from a different company, thanks Autel for the inconvenience.
