Autel MaxiScan MS409 Code Reader I like it.
I have only played with this thing a couple of times on my Expedition and on My Honda CRV.

Man that took some research to find the plug in module on the Honda. Its actually accessible from the passenger side, just right of the vehicle center line.

Any way, I have no Check Engine Lights on at this time (a good thing).

But this scanner seems fairly intuitive to use. It will also show you codes for pending problems that maybe don't yet warrant the system to turn on the CEL.

The codes are right there in the scanner, with a description so you don't have to look them up in a manual. You can also find the codes on the internet at several different web sites.
