I went to the Harbor Freight Site and Key-worded "Code Reader"

There was like 5 or 6 different Models that came-up.

Which is the one you should have for monitoring the system in our Monte's?

What makes one better than another?

 

Hey Rick, I have a Actron model cp9135 which does quite a bit. Take a look at this web site, Maybe it will answer some ?'s http://actron.com/product_category.php?id=249 Hope this helps.
