    Great Scanner for the Money

    As soon as I received it I tested it on all three of my vehicles. My’ 06 T&C recently had a check engine light, but it did go off on its own. The Udiag scanner picked up on it and said it was a EGR failure, which I already knew. Great, that reading was right on. Next the ’06 Dodge Charger. This one was low on tranny fluid a while back and sure enough, that is what it registered. 2 perfect readings. Now to the ’08 Ford. This one has 90.000 and never had a code show up. And, once again that is what the Udiag showed. Wow, what a great Christmas gift to myself. Glad I purchased it.
