Bench Overview: Quick look at Craftsman 20899 Scan Tool Review. (Innova 3140) in the shop.
I've had this basic scan tool since 2008 and despite some short comings Its an excellent beginner grade tool fro diagnosing your car.
This one has the added bonus of OBD-I connectors so if your into older cars it can help with those too.
