Hmmmm....with an Android phone, you can use the (free) Torque app + one of these and check/clear codes for $44.00. I've had one about as long as I've had my truck and it works like a charm.
How cool is THAT...
I had no idea...
On the other hand, I don't have a cel phone, android or otherwise, & not likely to have one in the foreseeable future.
So I'm kinda stuck with the Aero Force gizmo, for now anyway.
