Actron PocketScan Diagnostic Code Reader
The "Check Engine" light has long been a thorn in the side of car owners, requiring an expensive trip to the garage to get rid of it. The Actron PocketScan Diagnostic Code Reader ($40) lets you retrieve trouble codes from your vehicle's computer on your own, giving you valuable diagnostic information, and letting you clear the codes and turn off the light. Of course, for more pressing matters you'll still need the help of a mechanic, but at least now you'll know exactly what's wrong with your ride before you take it in for repair.
