Perfect for a DIY or novice to diagnose your own c

[This review was collected as part of a promotion.] What a lifesaver the CarScan Adviser from Innova is! My engine light was on and this little gem worked perfectly. You just plug it in and turn your car on and it tells you the code and how quickly it needs fixed. You don't need the app for the code, but the app had flawless integration with the unit and it even showed me the part I need and where I can get it. The display is nice and bright and gave me more stats than I needed. I also checked my battery since it was so easy while plugged in. Love this thing.

Worked welltf

Check engine light came on. Opened and tightened the gas cap, but the engine light remained on.plugged in the diagnostic tool and used the associated app which gave me the error code. turned out to be a minimal issue in the emissions system. Light went off after using the tool. saved quite a bit of money without having to go to a car diagnostic service station
