Perfect

With the blend of features and the price point of this unit, you will not find a better deal. Assuming your looking at these reviews you probably fall in to two main groups. 1. Someone who is having issues with their vehicle and 2. Someone who is really into cars or working in automotive towards being a mechanic. If you fall in the first group and just want to know why the check engine light is on, you can go to a major auto parts chain like Advance or AutoZone and they will tell you why in an attempt to sell you the parts to fix it. No sense spending money on a scanner if thats all you want. If you want the power of knowing and not have to go out of the way then consider a pocket scan which is cheaper. For most people you will need to subscribe to Alldata or Chiltons online, or buy a book like Autodata's diagnostic trouble codes to solve some of the problems with your vehicle. The scanner won't do it for you or put it in laymans terms. This scanner is more for group 2, this does the i/m readiness test for emmissions as well and is a solid entry level scanner. If you work in the field I would suggest getting a unit with enhanced obd capability if you can afford it.

Save Yourself MONEY!!!

Autozone loans these out for free and runs your car through one of these for free, but I think it's great to own your own. Mechanics charge like $60 to read your computer code, and another $60 to erase it. It's better to just do it yourself with this lil machine. Takes less than a minute to erase your code!

Almost mandatory for modern vehicles!

The engine in my 2000 Ford F-150 Supercab started dying frequently, the dreaded "check engine" light came on and I did not want to take another $$$ trip to the dealers service department. So I do a little research on OBD and bought an Actron CP9135 OBDII AutoScanner at an excellent price. Plug it in, retrieve the "P1507" code, which translates to "Idle Air Control System Underspeed Error (Ford)". I check the IAC sensor and discover it's not plugged in right. I fix this connection and the problem disappears! If you have a modern (post 1996) vehicle and you do a little of you own auto work (turn a wrench now and then) you need this OBD box. Actron makes an excellent product at a very good price. (If you have an check engine light on - you need a OBD box!)
