Actron CP9135 AutoScanner Diagnostic Code Scanner with On Screen Definitions for OBDII (Post-1996) Vehicles

The only reason i gave it only 4 stars is because i've only used it once. But it was easy to use and informed me of the error codes. Great product and cheap too.

UPDATE: used it a second time in July and it would not link up to two different cars. USELESS.

I purchased the OBD2 code reader to help diagnose the check engine light that appeared on my 1997 Toyota 4Runner. The reader was extremely easy to use (just plug the connector into the vehicles diagnostic port) and not only gives you a code but the problem (in my case a misfire on cylinder #4), so I can isolate what repairs need to be done. I am very pleased with the performance and the price I paid at Amazon. I recommend this tool to any home garage mechanic wanting to do their own diagnostics on any vehicle 1996 and newer.

I bought this scanner because my nissan's check engine light went off and on over and over again. I went to an auto store to have them read codes. They read the codes for free, however would NOT reset the light for me. I can now reset my light and also check to see if it is in what is called the "ready" mode for me to get it inspected. Turned off light, got it inspected, and I am good for one more year! I have also reset about 5 of my friend's vehicles for them. Great product and great price!

This is a perfect scanner for those like me who aren't car fanatics but would like to take a more active role in understanding their car. This unit displays code descriptions along with the codes themselves, eliminating the need for a manual and making this a self-contained unit. I am very pleased with this purchase.

This scanner paid for itself the first time I used it. Protect yourself from auto garage ripoffs! I have even helped friends and frankly everyone who needed it to get back at all the auto garages which have ripped me off over the years! It's great to know how your car is doing without paying someone else $80 to do it. Just plug it in and it is very easy to understand and use. Don't bother with the included software.
