Bests & Worsts Reviews from Amazon

I am grateful to have had this scanner on hand. My car was due for tag renewal and it kept failing emissions due to the "no communication" with the computer. I did this 3 times at different service stations. The emissions station uses OBD2 scanners to pass or fail cars. There has been no "check engine light" on in my car. Sure enough, when I hooked my car up to this personal scanner at home it created a "link error" message. This would discourage a lot of people and make them think it wasn't working properly. However, I knew it had nothing to do with the OBD2 scanner, and everything to do with my car since it wasn't able to communicate with the emissions OBD2 and this personal scanner. I was able to do some research online and tweak a few things at home until it was able to communicate with this personal scanner. It turned out to be as simple as changing out a fuse!! After it was able to communicate with my personal scanner I knew it was fixed and it passed emissions!! This scanner saved me hundreds of dollars from bringing into a shop to be fixed and repaired. I probably would have paid for unnecessary repairs in the process. Very grateful and happy to have this product!!
