Autoscanner CP9135
I use to advocate the 9135for the most standard scan tool. This autoscanner cp9135pocket scan is generally the exact same reader with an added characteristic of an emergency sign.
When you hook up this automotive code reader and click the read codes button, it will show the stored code and an arrow will position to green, yellow or red.
This will supply you an indication of whether the value is a serious matter or just a minor trouble. The one drawback to this car code reader is that it does not display on screen meanings.
The system does come with a CD that consists of all of the requirements so you will have to write the code down and then look it up to find out exactly what the code means.
This unit is perfect for someone who wants to read and remove codes and find out if their auto is in danger. For a few us dollars more you can see the review of the 9175 scan tool that contains on-screen code definitions.
