The Actron CP9135 AutoScanner Diagnostic Code Scanner with its on screen definitions allows the user to determine why the “Check Engine” warning light is on. It also lets the user know if the onboard diagnostic computer (OBDC) has collected enough data to allow the vehicle to pass inspection. After the cause of a fault has been corrected, the vehicle must be driven long enough for the computer to log sufficient data. Bringing a car for inspection without complete data in the computer will result in the car being rejected (at least in Massachusetts).

The Actron CP9135 is no longer being sold by the manufacturer. Newer models with more capability are now available - but they are much more expensive. I am very happy with my purchase. It provides me with the information I need to maintain my cars, and I was able to buy it through Amazon.com at a reasonable price. The CD which accompanies the scanner contains a wealth of information about error codes, but it is not used interactively with the scanner. The Actron CP9135 has no computer download (or upload) capability. Upgrades require a chip replacement. Whether or not these exist now or will be available in the future I do not know.

In summary, the Actron CP9135 AutoScanner Diagnostic Code Scanner is a good buy if you want better insight into your vehicle’s diagnostic status, and you like having your own tools. In eastern Massachusetts any AutoZone store will check your error codes for free, so owning your own scanner is a luxury, not a necessity.
