Best OBD2 – EQUUS-INNOVA 3100 OBD2 CAN/OBDII Code Reader

Description:    The Innova 3100 CanOBD2 Diagnostic Tool is a good choice for car owners but it also has a lot of professional features. This scanner connects to 1996 and newer vehicles and retrieves a list of diagnostic trouble codes (DTCs) with definitions from your vehicle’s computer. You can also view freeze-frame data which shows the condition of the vehicle when the code was set which makes diagnosing a problem easier. Combine this with Internet connectivity and the ability to interface with a PC, and you have a powerful, professional diagnostic tool.  Many tools have already been developed to access these powerful on-board vehicle computers, but the Equus 3100 is particularly easier to use than most. It is designed to be used by anyone, from a DIYer to the ASE master technician. The 3100 is designed to retrieve diagnostic codes in all OBD2 (1996 and newer) vehicles. The tool features an all-in-one screen and 3 color LED display for quick OBD check, so you’ll know very easily if you’re ready to pass an emissions/smog test. The 3100 displays on-screen DTC definitions and user interfaces in English, Spanish, or French, and the trilingual language selection is accessed via a simple menu command. This device also stores diagnostic codes in its memory for off-car review and analysis. The 3100 is also equipped with the ability to connect to your PC. With the included cables and software you can connect the tool to your computer to generate, print, and save detailed diagnostic reports–plus you can even update the 3100 via the Internet.  The 3100 links to all OBD2 protocols including CAN (Controller Area Network). This device is equipped to retrieve the following OBD2 diagnostic trouble codes (DTCs): Generic Codes (P0, P2, P3, and U0) and Manufacturer Specific Codes (P1, P3, and U1). In addition, the tool features an automatic refresh feature that updates data every 30 seconds when connected to the vehicle. This helps verify that your repair has worked.

The reviews for the Equus 3100 Innova CanOBD2 Diagnostic tool were almost all positive.  Many customers commented on how easy it was to use compared to other OBD2 scan tools saying “I am a professional Technician. This little handy dandy tool is fast, easy, and gets to the point of the problem with little to no issues” Well made, Ive had mine for a few years now, its far easier to use then most ‘top dollar’ scan tools”.  They also liked the amount of featured they got for the price.  One of the things that kept popping up was the fact that it can clear codes, this isn’t always found in the less expensive models.  Proffesionals seem to like having this tool around also, because it easier than hooking to a laptop for every car.  They can just keep it in there pocket.  “I am a professional Technician. This little handy dandy tool is fast, easy, and gets to the point of the problem with little to no issues”.  Now for the negative side, there wasn’t many complaints. But one thing that was repeated over and over was the following. “The problem is that you have to pay for the report”.  I did some research and found that the repair solutions site is free of charge and so is the diagnostic report.  But there is an option to receive an advanced more high tech report and it cost 15 dollars.  Some also didn’t like that it doesn’t have a backlit screen like some other OBD2 scanners.   But there wasn’t many negative reviews all-in-all.
