The Equus 3120e Innova CanOBD II/I Diagnostic Code Scanner Tool Kit is an enhanced scan tool that is loaded with many professional features. If you are new to diagnostic scanners, this handy tool connects to your vehicle, scans various parts of your car, truck or SUV, and retrieves a list of diagnostic trouble codes (DTCs) and code definitions from your vehicle's computer. But even if you're a veteran to scanners and auto repair, you'll be impressed with the new functionality that Equus has added to the 3120. This device not only scans your vehicle, it also allows you to freeze-frame live timing and pinpoint your vehicle's problem. Instead of having to recreate a scenario over and over again, you can now playback the timing to scrutinize all the data and make a clear diagnosis. Combine this with Internet connectivity and the ability to interface with a PC, and you have a powerful, professional diagnostic scanner in the palm of your hand. As government agencies establish more stringent emission laws, vehicles continue to become more sophisticated for maintenance and repairs, forcing professional mechanics, DIYers, and consumers alike to find easy-to-use tools for diagnosing their vehicles.

Many tools have already been developed to access these powerful on-board vehicle computers, but the Equus tool is particularly simple to use and surprisingly affordable. It is designed to be used by almost anyone, from the weekend mechanic to the ASE master technician. The 3120 CanOBD II/I scanner is designed to retrieve diagnostic codes in all OBD II (1996 and newer) and some of the most popular OBD I (1982 to 1995) vehicles. The scanner features a unique patented all-in-one screen display and LED display for quick OBD I/M emissions check, so you'll know if you're ready to pass those ever-increasingly stringent laws. Equus built the 3120 to display 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 a handy memory for off-car review and analysis. The 3120 is also equipped with the ability to connect to your PC. With the included cables and software you can connect the scanner to your computer to generate, print, and save detailed diagnostic reports, and even update the 3120 via the Internet.

The 3120e links to all OBD II protocols including CAN (Controller Area Network). The tool captures and displays freeze frame data that will help you pinpoint and troubleshoot any problem. This device is equipped to retrieve the following OBD II 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.
