Equus 3100 Innova CanOBD2 Diagnostic Tool

Works as advertised. For the price it rates 5 stars. The unit paid for itself in the first use. The Equus web page is a decent resource.

The diagonstic code reader is a "fun" tool to use. It is amazing to see how it checks out the functions of your engine. Therefore when you go to the garage you can speak to the mechanic with some degree of knowledge!Also you can know when you need not go to a garage, such as when you bought "bad" gas!

This tool is so easy to use. Just plug it in and it tells you everything you need to know to find out what is making the "Check Engine Light" come on. It will tell you the code and an explanation right on the screen. This is a must have for anyone buyimg a used car as it also tells you potential codes. Best part is it will clear the codes when you are done looking at them.

Very easy to use, book is fairly thorough with codes. The software is somehwat confusing, Im still working on that. Overall though, a very good product.

I purchased this product to diagnose a check engine light on my 2006 Ford F-350 6.0 Litre Diesel. Prior to purchasing the unit I replaced my breather filter. The vehicle had close to 20,000 miles on the original filter. This is what apparently flagged the check engine light during a hard acceleration up a steep grade.

I received the product very quickly (sooner than expected). I read the booklet enough to use the product (very important as improper use may damage vehicle and/or reader). Code reader indicated what the problem "was" (I had already fixed the problem but was not sure without the code reader). I researched the error code on the internet and then cleared the check engine light. All went as advertised. Without this device I would have needed to make a trip to the dealership for nothing (of course with much expense). This device paid for itself in its first use. Great product. Easy to use.
