It does give you code but the website does not give you any "free" explanations. The promoted solution would not accept my credit card so I have no other comment. I would not buy again.

This product was very easy to figure out and use.

I found my problem code and reset it with no trouble whatsoever.

A very complete manual with a good amount of background material to explain the whole OBD code topic.

Says it reads ABS codes. It will not read the ABS code on my 1996 Suburban. May work with newer vehicles, but not mine.

I find the packaging to be very misleading. It says "all vehicles 1996 and newer" and "reads ABS codes". It should say "check to see if this is compatible".

I have used this unit for sometime now and it has been great addition to my garage. I had always kept the updates current. However it was a recent experience that will now force me to seek out another brand of scanner. The 3100 has read every car I have owned and several of my friends cars as well. I now have a vehicle that is ODBII that this unit will not read. It gets an error when following the steps to initiate communication between itself and the vehicle. I checked the unit with my other vehicle which is a prior year to the one in question and the unit worked flawlessly. I contacted the manufacturer and they were very quick to respond, which earned this review a third star. I asked if my particular vehicle was one the unit will not work with. They said their should be no issues with the vehicle.

They then listed the fuses I should check which would interfere with communication. I checked all the fuses in the vehicle and all had continuity. Even at this point I still felt the unit was working but something was wrong with the vehicle. I then took the vehicle to a shop and explained to them how my 3100 would error. They agreed to hook their scanner up to test if it would communicate and not charge me because they would not provide the codes. After seeing their unit work on the vehicle, I tried my 3100 on the vehicle and once again there was an error. They felt it was something wrong with my 3100, so the mechanic hooked his unit into his own vehicle and then hooked my 3100 into it as well and it worked. Confused as I was, he gave me the codes anyway for free.

I explained this to the manufacturer and in a very odd response they told me that I need to check the fuses after I told them I checked all of the fuses listed in the book for continuity. Their response was basically that they are sorry their suggestions did not solve my problem. In other words, they left me swinging in the wind. As I said above, the 3100 has worked great for me in the past. It is pointless to continue to have this unit if it does not work on all ODBII vehicles and the manufacturer seems to be unaware of this. My advice would be "buyer beware" when purchasing this unit and make sure you can return it under the provision that it will not communicate with your vehicle.

I've used this code reader to diagnose problems on both my 1998 Outback (and God knows that car spits out plenty of codes!) and my 2001 4Runner. Logical and simple to set up and use. Highly recommended for the shade tree mechanic.

This is my first code scanner. It reads OBDII, including CAN format. I've only used it once to date, but it told me everything I needed to know and more. The manual that comes with it is very informative, describing not only the codes themselves, but pending codes and monitors. This little device will tell you about all those things, so not only will you know which codes have popped, but which might pop soon. Far more features that the more common orange-colored brand for the price. Highly recommended.

*** Edit for 2013: in the middle of last year the screen on my reader died, but not before several years of good service. I couldn't bring myself to throw it away, but did replace it with a unit that interfaces with my laptop (much cheaper, btw). This unit rode around in my car for a couple of months before I decided it was time to throw it out. Before pitching it, I gave it one more chance--it had miraculously fixed itself. Now I have two useful code scanners, though this is a much more useful one for car shopping--no laptop required. I've learned on two separate occasions now DO NOT go shopping for a car without a scanner. There are far too many unscrupulous dealers and owners that reset the codes just before a potential buyer shows up. This scanner will tell you that several monitors have not run yet, which is a dead giveaway that something is up. In this way, any scanner that can check monitor status will save you thousands.

An excellent product, easy to use and the instruction manual was very detailed and easy to understand.

Reasonably priced compared to other units.

I would recommend it to any first time user.

The freeze frame feature is invaluable in pinpointing the problem without purchasing two or three senders, sensors etc.

I purchased this unit to diagnose a check engine light on my 1996 Mazda Miata, but the unit was unable to retrieve a code. After contacting the company's support line, I found out that it has known problems with Mazdas made around then.

Not necessarily the fault of Equus -- Mazda may not have implemented the OBD-II protocol correctly early on. Either way, it doesn't work on 1996 Mazdas. I've heard good things from other owners of this code reader, so I'm still giving it a good score.

The code reader is a very good device with an excellent price. I fix my car and I saved money. The diagnostic for a car is almost 80 dollars in the auto repair shop, with that money I bought my own code reader.
