Rated 5 out of 5 by shadmaster3 Very good for the money! Does multiple things in diagnosing check engine light problems. I don't use their software because you have to pay to get code meanings. Go online and find those for free. 02/19/2011
Rated 5 out of 5 by IslandWarren Helpful Money Saver This product works quickly...just plug it in, turn the key to "On" (don't start engine!), and the Equus 3030 will have all your car computer's data. Then you just take it to your computer, plug it into your USB port, and it will open the software (you must install it from CD) that shows you what the numeric codes mean. For instant detailed instructions on how to fix it, it costs US$14.99 (a bit more than the videos and info available "before my purchase" had said). You can use the software for up to 3 cars you register into their system, and use it up to 6 times per month for free. You can use this device to clear your "Check Engine" light once the problem is fixed, and if the problem reappears, you'll know you still have the problem (sometimes it takes several days for the light to come back on). 09/24/2010

Rated 5 out of 5 by DuaneFromTucson Everyone should have one You don't need to be a mechanic to save money with this. I'm no mechanic and I saved money.I had been thinking about getting one because I bought my kid an old chevy s10. Thought I might try to do some things myself to save some money (which remains to be seen). But... my 2006 Toyota automatic started shifting really hard. I thought I would have to have the transmission replaced. I order this online from Walmart, I think Sunday evening, and had it hand by Thursday.(The shipping must have been a mistake because it was almost nothing and shipped right to my house. But I digress.)I immediately stuck this scanner on my Toyota and got the code, which turned out to be some solenoid in the engine oil pan area, inside of course. I kept searching for the code and “hard shift” etc, on the internet until found an issue with the Toyota PCM/ECM module (whichever it is). It turns out that that the code from the scanner along with the hard shift issue was in a Toyota bulletin and they were replacing this module up to 96 months under warranty because it had to do with emissions and the gov’t was involved I believe (I don’t think they would do it for free otherwise.I saved myself several hundred dollars, I betting well over 500 bucks because the knock-offs online were going for $300, just for the part.This is why I say everyone should have one. Oh, not to mention that Toyota charges $89 just to “diagnose” the problem, which took all of 3 minutes to get the code.Any scanner tool would give me the code, but for the price and the features (which includes internet firmware upgrade via the supplied USB cable), you can’t go wrong with this model.I put it on my kid’s “new” s10 and it told me I have an issue with an air intake temperature thingy, which I have located. and will be replacing. It also lit the red LED saying this car will not pass emissions testing. Nice to know before going to get tested.There is a freeze frame feature that I am going to try on my kid’s truck and see what I can figure out. Seems to have a lot of features for the price. 11/15/2010
