Equus 3030, February 11, 2010

I bought the Equus 3030 a month ago. My check engine light inconveniently came on the month I needed to get an emissions test. In my state, if your check engine light is illuminated, you automatically fail the test. I bought the 3030 to help diagnose the problem. The 3030 seemed to have the best reviews for the lowest price and the most options. This tool gives you the standard obd2 codes as well as manufacturer specific codes. It gives you the option to clear the codes. And it has some nice software that lets you print up a report and document the situation when your light came on. BE WARNED: Code readers will NOT tell you exactly what component failed on your car! The codes indicate which systems need attention. These systems typically have several components. The software and website will steer you toward the common reasons for failures of these systems. If your problem is not chronic, this tool can clear the code and turn off your check engine light. This reader also has the nice extra of having a three indicator light system that lets you know if your car is ready to pass the emissions test. It show green for "ready to pass"; yellow for an "inconclusive test"; and red for "your car is going to blow up, get it to the shop immediately". Once you clear the code, your car will have to run through several preprogramed tests (different for every manufacturer) before it gives you the green light for the emissions test. If you clear the code on your way to the emissions test, there is a good chance that the test will be inconclusive. It took me a few short trips to the store to pass these tests.

The device is easy to use: 1) turn your key to the 'on' position. 2) plug in the reader to the port (usually around the driver's knee area). 3)Read code(s). 4) Look up codes in instruction book or online. 5) Determine the severity of the problem code and erase as you feel comfortable, or take it to the shop for repairs. Even if you have to take it to the shop, this tool give you a heads up on what the repairs may entail.

There a lot more sophisticated tools that diagnose more systems and give you more options. But this tool is easy to use and has a friendly price. Some auto-parts stores offer to read the codes for freee. Most repair shops will charge you $50-$200 for the same service. For me, it nice to have the 3030, so I can pass the emissions test. As a bonus, I don't freak out every time my gas cap wasn't screwed on tight. GOOD BUY!
