Query: Great Product

The Equus 3110 Innova Diagnostic Code Scanner offers an easy, effective way to troubleshoot OBD II vehicles. This powerful and rugged tool quickly reveals the cause of "Check Engine" light warnings on any vehicle. I was fortunate enough to have bought this diagnostic device at a great affordable price. I was able to diagnose the problems of my honda accord 2002 and saved thousands of dollars that would had cost me by taking it to a auto mechanic. I highly recommend this product to anyone willing to fix their own vehicle. The most important thing is that you learn in the process.
