anyone who has had the check engine light pop on while driving

This gadget is the most valuable tool I've added to my tool box in the last 10 years! I have used it for several different cars and trucks with no problem. It's as easy as 1,2,3. One, plug the device into the OBD connector under the dash. Two, turn the key to the "run" position,(but don't start it). Three, press start and let it scan! Less than 30 seconds later, you have the codes to get you pointed in the right direction for repairs. The included booklet has hundred of the generic codes listed with descriptions, and when that wears out or get lost, you can always put the codes into google for an answer. This thing is quite durable for an electronic tool. I took it to work to scan a co-workers truck and it accidentally fell out of my lunch box and tumbled down two flights of wood stairs! It still worked fine. One word of caution: If you go showing this to all you buddies, be prepared to be asked repeatedly to scan their cars, bring it to work, borrow it for the weekend, etc. At twenty bucks, anyone who has a car should own one. Your not as likely to get screwed at the shop it you take the car in and tell the mechanic: It's throwing a P0305 code for a misfire on #5, could you check it out? Rather than "my car is running rough" Also I have found this unit to be EXTREMELY USEFUL when looking at pre-owned cars to purchase. You can scan the car for a clean bill of health, and view the emissions readiness status. If it doesn't show "ready" you can assume someone cleared the codes recently. No one wants to buy a car and have the check engine light come on the next day! Been there, done that. Seriously buy one today and stop guessing!

As with anyone who has had the check engine light pop on while driving, my heart jumped to my throat when that baby lit up my dash on the way to work. And then it splashed back down to the pit of my stomach...hard! I guess it is the not knowing of what is hurting my little commuter. I wanted to know. This brought on the search for a dependable, but not expensive, scan tool to find out on my own what the heck was going on. I found this little jem and decided to give it a shot based on the mostly positive reviews it had. NO REGRETS!
This product worked without any glitches. My vehicle is a 2003 Hyundai Elantra GLS and I think the hardest part of the process is finding the link connector in the car (it is down below of the steering wheel under the driver side dash, if anyone is interested, you have to feel for it because it is not visible). Once I found it though, it was all down hill...in a good way. It fit perfectly and worked as stated in the manual.
Just follow the steps indicated and you will get the info you need. In my case, all I was looking for was the reason for the check engine light to turn on. I got my answer with this little scan tool. In less than five minutes I got the DTC code (this is explained in the manual) that set of the MIL. Once I got the code, I went straight to the auto shop and told my mechanic what I found. I have a good honest "guy" that was surprised, but also pleased, that I had pin pointed the problem for him.
But, the tool also gives more info on the car than just the problem codes. It can pretty much give you the status of most of important components in the car. It was a relief to find out my car was in great shape, except for just one code. Very much a relief.
Well, from my positive rating, you can figure out that I definitely recommend this producted. It is a simple, but valuable tool to have if you drive every day and depend on your car. I have used it only once, and will be happy if I don't have to use it again. I mean this in a good way, but if I ever get a check engine light, it won't freak me out because I have my own diagnostic tool to see what is going on with my beloved 4-banger!

Note: The manual comes with a list of generic code definitions. Once you find the code, you can use their listing, or look it up on the internet. I did both just to verify.
