Whether you are a full time mechanic, or just a hobbyist, keeping track of all the different OBD-II codes for various vehicles is a nearly impossible task, and while not everyone wants to keep their laptops handy with them, odds are you do have your BlackBerry with you. If this is the case for you, then we have just the app for you, OBD-II Trouble Code Lookup, which allows users to access nearly 11,000 diagnostic trouble codes while on the fly right from their device. Simply select the make of your vehicle (over 20 brands recognized currently), and the code that you have, followed by pressing the search and just like that you are finding out what is going on. The application will create a pop up that tells you what the issue is, then give you an option to dismiss the pop up, or search the web which will give you even more information on the issue. If you are into cars, and like to get hands on and do things yourself, this is a must spend $1.99 for you.
