I found something interesting that could help you. It's called "BlueDriver Bluetooth Pro OBDII Scan Tool for iPhone & Android".

I leave you more details below.
Using the same Identifix database professional shops use, BlueDriver will match your vehicle's make, model, and trouble code to a specific fix from a database of over 30 million fixes. Your Repair Report will always contain fixes that have been verified by Certified Professional Mechanics, so no more googling unreliable fixes that waste your time and money.
With the BlueDriver Sensor plus the free BlueDriver App (available on both iOS and Android), you get a complete vehicle repair solution. No other scan tool or code reader offers this level of insight into how to fix your vehicle.
BlueDriver reads (and clears) all the codes the other guys read and the ones they don't. BlueDriver's Enhanced Diagnostics give you complete access to information normally only accessible to professional mechanics on their most expensive scan tools.
What are ENHANCED diagnostics?
All vehicles with an OBD2 port are required to output basic information when the Check Engine Light comes on. However, a lot of important information (such as ABS, Airbag, Climate Control, etc.) is left behind by other scan tools and code readers. Only BlueDriver gives you the complete set of diagnostics on a wide range of manufacturers.
