This app is the most complete OBD II (EOBD) diagnostic trouble code definitions database. This is an ad-supported Lite version, which contains only 2553 description of generic codes (P0...). If extended code is accessible in full version, you will get message "This description is available in FULL version" If you want to get all descriptions you can buy FULL version, which contains more than 18500 error descriptions for almost 50 car manufacturers. Very simple to use! You don't even have to select your car model. Just enter your fault code and app will show you all supported descriptions. No Internet connection needed, no longer spend hours to search for single code description, looking at check engine light. If you have cable, bluetooth or WiFi OBDII code reader (ELM327, PLX Kiwi or any other) you need this app for code description because most of code scanners does not contain full DTC (diagnostic trouble code) database and displays only meaningfull numbers. Be prepared for any troubles wherever you are! You can select and copy error description with simple long press on text, and then paste it in SMS, e-mail or wherever you want! If your car supports OBD II or EOBD, then you can already use almost 5000 generic OBDII codes. These codes are from PowerTrain series (P0XXX, P2XXX, P34XX), Body Series (B0XXX), Chassis series (C0XXX), Network series (U0XXX, U2XXX, U3XXX). Also there is a list of more than 13500 additional manufacturer specific codes. Supported manufacturers with specific codes: Acura Alfa Romeo BMW Chrysler / Dodge / Jeep Citroen / Peugeot Daewoo Fiat Ford Geo GM (Buick, Cadillac, Chevrolet, GMC, Hummer, Pontiac) Honda Hyundai Infinity Isuzu Jaguar Kia Lamborghini Land Rover Lexus Lincoln Mazda Mercedes Mercury Mini Mitsubishi Nissan Oldsmobile Opel / Vauxhall Plymouth Porsche Renault (DF codes) Saab Saturn Scion Subaru Suzuki Toyota Volskwagen Audi Group Volvo Note, that it is impossible to create complete OBD DTC database. Manufacturers are adding new codes and changing old ones. So if you cannot find your code or if you think that some code not correct anymore, please write us!
