OBDII Trouble Codes

This app is the most complete offline OBD2 (EOBD) diagnostic trouble code definitions database. It contains more than 18500 error descriptions. It is the most full database in market.
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. OBDII trouble code lookup has never been easier.

If you have cable, bluetooth or WiFi OBDII fault code reader (adapter) (ELM327, PLX Kiwi, OBDLink 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! (Android 3.0 and later only)

If your car supports OBD II (OBD2) 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

Note that it is impossible to create complete OBD DTC database. Manufacturers 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!You have to use special scantool for connecting to OBDII scanner (for example, Torque Lite, Torque Pro, Dashcommand or Car Gauge)

Waste of money. It doesn't give you any more info than a quick Google search. Actually, it gives you way less info. Just the title of the error. It doesn't go into detail, such as "out-of-range performance". Don't buy this app.

Great when you need it

I like it. It's handy. People comparing it to free ones is too funny. It's only a few bucks for it, that's almost FREE. Some of the complaints are ridiculous. If you want readings like the high dollar OBDII, You Gotta Buy One

Amazing tool. Don't have to go to my Desktop PC to check codes anymore. I can do it from my cellular phone and start with the reparation asap

Really nice app but 4 stars because it could have the option of choosing other languages. Other than that I would give even 6 stars. I living it

This app comes in handy for looking up code descriptions when you remember them or someone asked what a certain code means. Have used the app on several occasions for this purpose. Easy and simple design to find out what you want to know.

Great to use and straight forward. No immediate problems.
