Faults meanings are linked to on-line repair information advice to help you fix the problem or help you explain it to your garage.

Unique pop-up display that explains code acronyms, for example AECM (air bag electronic control module)

New codes are added using our unique automated update function.

Be part of the best fault codes app, currently growing at the rate of 750+ new installs per day!

For use in conjunction with a basic low cost code reader ($15) if your vehicle does not display the code itself.

Great app I think a lot of people don't realize that once you put the dtc in if you hold your finger on the screen it will open up another page where you can hit fix and it would tell you how to correct problem

Database ONLY don't mistake it for something that will connect to an ODB scanner. With that in mind the database is good, the ads are not, main screen ad could be confused as the button needed to start.

fantastic app. very convenient when used with an OBDII reader, it saves a alot of head scratching time and puts you into problem solving mode.

This looks like a scam to me. Auto updayes as soon as you install it, then theres no true software or ability to connect to a OBD adapter.

No instructions. Cannot get it to bluetooth over to the supported OBDLink ScanTool MX Bluetooth. I do have other code readers that will successfully pair to the obd scan link.

Good for P codes, pretty impressed. I use Inpa and Ista BMW software for diagnosis so don't really need P codes, but this will recognise most manufacturers codes, saves hunting online for codes, quick code recogniser 👍
