Connected almost immediately and effortlessly.

Was able to scan and pull up a P0455 code on my wife’s car and let me clear it. I downloaded this app today after my other goto app wouldn’t see any error codes and obviously not let me clear what it couldn’t see.

Great free app, allows you to clear codes for free!

I don’t understand all of the 1-2 star reviews, mine connected right away.. After trying DashCommand premium ($16) and not having that recognize my 2007 Civic Si, I downloaded a few free apps to try. This was the only one so far that let me clear codes and actually get rid of the check engine light. The car didn’t have to be on, it just needed to be in the position before cranking the engine. EOBD-Facile and Auto Doctor both required subscriptions to clear codes or just wouldn’t connect.

Does not clear codes

I have 22 faults on the car and it says it clears codes but it actually does not. If you check the codes with a real obd2 reader it shows they are active.

The codes are only cleared on the app. It can remove the cel but it the faults.

Developer Response ,

Sorry for inconveniences. We always happy to help and answer all mailed requests for support. Please contact our support team directly with in-app options (i) - Contact us, and describe the case in detail. Please note, that app reading and clearing only codes described by OBD-II related to Engine and Emission systems (Check Engine Light at dashboard). Please also note, that before clearing code one should repair the car and fix the source of the error. Sincerely yours inCarDoc Team
