OBD-II is an automotive diagnostic system that was first introduced in the United States in 1996. It is now a global standard, and vehicles built since 1996 are required to have an OBD-II port. OBD-II allows mechanics to diagnose and repair car problems without having to take the car apart. The port is typically located under the dashboard, and plugs into the car’s computer. OBD-II diagnostic tools allow mechanics to read the car’s computer and check for errors. OBD-II also provides information about the car’s performance, such as fuel economy and engine temperature.

This app is mainly for Volvos of years 1996-98 to use with ELM327 bluetooth/Wifi/USB dongle to diagnose, read and even program little bit. To exceed over standard OBDII capabilities (ex. Pxxx codes not being there in case of fault) to read these cars to help diagnose problems. Please check website for latest and more information.

ELM327(V1.4b or greater).
Most problems comes when ELM is not having correctly behaving firmware! Example missing command ATSI which is critical! If you have on ELM327 like device with just black glue chip on board (C.O.B.)..

There will be some errors/bugs as i can test things mostly on my own Volvo and or bench. So when you send that 850log.txt file to me via email (via settings) i look what i can do!

Will be updated based on feedback.
Thanks for your support! I hope this will be useful and i will make it even more useful by time!

I don´t take any responsibility what this app can cause by using it or while using it.
I don´t warrant any things this app says. Many are just best guess by study and will be fixed as noted.
App doesn’t have any tracking of users (location permission i asked due because of bluetooth permissions*) only what Google Play Store does itself(counting etc).

*To access the hardware identifiers of nearby external devices via Bluetooth — scans, your app must now have the ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permissions

*To have Wifi support needed to have next permissions; CHANGE_WIFI_STATE and android.permission.INTERNET.

Whats New In this 850 OBD-II?

– Fixes for wifi based on LineageOS android systems which requires ACCESS_FINE_LOCATION permitted to work correctly.
