850 OBD-II for PC

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.



Requirement!:
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.).. It works only with standard OBDII stuff and not with this app most functions. App has pop up to notify user if this detected.


Support:
850/900 series
On these models Electronic Control Units as Yazaki dash, M4.3, MFI system (LH-jetronic 3.2 & EZ129K), Fenix 5.2, ECC(A/C) and Cruise Control are not reachable by ELM327!
(VDO dash and M4.4 are OBD capable!)

S40/V40
These series has still lot of work to be correct.

C70/S70/V70/XC70, S90/V90 series


1999-2000 years were developing years as example V70 models are working partially like not to connect to Engine ECU or ABS due them being newer CAN Bus systems BUT! VGLA, Immobiliser, SRS, AW 50-42.. are connected due them being on older systems still.

==============



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.
