This app is mainly for P80 Volvos of years 1996-04 [additional growing support P1, P2 Platform too!] with ELM327 bluetooth/Wifi/USB dongle to diagnose and even program little bit. Exceeding usual standard OBDII capabilities (ex. Pxxx codes not being there in case of fault) to read individual modules directly to help diagnose problems. >>>Please check website for latest and more information<<< Requirement!: ELM327(V1.4b or greater). Most common problems comes when ELM is not having good firmware! Example missing command set. These works only with standard OBDII stuff and not on app most functions. App has pop up to notify user if this detected. Support: 850/900 [S/V90] series Note! Yazaki dash, M4.3, MFI system (LH-jetronic 3.2 & EZ129K), Fenix 5.2, Motronic M4.3, ECC(A/C) and Cruise Control are not reachable by ELM327! S40/V40 models up to year 2004 Lately has been added ABS and Dashboard programming for these models S70/V70/XC70 Mostly all has OBDII support except Fenix 5.2 ECM and Cruise.

P2 Platform year models since 2000+ (and 1998+ S80) CEM, ABS/BCM, TCM, ME7, MSA15.8, EDC16, ETM, DEM P2 Year models since 2005+ (SVXC70, S60, S80 etc..) You most likely are required change the setting of "CAN Bus year" to "2005 up" to get connection on supported modules. Main features: +Service Light (SRI) reset/programming +Fault Code (DTC) Read & Clear +Live (real time sensor data) +Read info of the system (ex. part numbers of ECUs and configurations) +Many Advanced commands like Injector testing (Motronic M4.4), TDi Fuel pump Dynamic Timing (MSA15.7), VGLA Remote Programming (fully now without dealership!) etc.. SRS light? It will turn off if there is no fault codes left. Capable of: -Program and adjust modules parameters via Service >> Advanced commands. -Read some basic standard OBDII stuff via Scan(P0* -codes, MIL light status, Supported PIDs - refer for Live).

What 850 OBD-II Is Used For

850 OBD-II appears to be a vehicle diagnostics app focused on selected Volvo models, especially P80-era cars and some later platforms based on the metadata. It is meant to work with an ELM327 Bluetooth, Wi‑Fi, or USB dongle to connect to supported vehicle systems, read fault codes, view live sensor data, and access system information such as module details and configurations.

The app also appears to support more advanced service tasks than basic OBD-II readers, including service light resets and certain module adjustments or programming functions. Based on the listed permissions, it may need network, Bluetooth, Wi‑Fi, USB storage, and sleep-related access to communicate with an adapter, manage data, and keep a diagnostic session active. This suggests it is intended for hands-on car maintenance, troubleshooting, and model-specific diagnostics rather than general driving use.

Common uses

Read and clear diagnostic trouble codes
View live sensor and module data
Reset service lights on supported vehicles
Access system information like ECU part numbers
Use with ELM327 Bluetooth, Wi‑Fi, or USB adapters
Perform selected advanced Volvo-specific commands
Support troubleshooting for compatible Volvo models
