This app is mainly for P80 Volvos of years 1996-00 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. Now even some P2 functionality! 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 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 These has still lot of work to be correct. C70/S70/V70/XC70, S90/V90 series Mostly all has OBDII support except Fenix 5.2 ECM. P80 Year models from 1999-2000 All modules covered? CDM, ABS, TCM, ECM, ECC, VGLA (Remote program!).. etc. P2 Year models since 2001+ (and 1998+ S80) CEM, ABS/BCM, TCM, ME7, MSA15.8, ETM Can be read limited ways. P2 Year models since 2005+ (SVXC70, S60, S80 etc..) In App Settings menu you most likely are required change the setting of "CAN Bus year" from "1999 to 2004" to next "2005 up" to get connection on supported modules. Main features: +Service Light (SRI) reset/programming +Fault Code (DTC) Read & Clear +Live (realtime sensor data) +Read info of the system (ex. part numbers of ECUs and configurations) +Injector testing (Motronic M4.4) +TDi Fuel pump Dynamic Timing (MSA15.7) +VGLA Remote Programming (if you have PIN code) -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). Live (scrolling values): +COMBI +ABS +SRS (airbag) +Instrument panel (COMBI) +AW 50-42 / AW 30-43 (Automatic Gearbox) +MSA15.7 +Motronic 4.4 +Immobilizer +ECC -Read and translate most Volvo specific DTC:s. *Fault Codes supported fully from: +MSA15.7 (only with D5252T engines!) +AW 50-42 / AW 30-43 +COMBI +VGLA +912-D Heater +ROP (Roll Over Protection) (only C70?) +ECC (only S40/V40, C70/S70/V70/XC70) +IMMO +EMS2000 +RTI +Powerseats +SRS (1996-2000 models) Component test (Activation): +Motronic (M4.4) -Injectors -Engine Cooling Fans -IAC Valve -Fuel Pump Relay ... Please refer website information as its most updated! -You can use this App too as a terminal for ELM327 to send individual hand written commands at Service screen for what ever you want and supports multiple command sent at once. Please read ( i ) - button to check how in app . ============== There will be some errors/bugs as i can test things mostly on my own Volvo and or bench. So when you send that log 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 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.
