larryh Posted May 22, 2015 at 12:24 PM Report Share Posted May 22, 2015 at 12:24 PM FORScan has released a new Windows version of their software that now properly reads all the modules available on the various CAN buses using an OBD II scanner: HS, HS2, HS3, and MS CAN buses. The organization of the modules is as follows: HS CAN SOBDMC - Secondary OBD Control Module CBECM - Battery Energy Control ModuleSOBDM - Secondary OBD Control Module APCM - Powertrain Control ModuleOBDII - On Board Diagnostic IIAPIM - Accessory Protocol Interface ModuleACCM - Air Conditioning Control ModuleGFM - Generic Function ModuleDCDC - DC to DC Converter Control ModulePAM - Parking Aid ModuleBdyCM - Body Control Module HS2 CAN OCS - Occupant Classification System ModuleABS - Anti-Lock Brake / Traction Control ModuleRCM - Restraint Control ModulePSCM - Power Steering Control ModuleSCCM - Steering Column Control ModuleGWM - Gateway Module AIPMA - Image Processing Module A HS3 CAN DACMC - Digital Audio Control Module CDSP - (Audio) Digital Signal Processing ModuleTCU - Telematic Control Unit ModuleACM - Audio Control ModuleIPC - Instrument Panel Control Module MS CAN SODR - Side Obstacle Detection Control Module - RightSODL - Side Obstacle Detection Control Module - LeftFCIM - Front Controls Interface ModuleRTM - Radio Transceiver ModulePDM - Passengers Door Control UnitDDM - Drivers Door ModuleGPSM - Global Positioning System ModuleDSM - Driver's Seat Module Hybridbear 1 Quote Link to comment Share on other sites More sharing options...
larryh Posted May 22, 2015 at 01:25 PM Author Report Share Posted May 22, 2015 at 01:25 PM It looks like they also added a new set of control PIDs. I wonder what they are for. Are they used to control various settings in the modules? Is it really safe to be changing the settings in the car? Should one be setting the fan speed for the HVB or turning various pumps on and off? Quote Link to comment Share on other sites More sharing options...
jdbob Posted May 22, 2015 at 10:27 PM Report Share Posted May 22, 2015 at 10:27 PM Is that the 2.2.4 beta? I tried just to see if they corrected the units for BAT_TO_EMPTY_ESTIM which is supposed to be Watt hours instead of watts. It wasn't, reported it again, we'll see if they actually do.

larryh Posted May 22, 2015 at 10:44 PM Author Report Share Posted May 22, 2015 at 10:44 PM (edited) Yes-it is the 2.2.4 beta. The Android and iOS versions are still using the old 2.2.3 kernel. So you have to run the Windows version. Edited May 22, 2015 at 10:55 PM by larryh Quote Link to comment Share on other sites More sharing options...
larryh Posted May 22, 2015 at 11:34 PM Author Report Share Posted May 22, 2015 at 11:34 PM (edited) FORScan does indeed allow you to control the car. I tried the BdyCM PIDs to lock and unlock all the doors. They did lock and unlock the doors. I don't think I will experiment with the control PIDs. You might damage the car. Setting the generator voltage, disabling fuel injectors, setting pump speeds, setting the spark advance or the camshaft angle, etc. is probably not the best thing to be experimenting with.

Russael Posted May 23, 2015 at 12:03 AM Report Share Posted May 23, 2015 at 12:03 AM I wonder if it is crazy enough to change the combustion cycle from Atkinson to Ottoman...? :) Quote Link to comment Share on other sites More sharing options...

There was a question about that on their forum earlier this year http://forscan.org/forum/viewtopic.php?f=6&t=991 Quote Link to comment Share on other sites More sharing options...
larryh Posted June 8, 2015 at 03:31 PM Author Report Share Posted June 8, 2015 at 03:31 PM (edited) I would not advise anyone to use a WiFi OBD II scanner. They are not secure. Anyone could use Forscan or another application to obtain the codes to unlock the doors or send the appropriate commands to unlock the doors and start the car, or worse, send commands that will interfere with the cars operation while you are driving. If you use a WiFi adapter, remove it from the car when not in use. A Bluetooth scanner is more secure. Forscan has the ability to change the codes to start the car and reprogram keys.

No choice if using Apple mobile devices. I think it's only the Windows versions of Forscan that can send commands. I suppose there's a chance that people are riding around in their cars with their laptop looking for WiFi OBD networks to interfere with, but seems unlikely. I think most people use their OBD to look for problems at home rather than logging data for analysis like you do. Quote Link to comment Share on other sites More sharing options...
larryh Posted June 8, 2015 at 08:10 PM Author Report Share Posted June 8, 2015 at 08:10 PM (edited) People should be aware of the vulnerabilities of OBD II Scanners. I'm sure a determined hacker can also connect to a Bluetooth scanner, but it will take more effort. Some of the cheaper ones constant broadcast their presence and have easy to guess 4 digit PINs such as 1-2-3-4. It is probably inadvisable to leave the car in a public parking lot with such a scanner still plugged in. ForScan and other applications make it easy for intruders to take control of the car. Some of the more expensive WiFi adapters might let you establish a secure connection. Edited June 8, 2015 at 09:58 PM by larryh Quote Link to comment Share on other sites More sharing options...
