Plz forgive me since i didnt scrub the thread. I just bought alfa obd. I have a 2013 ram 1500. If i want to copy all the setting from the current bcm and apply rhm to a replacement bcm ? I possess that is the same part number. There is a command under active diagnostics that says "backup vehicle config to file and restore vehicle config to file" Does this backup or/and write all the settings from the original? Is that all i need to use aside from the VIN write feature? I have attached a photo.

Here are some notes I made for swapping BCMs (note this is using the Android Version so be mindful that some steps won't be accurate for a windows user).
Notes for the BCM Swap
1. Create an AlfaOBD Backup of your current BCM Config (Body Computer -> Body Computer My2014 Powernet -> Car WIth Hood Open Icon - > Select Procedure to start -> Backup Vehicle Configuration to File)
2. When Complete go to the Hammer and Wrench Icon in the top right of the app and select Upload to Google Drive (At this point use the sign-in button at the top of the screen if not already signed into your g-drive).
3. Select Upload Any AlfaOBD File -> BCM Config -> ConfigBackup(Todays date and time)
4. When Complete Go to your G-drive and and rename the file with "2014" at the beginning as you will be repeating this process later for the new BCM. You may also want to create a new folder and place all of the files you are going to create for this now.
5. Read the System ID and Status of your current BCM Config (Body Computer -> Body Computer My2014 Powernet -> Battery Icon - > Read System ID AND THEN Read System Status. This will create a readable/printable log of all your current setting selections not in Hex format but in English
6. When Complete go to the Hammer and Wrench Icon in the top right of the app and select Upload to Google Drive (At this point use the sign-in button at the top of the screen if not already signed into your g-drive).
7. Select Upload Any AlfaOBD File -> Faults and Status Log -> Body_Chrysler_Info
8. When Complete Go to your G-drive and and rename the file with "2014" at the beginning as you will be repeating this process later for the new BCM. Place the File in the folder you created if you did not save directly to that folder when prompted.
9. Take a look at both of the files you created but do not make any changes as that will corrupt the files. You should see a bunch of numerical codes in the BCM Config and a series of options programmed in the Body_Chrysler_Info File.
10. Proceed to remove the 2014 BCM from your truck (do this all with the negative battery cable disconnected and isolated from the negative battery stud). Start by unlocking/removing the connectors (there is a black plastic retainer in the middle you can pull out to move the wire harness as far out of the way as you can manage).
11. Remove the 4 (13mm?) bolts securing the BCM to the firewall. The top bolts are more easily accessed by removing the driver side dash tweeter (I use a plastic trim tool to remove the grille and I think they are 7mm screws). Once removed you will be able to access the two bolts at the top of the BCM (but it's still a tight space to work in.
12. There are 3 (13mm?) bolts holding the parking brake on, remove them. Once removed you can lay the parking brake down on the floor to get space to remove the BCM and install the new.
13. At this point, consider weather or not you need more space to get the BCM out by removing the factory Alpine Amp in this area. It will be a black ribbed module locate (somewhere) in this area.
14. Remove the BCM from the studs on the firewall and cuss and curse it out of it's mounting location.
15. Optional - compare the pins on the old and new BCMs (I took pictures, there was one difference on one of the connectors, I'm interested to know if you see similar)
16. Reverse steps 10-14 to install the new BCM.
17. When all Connectors are attached back to the BCM and locked in place, reconnect the Battery cable
18. Before uploading your old config, repeat steps 1-9 for the new BCM ensuring you rename the files with "2016" to identify them correctly.
19. DO NOT Turn on the ENGINE (insert the key to RUN but don't crank) To program the new BCM, you will need to Restore an AlfaOBD Backup of your current BCM Config (Body Computer -> Body Computer My2016 Powernet -> Car WIth Hood Open Icon - > Select Procedure to start -> Restore Vehicle Configuration from File). Ensure you use the 2014 file first created (BCMConfig*Todays Date*) . I can't remember but I think it will use the file directly on your phone instead of prompting you to choose a location on your G-Drive, just match the timestamp to the first backup you created for your 2014 BCM (this will be the hex format file).
20. If successful, it may be beneficial to remove the negative battery cable again for 15 minutes or so. This will reset all of the modules connected to the BCM that may have read information from the new BCM before restoring the old configuration.
21. Reconnect the negative battery cable and start the truck. Record any faults stored by reading them to the log file. It's important to note, that the log file(s) are continuos so instead of a seperate file for each it will have a running list of what you have requested. You'll need to manually segment the sections in a text editor if you want to organize it better.
