Have been working with
@Jimmy07 offline to add the rear-view digital mirror to my MY23 RAM 2500 Rebel, and we're out of ideas. Installed the mirror 3+ months ago and it's always worked great. Went to finally go change the code with AlfaOBD and now have a silly erroneous error message that I can't get rid of.
Digital Rearview Mirror Unavailable Service Required
Went to change the 2 lines of code after adding my rear-view digital mirror.
CBC Config I/O Usage: RVDM Present: No to Yes
LIN & Misc: CRVMM Present: Yes to No
Soon as I make the change, I get this silly error message which briefly comes up upon initial startup. (No CEL, though.) Everything works, (RVDM has always worked since I installed it) and I now have the exterior auto-dimming rear-view mirrors restored with the code changes. Tried reverting the changes back to the original states and the silly error message remains. Coding is not supposed to work like that!
Added RVDM 68519222AA and the CHMSL with the extra camera 68465998AA. Dropped the headliner from the back just a tad so I could run a 10' Fakra cable. Has been working great for 3+ months, no problems. Only problem now is the erroneous error message.
Have to take it to the dealer for the SCCM recall, not sure what they will do with the error message.
