AlfaOBD

Even though the option and place to enter the numbers is there? I found posts with instructions on doing it on a 4th gen.

Correct. Alfaobd can’t do it on 2019+ HD Ram trucks.

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.

FYI - my truck (‘24 PW lvl2) has the RVDM from the factory, and when I put a topper on and installed a long fakra cable to move the camera back to the topper, I occasionally get this error message. I’m guessing something to do with the resistance of the longer cable may be triggering it - but it only mildly bothers me, and is very intermittent, so I haven’t dug in further. Not sure that’ll help, but it is a data point, and if there are solutions to test, I am happy to try them out! Can also provide a alfaOBD log file if anyone needs it!

Is there a way to make the led turn signals red?

I was behind a 23 or 24 today with the LED taillights and his blinkers were red, and I prefer that look.

It’s the physical tail lights themselves. For some odd reason, they got rid of the amber leds on the boards and went back to red. Then they REALLY went backwards with the 2025’s and went back to combined rear lighting.

What a seriously terrible decision. I'm sure it was cost savings. The NHTSA has been saying for years that amber turn signals are safer, and the EU has mandated them for a long time for the same reason.

Actually, try these settings, and it should mimic the red turn signals:
CBC Features: Combined Rear Lighting Enabled- Yes

CBC Features: Single Element Tail Lamp- Yes

CBC Config I/O: Connector E Pin 3/Connector F Pin 42: Rear Turn Lamps Output Present- No

CBC Config I/O Usage: Separated Lighting Brake Lamp Dropout- No

Thanks! I’ll give that a try.

You must figure this stuff out in your sleep. LOL

No dice. I didn’t have any rear turn signals when I tried.

quick one on max cruise setting... I'm changing it, but the "started, please wait" message doesn't clear, even though test staus advise its saved... this is the only change I've seen that doesn't give a confirmation message quickly...

@Jimmy07 is this available in JScan? I can’t find it.

I’ll double check some settings later. Trying to think if I missed any, it’s basically the opposite settings of what I did when I put the 2019+ tail lights in my 2017.

Are you checking in modules > Powertrain control > configuration

Yes, don’t see it.

My computer with AlfaOBD is at work, I’ll use it next week.

@Jimmy07 Is there a way to change alfaobd to display units in imperial freedom units?? Within the app when showing EGT temps for instance.

Anybody have any tips for making the odometer correction work? I had to swap my old 7" cluster in for some warranty work since the 12" cluster mileage can't be corrected yet. And I'm having some problems getting the odometer correction to take on my old 7" cluster.

I did it once before when I first did a cluster swap, but it wouldn't give me the exact mileage I was entering. Now it won't let me change the mileage at all.

I follow all the directions in the app, and when it says it's complete the cluster reboots, but the mileage doesn't change, even if I let it marinate for a couple hours.

Is there something I'm missing?

Edit/Update: I Got it to take by giving up following the directions and spamming the procedure. After running the procedure 2 or 3 times w/o turning the ignition off and doing all that bs it finally did change.

Has anyone changed he value for camera Brightness under Radio settings?

I haven't tried that, but I suspect that's the brightness adjustment on the camera image itself (like adjusting the brightness in a photo on your computer), not the backlight of the screen.

I was just wondering if it improves the back up cam at night etc...

Ahh ok. It might, I just assumed you were trying to lower the brightness of the screen when the backup camera comes on a t night. Lots of people have complained about that over the years.

Does anyone know how to code out “driver profiles”? It’s annoying as frick for the UConnect to reprogram itself if you use the 1 or 2 seat buttons (memory seat feature that ties into Uconnect5)

You could just set it to the same profile for both seat buttons.

You could also try changing this setting, but I'm not sure if it'll work. Under "Settings" on UConnect go to "Doors & Locks" and disable "Personal Settings Linked to Key Fob"
