2021 night edition third brake light

[vincentw56]

well i got the BCM back from the guy who was going to program it and while he did get it out of plant mode he didn't set the VIN so the system won't let me cycle the key.

i won't have the truck long enough to keep trying because insurance is taking it soon. i'll have the mirror, cable, chmsl and BCM for sale if anyone wants to buy the lot and try.
i will not when doing the alpha obd command to acc/run1 the mirror lit up and said to flip but didn't have the broken linbus symbol.

i'd like $800 for the set (paid $1100+shipping/programming that didn't work); cable, mirror, chmsl, 2021 bcm. all brand new and never driven, only installed loose to test.

Sold to vinventw56

I hope this gets solved, sorry i wasn't able to be the one to do it.

I need to figure out how to get my VIN in the BCM. And then I can start working on it.

the dealership should be able to do it but you will have to have them install it.

Does anyone know why there appears to be 2 PNs for the digital mirror?

I know 68448641AB is the one we have been referencing in this thread. Just wondering if this other PN could have different wiring or features that may help with issues.

 

[vincentw56]

I have an appointment on the 29th to get the TSB done for the A/C so they are going to add the VIN to the BCM then.

BTW, it appears you can now build a 2021 Rebel with the Technology package w/o the Advanced Safety Group package. I have also seen 3 on dealer lots configured this way. Is this possible because they don't have auto diming side mirrors or auto high beams? It does say that the digital mirror is auto dimming...

 

[nandalora]

Can anyone confirm that the only dimming function that you lose is with the side mirrors? And why is that? (I have a Laramie w/o advanced safety)

Just want to make sure the dash and IP will still dim as normal. Thanks

Random idea, could the fuses for the mirror be different between the 19/20 and the 21 that could be causing the issues? Just crossed my mind so no idea if it is it

 

[vincentw56]

All right all, they put in the 2021 BCM into my 2020 and they did it won't take a program. I'm not sure why, but maybe there's a change between the years. @Jimmy07 any ideas?

I’m guessing they installed it and tried to restore the vehicle configuration to the new bcm?
On another note, new AlfaOBD android version today. I haven’t checked if there is one for windows yet, but with the windows version, you would connect to the bcm, switch to advanced mode, select MY2021 powernet. Find the setting radio & connectivity: digital rear view camera present, and set it to yes. Hopefully that does it.

Edit above- update is available for windows version of AlfaOBD. Anyone with the windows version and a 2019-2020 truck with the digital rear view mirror and camera installed, try the setting mentioned above in the 2021 settings list.
Edit again- sorry guys, that is not the correct setting. I’ll keep looking through the new lists.

I'd be more than happy to connect to my 21... tomorrow. Lol sorry guys just got off work and it's another early start tomorrow. Anything in particular you want me to go after?

If you could pull your BCM system ID again and send it to me, that’d be awesome. I can re-compare to some others.

 

[vincentw56]

I don't know if they were even able to set the VIN. They said the truck wouldn't start with the new BCM.

Anyone by chance figure out how to get the auto-dim feature for the mirrors to work after installing the digital mirror and CHMSL w/ camera. I bought the CHMSL w/ camera but haven't purchased the digital mirror as I am not willing to loose the auto-dimming mirrors.

 

[Mr. Chow]

I think I am going to attempt to bring the camera into the 12in display. 1st attempt will be using a connector / convertor like
https://www.etrailer.com/Accessories-and-Parts/Quest-Audio-Video/292-101408.html?msclkid=e8e754a57c5917c8649d342a34f5e094&utm_source=bing&utm_medium=cpc&utm_campaign=Bing | Dynamic - Search Ads&utm_term=/accessories-and-parts/&utm_content=Dynamic - Accessories and Parts
And utilize the pins 21/22 and enable the cargo camera
If anyone knows of a convertor that would be better. I am expecting these cameras to be digital and PIN 21/22 need analog. So I am expecting just a cable conversion to fail.

Ill use the following post for guidance.

Cargo Cam input - Car PC/Telemetry project.

When I was a kid I was promised a computer in my car, with a live display and it would be... useful. Now I have the display and it is time to get this computer jamming. the long term goal is to have a working PC in the truck that can pull telemetry data from the CAN or OBD2 and respond to...

If all fails Ill order an analog camera and swap them

@Jimmy07 Do you think that it could be just setting we are missing, or do you still think we need the 2021+ BCM? I have all the parts, but the dealer couldn't program the BCM. Is there anything you can do? I would be willing to send you all the pieces.

Ok, got my mirror and camera installed today...good news, bad news time...

Good news - the mirror and camera works, also I found that the mirror, in camera mode, does dim the image as needed when the light sensor is covered.

Bad news - I lost many settings in the UConnect screen! Please see details in my thread. Is this just a coincidence of resetting the battery or could the mirror install cause this??

Help! Lost settings after battery reset

So, I removed the negative battery terminal to remove the factory auto-dim mirror and replace with the video rear view mirror and 3rd brake light camera. This could be a total coincidence but when I reconnected the battery and started the truck I have lost many setting including - driver...
