B127B Rearview camera input signal circuit missing reference, 2014 GMC Sierra

[@scottkern435]

Glad I found your video. Just a little contact cleaner at the rear junction box and connector solved my issues. I was getting fuzzy picture when it would work, otherwise fuzzy gray picture with "Service rear vision system" message. Thank you! 2015 2500HD

[@pipcwp]

my camera just started doing the same thing this week on 15 silverado. Thanks for the info

[@DallasAutoDiag]

Good luck

[@Alexphutchison]

I replaced my camera too and still nothing. Did you find a fix?

[@pipcwp]

@@Alexphutchison not yet. I hate to do it but i think im gonna send it to the dealer.

[@pipcwp]

Mechanic I had look at it said it just lost communication with the camera. So I’m gonna try to figure it out for myself before I send it to the dealer

what is the problem with mine it use to beep when i get close to an object when backing up

[@El_LeChErO91]

Would this be the same problem and fix for a 2016 chevy equinox? The screen is black but can still see the guidelines and at rare moments we actually get a picture.

[@DallasAutoDiag]

I think its the same!

[@Synchrimedia]

thanks for the helpful video. i have a 2021 Chevy Colorado and the rear camera only works half the time. I either get good video, no video, or a mixed screen of blue and video (like the vertical hold on an old TV is off). It seems to do it more when the weather is bad, but it does it in nice weather too. had it into the dealer twice under warranty and both times they said they couldn't recreate the problem. so frustrating to deal with this all the time. I'll have to check my fuse block like yours and see if there's any evidence of corrosion. I checked the wiring at the camera and underneath the tailgate but they look fine. It takes a month to even get my car into the dealer's service department, then they don't bother troubleshooting it at all. very disappointed in GM service where i live!

[@DallasAutoDiag]

Hi, I don't think your issue is at the fuse box. Try to find a local tech so he check the wiring and see if there is any part exposed. That video signal wire that runs from the camera to the radio should be shielded in order to keep the outside electronics noise away from the video signal. Its either that or maybe your camera plug is getting some rain water mixed with dirt that would make a bad video signal. Good luck 👍

[@DonYaa-e7j]

What is did you change or clean the fuse box ?

[@MarkCoreyCopartAdventures]

Great video. My 2014 has the same issue. And the reverse lights aren't working. I've traced everything like you have. I'll try a new fuse box. Thanks for the information.

[@DallasAutoDiag]

good luck

[@MarkCoreyCopartAdventures]

Just finished installing a used underhood fuse box. Fixed the camera and reverse lights! Thanks again.

[@DallasAutoDiag]

@@MarkCoreyCopartAdventures glad it helped

[@franciscobotello4381]

What fuse is it?

[@vanbilly8387]

2016 Colorado; backup camera works, but a little fuzzy. It also isn't showing the guidelines at all. Figured it's time to replace the camera itself. Are the guidelines controlled by the camera, or is that a head unit thing?

[@juliomoreno5370]

2015 sierra any things I should check

[@DallasAutoDiag]

Everything

[@Hbn182]

Had this same problem today, just ordered a new fuse box..I opened it up and was almost the same as yours

[@DallasAutoDiag]

Good luck. Hopefully it fixes it.

[@7aMoODaiZER]

Can you help me ? I own a 2016 tahoe im facing a message that keeps popping up since 2018 “battery saver active” i changed the negative battery cable , changed the alternator and changed the battery still facing the same problem

[@7aMoODaiZER]

بتحكي عربي انقذني 😅

[@DallasAutoDiag]

Stop changing parts and let a good tech take a look at it

[@monsterkilla1982]

I'm not getting ground on 35 on the relay....if I jump ground to it it will click and camera will flash on then off...any recommendations?

[@hawkskyflier]

Great job!!!

[@DallasAutoDiag]

Thanks

[@raull8346]

Hey i am having the same problem do you think you could take a look at my truck?

[@DallasAutoDiag]

Yes contact us on Facebook

[@drewelrod7456]

My camera has had service rear vision for 2yrs after installing LED bulbs and after switching back to halogens it still says the same. I’ll have to give this a try and see if it helps.

[@DallasAutoDiag]

Hopefully it helps

[@eryk2483]

My back up camera for my 18 Silverado stays on at all time when the truck is running but it shuts off once i shut down the truck and have it on accessory mode Thats when i can actually use my radio go thru settings etc… any suggestions on what could be wrong with it? Anyone?

[@montelongopedro5]

Bro i have the exact thing going on right now, did you figure out what your problem was after all ?

[@smiley19912]

Nicely done, divide and conquer.

[@DallasAutoDiag]

Thanks

[@tonimunoz5150]

I just install a backup camera, but no image comes on. It just shows a blue screen anda the same message “ service rear vision system” Do you know what could it be?

[@Alexphutchison]

That’s what this whole video is about…

[@ClydeBoyProductions]

Man great job ! I’m having issues with mine dealership said I needed a new camera bought the camera installed it still nothing . I’ll check this out

[@DallasAutoDiag]

Same with this guy her replaced almost everything. Good luck man.

[@Alexphutchison]

I tried replacing the camera too and still nothing, did you find a fix?

[@bowmanoutdoors7989]

I think I’m having the same issue. Did you have to program this new fuse block to the truck? I’m told I have to.

[@DallasAutoDiag]

No programming needed

[@bowmanoutdoors7989]

Wow, ok. I wonder why Chevy said that. I heard that from the and the transmission shop. Do you think it would change for two years newer?

[@bowmanoutdoors7989]

You are the man!! I really appreciate you taking my call answering all my questions. I did the exact same thing as you did and it worked like a charm!!! Could not have figured this out without your video! Keep it up!!

[@TheReal_BigPK]

Mine blows the backup light fuses when it shows me that screen?!!! Anyone have that happen too>?

[@DallasAutoDiag]

A wiring is rubbing against the body

[@Throneroommusic7]

Very helpful video!!

[@DallasAutoDiag]

Thanks

[@cahg3871]
