Hi hoping someone can help out here, I've looked through the forums but didn't see anything helpful so apologies if I missed something already here.

I have a 2014 volt and I have had it 2.5 years now. The backup camera just stopped working, it's now just a black screen when I put in Reverse (it has the yellow warning icon in lower left). All the sensors still work and I also notice that the backup light doesn't come on now either.

Not that it would be the cause but a bird decided to dump his month of poo on my window, so I sprayed just the front of the car off. It was working 5 minutes prior to this, and didn't work after.

On the Display, if I navigate to Config / Display Settings / Rear Camera it doesn't have the camera there at all so to me it means it's not getting power.

I've been looking through the manual and other forums to see if there is a specific fuse for this but I don't see one, does anyone know? I've pulled the negative off the 12V battery as well hoping that resets the system, not sure if there is another/better way to do so.

I took the volt into the dealer but they said they will not cover this and I have to pay $175 to have it looked at, considering its a lease and I have 6 months left I passed on it. Hopefully they don't try to charge me for something I didn't break!

Are you still under your bumper to bumper warranty? If so, it should be covered no matter what. Putting water on the front windshield has no contribution to what has happened unless something was wrong to begin with.

 

[stoney66]

Yeah the water was just a coincidence, just thought I'd mention it

The dealer told me that the camera isn't covered since I am over the 36,000 mileage (I'm at 39,000).

You may want to see if you can get a Volt advisor involved. You are not that far out of warranty for some good will.

Aside from that, I would certainly suspect either a blown fuse or a broken or shorted wire leading to the backup lamp and camera. Maybe WOT will jump in on how to diagnose this.

 

[stoney66]

Thanks Scott. I am hoping for blown fuse, just none are labeled for this specific thing and if it's shared I don't see anything else that isn't working. Too many to go through and they are a bit hard to tell on some if they are good or not.

Instrument Panel Fuse Block (Right Side) -----> F7

This is for: Body Control Module 6/Map Lights/Courtesy Lights/Back–up Lamp. Start there.

 

[stoney66]

Mister Dave that was it. Just replaced the 7.5a fuse and all good. I didn't notice that the courtesy lights above the dash were not working either (never use em). When it popped the fuse in one of them came on.

Glad to help.

 

[stoney66]

So the fuse popped again today. Guessing short somewhere.

If possible, can someone verify if their fuse for F7 on the right panel is 7.5A?

 

[stoney66]

anyone on the fuse size?

 

[cueballsi]

did oyu ever find out where the short was??

 

[stoney66]

never did. Already turned the car in as it was a lease

Bringing up an old thread here, but I'm having the exact same issue.
Backup camera stopped working, and the reverse light was stuck on. It was just at the dealer for reprogramming, so I thought they may have messed something up. They checked the BCM programming and all was good, then found the bad fuse. Replaced it, and it blew right away.
Since it was easy, the tech unplugged the camera, and the fuse now works, and the backup light works correctly again. So it appears the camera is shorted internally.
Anyone know where I can get a good price, and details on how to replace it?

GM Part 22883286 is about a hundred bucks many places online. How much better do you need? There's a thread with many pictures here: https://gm-volt.com/forum/showthrea...Rear-bumper-removal-and-updated-camer-install

Well I replaced the camera last night, and while it's no longer blowing the fuse, it still isn't giving me any picture. I just get a black screen with the guidelines.
Any other suggestions? I'm assuming there must be a bad connection in one of the video wires, but I have no idea where it could be.

Disconnect the camera and ohm out the pair of wires that carry video signal, if resistance is an open you have a bad connection wire somewhere from camera connection to where it terminates into the factory radio. Did you also confirm 12V and ground is getting to the camera?

 

[jbakerjonathan]

Is it possible to reverse the wires inadvertently, or is the plug polarized? I haven't looked at a schematic or seen any photos of the cabling.

That's tricky because the plug on the car end is the female plug. I would need to find some tiny probes to put into the openings. The pins are probably less than 1/32" wide. Or I'll have to cut back the loom, and pierce the insulation of the wires.

The plug is polarized, so there is no way to reverse it. I originally got an aftermarket camera by Dorman and thought maybe it was wired differently at first. But then I picked up an OEM unit from GM, and got the same result.

Perhaps unbending a couple of small paper clips and inserting them into the female socket would allow you to easily measure the resistance to ground, etc..

2014 Volt - went to autozone - out of 7.5amp fuses - bought a 5 pack of 10amp fuses - "temporary OK" according to the AZ guy

replaced the F7 blown fuse with the 10 amp in the parking lot - backup camera and dome lights work!

by the time I get home F7 is gone again

replaced it again from the 5 pack of 10amp fuses

Lasts another 2-3 trips - blown again

any chance this is still covered under warranty?

thanks
