dash cam power issues

I wanted to see if anyone else has experienced problems with the t1xx generation where there is no 12v accessory outlet and you only have usb-c and usb 3.0 ports for 12v power. I have been having a problem lately with my vava 4k dash cam where the cameras internal battery dies out and it never was an issue before but I also had it where only 1 of my dozen USB-A to microUSB cables can work when connected to the dashboard mounted USB ports to power on the camera. If I use the factory microUSB cable or any other cable but the 1 magical cable, the camera will get power and turn on but locks itself up hard and won't function unless I plug the camera into the rear seat USB ports that are power only, I use a 120v to USB adapter in the center console to connect the camera to, or I use that magical microUSB cable that lets the camera charge and power on.

 

I ordered some usb-a data blocker adapters to try and see if that might help but for the last month my truck is somehow trying to pass data through to the dash cam all of a sudden. If the data blockers don't help my problem then I think I might just need to hard wire a 12v outlet so it can run off accessory power when needed and hope that is my fix to this madness.

 

My truck hasn't had any OTA updates for almost a year now (I still think that's strange that my radio is on the android security patch from February 2023, really makes me feel safe and secure without security updates to the radio and only the apps are updating on the radio) so that isn't something new that messed with the camera. Rebooting the radio or pulling the battery to the truck for a few hours doesn't help the issue.

 

Does anyone have any suggestions on something else I can try? How the dashboard is setup on the refresh models makes it unnecessarily hard to try and run a wire under the dash for power and ground and I also need to research where I can tap into the 12v accessory line. If I could snag some power from the fuse that is jumpered in the passenger side of the dash for the USB ports where you can select constant 12v power or ACC power only for it that would be easiest but i'm not too big of a fan of the fuse taps.

Following. On my 2019 I had my emergency light bar plugged in to the rear console "cigarette" lighter. My 2023 doesn't have that feature. I hate to, but it looks like I may have to figure out a hard wire fix.

Have you tried moving the block that connects to F27 so it connects to F28 instead?

I previously was on F28 and switched it to F27 since I don't need the camera recording 24x7 and have it drain my battery on the truck unnecessarily.

 

So far what might have done the trick is to use a USB data blocker in line with the USB that goes to the camera. Why in the world I have to use that all of a sudden is weird but it was a suggestion my boss gave me and it seems to be working. If by the end of this week the dash cam is still working then that was my fix because usually after 4 days of driving around the camera would freeze up and crash from a dead internal battery on it when I wasn't using the usb data blocker.

So update on the fuse in the instrument cluster at the passenger side. That circuit swap does nothing to the USB ports on the dashboard and only affects the USB's in the center console or at the back seat. IDK why GM had to make one set of USB's so they are always on retained accessory power only but you can control the other 2.

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?

      Tire psi

      By jgaudet99 · Posted

      That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?

      Would this CV Shaft be bad?

      By newdude · Posted

      That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?

      Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
