'Invisible' trailer camera calibration.

Maybe it's just me, but doesn't it seem like if you turn off your truck for something like fuel, that the camera system shouldn't have to recalibrate. I know the instructions say it has to do that, but seems to me that it really should add a feature to that says if the vehicle is turned off, then back on within a 30 minute period that it doesn't have to go through the calibration step all over again. 

 

I'm loving the camera on my Airstream, but I find it certainly takes a bit longer than 60 feet to get it calibrated and sometimes getting it calibrated before you have to go faster than 25 MPH is impossible. Anybody else feel that they should have some storage of these values? At a minimum I would think the way to do it is try the previous values and see if the previous values are still valid.

You should only need to calibrate once.  I'll ask around see if there are any issues that may cause this.   #iworkforGM

I’m new to this conversation, but going thru similar issues.  Mounted rear camera on the tail of my 30’ travel trailer yesterday, paying attention to getting it mounted on the sweet spot.  Entered all

Well, I got the first I heard of that.  As long as you select your trailer profile with the dimensions save in it, you should not have to recalibrate as long as you don't change a dimension or the cam

You should have to only calibrate once as long as your profile is saved with dimensions.  If you change any dimensions or a camera, then you will need to recalibrate.  The calibration distance depends on a lot factors.  I have calibrated around a 100 trucks and never seen one calibrate under 1000 ft.  Calibration does not like shadows in the camera view.

Interesting.... I know my dimensions are saved with my Airstream profile. I wonder why it wants to recalibrate all the time?  It does look great though. I know I read something about it having to recalibrate... I'll need to go find those instructions now.

Your picture looks like you got the dimensions correct.  If you still have problems, send me a picture of the camera on the trailer and I can see if anyone has a suggestion.

I have had it loose cailbration at fuel stops also, most of the time it figures itself out but not always. Other times I can pick the trailer up from storage and it recalibrates before i get out of the lot. I have been leaving the truck running during pit stops just to keep from loosing the calibration.

Interesting, @sdelam... that mirrors my experience. 

So I just looked at the box that came with my camera. 

Apparently the new part number is: 84946379

My camera part number is: 84876818

 

@MTU Alum: Can you tell me what has changed? Is there any updated firmware? Would the new camera behave differently?

Mine is older also, bought it last year and it was a 2019 1/2 ton part number.

I'm not sure of the difference between the two.  I know their was a change to the connector orientation between the 2019 and 2020.  I personally have only used the 2019 version.

Hello. I am hoping someone can help.

I installed my camera and entered dimensions. The view is satisfactory to me but my camera wont calibrate. I have even taken a 15 mile drive. The furthest progress bar has gotten is about 1/8 the way. Any help? Is there way to force calibrate since I am satisfied with the view?

 

Thank you

You have to be under 30 mph to calibrate and it only calibrates when you are in a relatively straight line.  Did you mount the camera in the recommended area?  Which is basically center of trailer 2 inches above your tailgate camera with trailer attached.

I am having the same issue.  Installed camera and mounted dead center of target area. Set all dimensions and started drive to calibrate. Nothing in the instructions say you have to drive less the 30mph. It only says drive forward for at least 60ft. I drove over 50 miles today and it still is not calibrated. Camera is functioning great and have all views except invisible trailer. Any help would be great.

It will only calibrate while going straight under 30 mph.  Find a place where you can drive at slow speed in a straight line.  It's ok to turnaround or make turns while calibrating.  The calibration can have issues if there are shadows in the camera view.  On sunny days, you can get shadows in the image.  Try going in a different direction.  I recommend selecting the transparent view during the calibration process.  There will be a yellow status bar at bottom of the view to see the progress as you drive.

Thanks for the reply. Yes, I found the side to side center line and mounted it about 2 inches about the height of the truck camera. I did do a long straight run for at least 1/2 mile at <30 and nothing. The calibrating finally times out and it does the transparent view.

Thx again for any assistance

      Tire psi

      By jgaudet99 · Posted

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      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.
