On-Board Scales... Need a bit of Assistance

[oneinch]

Thanks. I'm checking this out now.

Edit: Without actually trying this, I'm not convinced this will work for CCD suspension. It might. The Raptor isn't CCD, nor does it have the scale or smart hitch. Still, this is more information than I've ever read before.

We have the same system, just the signals from the suspension deflection indicators are used for different purposes

Truck came with the on-board scale system. Not sure if this belongs here or the general F150 topic but...

I get the idea of the system but it seems a little complicated to understand to me when I start digging into it.

1) Do you have to calibrate it at all? My payload from factory is 1680lbs. Is the scale system already set to that payload?

2) Is there any way to recalibrate it? Or do I need to recalibrate it? For example, I added a bed rug and tonneau cover. I think its about 100lbs worth of stuff. So do I need to adjust anything in the system to account for this or does the system already show weight added to the truck even when "empty"?

3) Pretty sure it doesn't include my 200lb rear-end, is that right? So if I'm sitting in the truck is that another 200lbs taken off of the scale? Already accounted for in the system?

4) How does it work with fuel burn and refueling? Will the scales show more payload capacity on 1/4 tank vs full tank? Do I run the risk, if not paying attention, that I could load to capacity... then go fill up the truck, and now I'm overweight?

5) I don't know how accurate payload is from factory but is there any value in going to official scales with my bedrug and tonneau, getting my butt outta the truck, full tank of gas, weighing the truck, and then subtracting from the GVWR and that is my remaining payload? Then can that be programmed into the scale system?

It seems like a handy feature, and I'm not a tech dummy, but for whatever reason I'm having a hard time wrapping my brain around how to use this thing in a fairly accurate/reliable manner. Not just for payload but I'd like to also use it for tongue weight in the near future.

I have a 2022 150PB 7.2 with onboard scales and CCD. When the truck arrived, this was not correctly calibrated and showed over 400 pounds in the truck when there was nothing in it, finally had to be recalibrated at the dealership before I had any, knowledge of forscan which is very recent.
If you’re contemplating any calibration yourself at the dealership, you will need to get the truck back as close to stock as possible. This would mean removing anything that was not in the truck when it was shipped from the factory from floor mats to tonneau covers and anything you have added to the cabin or bed. It may not be possible to remove things like spray-in bedliners so you will have to do the best you can. Payload is payload and does not include a driver. When you do the recalibration, nobody should be in the sitting in the truck.
Payload is GVWR minus curb weight. Curb weight is all fluids necessary to run the truck, including a full tank of gas and no driver. This is where you can cheat your truck back to stock weight. If there are things added to the truck of known weight that you cannot remove, simply calculate how many gallons of gas to leave the truck short of full, a gallon of gas weighing about 6 pounds.

After the recalibration, your payload should still be written at the top of the scale and the scale should be completely gray with no green bar. Sitting into the truck. your 200 pound rear end should add approximately 200 pounds of green bar to the bottom of that scale on the stack screen. And yes, technically you can increase the payload of the truck by driving it with half a tank of gas only ?
One final word. the onboard scale depends on deflection of the rear shocks and I’m not sure how accurate it is to be honest. I’m not sure that Ford has defined that either so good luck.

I attempted the recalibration tonight. I was not successful. I was able to read the live PID info and I believe the results to be correct. (I didn't take a picture, but I'll be trying again and will do so.)

I ran into problems executing the recalibration. It kept getting interrupted because conditions weren't being met. I moved the truck to another spot I thought was level. I used the off road page to get everything to ZERO. Only once did it complete the calibration. It did not ask me about fuel level. I checked the live PIDs and they were the same. Nothing seemed to get reset.

I'm disappointed, but not surprised. The procedure I was following was written for a Raptor. The Raptor doesn't have CCD suspension. I have to believe re-zeroing the CCD is possible, how to do it is still a mystery to me.

Edit: What I was trying to do was reset my on board scales. Because I lowered my truck 1.5" in the rear, the truck interpreted this as an overloaded condition and my scale was solid red.

Well, my scale is now green but the truck is telling me the scales are not operational. Go see my Ford dealer. That's not happening.

So, the recalibration did something. Not exactly what I wanted, nor do I know exactly what it did. I'm still in the same place I was, just in a different boat. My scales don't work. I don't use them, but I'd like them to work. If not, well, I like the lowered rear better.

what conditions should be met to run calibration?

my scales were not correct - always red.
I tried to calibrate it:
VDM Ride Height Calibration - works, but does not change anything.

Then I tried these options, but none of these works - I keep getting message "the vehicle conditions not met":

On-Board Scales - Height Sensor Calibration
On-Board Scales - Spring Calibration
On-Board Scales - Vehicle Payload Update

Then I found that my truck has CCD rear suspension, so I tried to follow instructions for Raptor, by entering ET mode. I can enter ET mode in neutral, but still these three options don`t work.
after many attempts my scales are no longer working "scales are not operational".
so now its even worse than it was =)))

OK, yeah you guys are kinda discussing one of my questions from my original post.

When I got the truck I did not check to see if the on-board scale was at "0" from the factory (full tank of gas, no passengers, no additional cargo of any sort, etc). I was looking at it the other day and with me in the truck (about 200lbs), my BAK X4s, a BedRug, plus some straps, gym clothes etc, I recall thinking that the bar on the on-board scales seemed to be eating up more capacity than I'd expect.

I suppose that's why resetting it seemed to make some sense despite not fully understanding the system. My BedRug after a quick search is probably 20lbs. The rolling tonneau is about 80. So there's 100lbs there off payload. I know that's not a lot but for the sake of this discussion what I'd like to do basically is take everything out of the truck other than the bedrug and the tonneau cover, fill it up with a full tank of gas, then set that scale to 0. Then either have my payload on the screen reduced by the 100lbs or leave my payload at 1680lbs but show the bar on the screen with about 100lbs of payload already on the truck.

I'll see if I can get a photo. But if people are estimating the screen is showing 400lbs of payload used with nobody in the truck or nothing in the bed or cab, that seems pretty inaccurate.

I'm not expecting perfection here or anything but if I can get within 100lbs or so I think that's useful. Especially as I'm assuming this same system also measures the tongue weight from my trailer and making sure that is balanced correctly is definitely helpful.

I can recall a procedure I ran in FDRS last year. I believe it was called onboard scales calibration. After running it, it dropped my scales to a more accurate payload.

Like many have mentioned, their scales were showing hundreds of pounds over on their scales in a stock truck without sitting in it. My guess is the Ford tech ran the calibration while in the truck.

My scales now shows a small green bar, taking into account the weight of my Talon skid plate and tonneau cover. I was not in the truck during calibration so this shows the truck is smart enough to talk to FDRS that there is additional weight over the curb weight.

If you have access to FDRS, give that procedure a try without being in the truck. Hopefully your scales will be more accurate after running it.
