This issue with the 2021's is solved......sort of. Ford needs to change the brake controller module to a revised one, then reprogram the ECM and BCM. I say sort of because now the issue is Ford does not have the revised module and has no idea when they will have them available due to the chip shortage. They will probably make this low priority for trucks already sold when they can't get new trucks to market because of lack of hardware. They'll drag their butts and devote anything they can get to new sales until when this fiasco eases. One thing is certain and that is this chip thing won't be resolved until 2022 or possibly even 2023.

On a side note GM has brake controller issues with some of the new Silverados where they will not put out more than 7 volts. Same deal here, parts to rectify are not available.

Not really a time to buy new trucks, or a lot of other things. Some of these clown dealers are tacking on a $5K "market surcharge" to new trucks and its non negotiable, sticker + $5K. Go ahead and walk, they don't care because another sucker will come along and pay it.

Measuring IBC output with a volt meter no longer works with most modern controllers as they are variable pulse width signals they put out and not an uniform straight line DC Voltage that is varied.

Your point is? I don't care how the output is measured or what is used, it's a known issue with some new Silverados and GM has a TSB issued about it, but not the parts to fix it. 7 volts does next to nothing to a brake magnet. I doubt you see many owners of a new Silverado affected out in the driveway with a pulse modulation refractor, a nuclear densmometer,and a schwansoculator trying to diagnose the factory brake controller on a new truck with a BtoB warranty lol. :S
