My dad has this van and it has low tire warning for the two rear tires.
All 4 tires and spare are set at 50.
It calls for 80 on the rears, so it’s constantly showing “low pressure add air” For the rears only.
I can’t find any info in the owners manual about acknowledging the warning.
Any ideas?
 
Duh.... I re read the title :doah:
 
If they are lower than it calls for that light will stay on and you can't do much about it really. It'll just come back.
 
If you set them all to what the door plate says it'll still take a few days or more for it to shut off. Probably ride like a wood wagon though
 
The truck that I have at work specifies 80 for the rear tires, and I believe that I have them at 70 since it doesn't have that much weight on it. I believe that the warning comes on around 66 psi on it. It's an '07. It seems to be doing fine as far as tire wear, but it could ride better a little better.
So if you don't want to try more pressure, then the only trick that I know of is removing the sensors, make a tube out of PVC pipe and parts, put a Schrader valve in one end. Then put the sensors in this, put enough pressure in it to shut the light off, and store it under the seat. Air it up once in a while if the light comes on...

Probably not the "help" that you are looking for.
:D
 
I've read about people putting the sensors in a pipe of sorts that can be pressurized to the correct setting to keep the alert turned off.
 
So really no way to run a decent daily pressure (45-50) without the warning being there.
Good thinking GM...WTF?
 
Nope. My dodge is like that too. Luckily it has a “light load” button that allows you to run the tests at 45. Makes a big difference when it wants 70 on standard mode

My understanding is per the government, TPMS, back up cameras and sensors are all mandatory equipment in new vehicles

Definitely not the cameras and sensors , you can still get brand new rigs with out those . But I think even the 3500’s now come with TPMS

Cameras have been required for a couple years now. Not sure which class of vehicle exactly, but they are required. Parts are so cheap now, if it saves a couple people from running over their kids, its not a bad move.

Not to be contrary, ok, to be contrary, "On March 31, 2014, four years past its deadline, the U.S. National Highway Traffic Safety Administration announced that it would require all automobiles sold in the United States built beginning in May 2018 to include backup cameras." https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=2ahUKEwi3iaGenZ_iAhWoxlQKHQQXB0oQFjACegQIDhAK&url=https://en.wikipedia.org/wiki/Backup_camera&usg=AOvVaw04Agkj-tmivulKhy77ap5r

Can we blame Ferd with the exploder that ran the Firestone tires low on pressure?
So now there has to be another safeguard to prevent more lawsuits..

Yep, we can thank Ford and Firestone for this heeping pile of scat to deal with on every vehicle. Only 3500 duallys from GM don't have tire pressure monitoring.

On the 17's though, even at the dealership I can't alter the settings for a more compliant ride. The programming is based on the VIN/option content. If it's a 3/4 or 1 ton, it's 55 up front and 80 in the rear. They have to base the pressure on the assumption that the unit is going to be run at max capacity. Running too low when loaded to the max will cause a blowout and in GM's eye's (and every other OEM too) makes them ripe for a lawsuit they can't win. So due to a few rotten apples the bunch gets spoiled and we all get the joys of tire pressure monitoring.

The module responsible for the tires differs from one model line to the next. Most use the remote control door lock receiver, where some use the Body Control Module. What I don't know is if the EFI Live or HP tuner's has the ability to get into secondary modules like the RCDLR or BCM.

Up to 2012 we could make a change to the pressure ranges for the tire monitoring. We could also change the tire sizes as long as the tire size we were changing to was something sold on any GM vehicle. We did change more than a few to the 315/70r17 size (factory H2 Hummer size) for guys running that size tire on Silverados/Sierras. But when the 2013 Model year came out, which was the first year the GDS diagnostic system phased in to replace the Tech2 the ability to change TPMS pressure values and tire sizes stopped completely. After that the only way I could change the tire size is if the customer bought an accessory upsized wheel/tire package, like going from factory 20's to 22's. The wheel/tire package came with a code we call into GM with the VIN, they alter the spec and we reprogram the module with the new calibration file. They will not alter tire psi specs though. I've tried.

So it may be required on cars and suvs it’s definitely not required on 1-tons.

I’m in the market for a new truck , I’m going back and forth between a Ram and Ford SRW 1-ton. Back-up cameras and parking proximity sensors are NOT standard they are optional.
 
Yeah, I wondered about "automobiles" vs something like "all cars and trucks". When a truck cost 80k+, guess the manufacturers need a way to squeeze a bit more out on options lol
