How to shut off low tire pressure light?

[ColoMan]

I have a 2021 Ram 2500 with aftermarket rims and tires and run them at 45lbs unloaded. Can you disable low pressure light and stop the tire pressure screen from popping up every time I start the truck? I

thanks

With AlfaOBD and the security module bypass cable you can set the pressure where you want it. Plenty of info in the AlfaOBD thread.

Great info, thanks!

AEV procal snap also works.

Some have reported using the STFA presets to lower the TPIS threshold is sticky.

Can't say with certainty it works as I set mine with AlfaOBD.

2020 Owners Manual Pg 169 (may differ from 2021)

Selectable Tire Fill Alert (STFA)
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow the customer to select a pressure
to inflate or deflate the vehicle's front and
rear axle tires to and to provide feedback to the
customer while inflating or deflating the
vehicle's tires.
In the Selectable Tire Fill Alert application,
which is located in the apps menu of the
U-connect System, the customer will be able to
select a pressure setting for both the front and
rear axle tire pressures by scrolling through a
pressure range from XX to 15 psi in 1 psi increments
for each axle setting. XX = the vehicle’s
cold placard pressure values for the front and
rear axles as shown on the vehicle placard pressure
label.

The customer may also store the pressure
values chosen for each axle in the radio as a
preset pressure. The customer will be allowed
to store up to two sets of preset values in the
radio for the front and rear axle pressure values.
Once the customer selects the tire pressures for
the front and rear axles that they want to inflate
or deflate to, they can begin inflating or
deflating one tire at a time.
NOTE:
The STFA system will only support inflating or
deflating one tire at a time.
The system will be activated when the TPM
receiver module detects a change in tire pressure.
The ignition must be in the RUN mode,
with the transmission in PARK (P).
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while
inflating or deflating the tire, the TPM sensor
may be in a inoperative position, preventing the
TPM sensor signal from being received. In this
case, the vehicle may need to be moved slightly
forward or backward.

When Tire Fill Alert Mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:
 The horn will chirp once when the selected
pressure is reached to let the user know
when to stop inflating or deflating the tire.
 The horn will chirp three times if the tire is
over inflated or over deflated and will
continue to chirp every five seconds if the
user continues to inflate or deflate the tire.
 The horn will chirp once again when enough
air is added or removed to reach proper
selected pressure level.

I tried the STFA but cant save a new preset setting.. I was able to change the pressures for the front and back but cant save the new threshold>>.

You have to delete an old preset

How to delete the old preset. There is a trash can next to each preset but they are not active button.

Im not sure on yours as mine has a button that says delete or apply do you have a 22?

yes I have a 2022, and have the same buttons but when I hit apply it says I need to delete a profile. and the delete does nothing.

Mines a 19 so im not sure whats up with yours

Can anyone who owns a 2022 Big Horn 2500 tell me if you have the Selectable Tire Fill Alert (STFA) where you can change the tire pressures within the UConnect5 System?

UPDATE: Found it deep within the apps. I was able to change tire pressures to match my configuration.

My STFA presets were easy enough to find, set and "save"....but they won't apply.

2022 BigHorn. I still just see the "Please inflate to 65 psi" warning.

What preset PSI did you set your tires to in the STFA programing? I changed mine from 65 all the way around to 55 front and 60 rear. I haven't received any warnings yet, but I just accomplished this task yesterday and have only driven my truck about 15 miles today.

Did you also reduce the pressure in the tires below 52 PSI?

With the factory setting of 65, the warning light will come on below 52 (20%).

But if the new settings of 55/60 actually took, the light would turn on at 44/48 respectively.

 

[whitexc]

So am I reading this right that I can change this in my 8.4" screen? AlfaOBD is not required to lower the threshold? I tried running 60 psi and got a light. Ideally would like to run 50-55. Hate staring at the light though.
