Flashers

[2014 Ram]

Quick question...this has never happened to me. 2022 Ram Bighorn 5.7 Hemi with 27,000 miles... Sitting in my truck at lunch time with the air conditioner on for about 20 minutes like I do everyday. Just now it sounded the horn once and turned the emergency flashers on. No lights or anything came on the dashboard or radio. I shut the engine off and cranked it back up and now it's back to normal. What the heck causes this? Thank you

Oh yeah and it flipped to the tire pressure page on my dashboard. But everything looks fine at between 37 and 39 PSI all four tires

The one beep is tire pressure monitor system. The higher trim newer trucks have the tire pages and system status, but on my lightly optioned Bighorn, the system works but have no pages in display, not for my lowly Bighorn.

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold
placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the instrument
cluster will display a graphic showing the pressure
values of each tire with the low tire pressure
values in a different color, or the Uconnect
radio will display a TPMS message; when this
occurs you must increase the tire pressure to
the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease.

This feature notifies the user when the placard tire pressure
is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature through use of the customer settings in the
radio.
• Only one tire can be filled at a time when using the Tire
Fill Alert system.
• The Tire Fill Alert feature cannot be entered if an existing
TPM system fault is set to “active” or if the system is in
deactivation mode (if equipped).
The system will be activated when there is over 1.5 psi (10
kPa) of change in tire pressure. The ignition must be in the
RUN mode, with the transmission in PARK (P).
NOTE: It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
• The horn will chirp to let the user know when to stop
filling the tire, when it reaches recommended pressure.
• The horn will chirp three times if the tire is over filled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
• The horn will chirp once again when enough air is let
out to reach proper inflation level.
• The horn will also chirp three times if the tire is then
under-inflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
