2020 Ram 1500 TPMS

SAFETY 231
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring System Warning
Light” will no longer flash, and the "SERVICE TPM
SYSTEM" message will no longer display, and a pressure
value will display in place of the dashes. A system fault can
occur due to any of the following:
• Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as the
Tire Pressure Monitor (TPM) sensors
• Installing aftermarket window tinting that contains mate -
rials that may block radio wave signals
• Accumulation of snow or ice around the wheels or wheel housings
• Using tire chains on the vehicle
• Using wheels/tires not equipped with TPM sensors

A system fault may occur due to an incorrect TPM sensor loca -
tion condition. When a system fault occurs due to an incorrect
TPM sensor location, the “Tire Pressure Monitoring System
(TPMS) Warning Light” will flash on and off for 75 seconds
and then remain on solid. The system fault will also sound a
chime. In addition, the instrument cluster will display a “Tire
Pressure Temporarily Unavailable” message in place of the
tire pressure display screen. If the ignition switch is cycled, this sequence will repeat, providing the system fault still
exists. If the system fault no longer exists, the “Tire Pressure
Monitoring System Warning Light” will no longer flash and
the tire pressure display screen will be displayed showing the
tire pressure values the correct locations.

Vehicles With Non Matching Full Size Spare Or Compact
Spare
• The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will not
monitor the pressure in the non matching full size spare or
compact spare tire.
• If you install the non matching full size spare or compact spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
switch cycle, the Tire Pressure Monitoring System (TPMS)
Warning Light and a “LOW TIRE” message will remain
ON and a chime will sound. In addition, the graphic in the
instrument cluster will still display a pressure value in a
different color and an “Inflate to XX” message.
• After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the Tire Pressure Monitoring System
(TPMS) Warning Light will flash on and off for 75 seconds
and then remain on solid. In addition, the instrument

cluster will display a "SERVICE TPM SYSTEM" message
for a minimum of five seconds and then display dashes (--)
in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will sound, the Tire Pressure Monitoring System (TPMS)
Warning Light will flash on and off for 75 seconds and
then remain on solid, and the instrument cluster will
display a "SERVICE TPM SYSTEM" message for a
minimum of five seconds and then display dashes (--) in
place of the pressure value.
• Once you repair or replace the original road tire and rein -
stall it on the vehicle in place of the non matching full size
spare or compact spare, the TPMS will update automati -
cally. In addition, the Tire Pressure Monitoring System
(TPMS) Warning Light will turn OFF and the graphic in
the instrument cluster will display a new pressure value
instead of dashes (--), as long as no tire pressure is below
the low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the TPMS
to receive this information. Tire Fill Alert
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.
NOTE:
• 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 a positive increase in tire
pressure is detected by the TPM system while inflating the
tire. The ignition must be in the RUN mode, with the trans -
mission in PARK (P).
NOTE:
It is not required to have the engine running to enter Tire Fill
Alert mode.
