2019 Ram 4500 Chassis Cab TPMS

182 SAFETY
Vehicles With Non Matching Full Size Spare Or Compact
Spare
• The non matching full size spare or compact spare tiredoes 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 TPM Telltale 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 TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. In addi -
tion, 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 TPM Telltale 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 TPM Telltale 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.
Trailer Tire Pressure Monitoring System (TTPMS)
The Trailer Tire Pressure Monitoring System (TTPMS) is a
feature that will display the trailer tire pressure values and
warn the driver of a low trailer tire pressure, based on the
drivers set target tire pressure value, through the Instrument
Cluster (IC).
The TTPMS monitors the pressure of each tire and warns the
driver, through the IC, when either a low tire pressure condi -
tion or a TPM sensor or system malfunction condition exists.
The IC will display the actual tire pressure or dashes for each
of the trailer tires in the correct trailer position, based on
trailer configuration.

SAFETY 183
The TTPMS consist of the following components:
• Trailer Receiver Module
• Trailer Interface Module
• Two to twelve tire pressure monitoring sensors dependingon trailer configuration

The TTPMS is configured though the trailer settings menu in the
Uconnect system by selecting the desired trailer number (up to
four trailers can be configured), the number of axles (1 - 3), the
number of trailer tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. Refer to “Uconnect Settings” in “Multimedia” for
further information.

Tire Pressure Monitoring Low Pressure Warnings
When a tire pressure low in one or more of the active road
tires is detected a chime will sound. In addition, the instru-
ment cluster will display a graphic showing the pressure
values of each tire with the low tire pressure values in a
different color. An “Inflate to XXX” message will also be
displayed.
NOTE:
"XXX" = TPM trailer tire target pressure value programmed
by the customer Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a
different color in the instrument cluster graphic) to the
customer programmed target tire pressure value as shown in
the “Inflate to XXX” message. Once the system receives the
updated tire pressures, the system will automatically update
the graphic display in the instrument cluster will return to
it’s original color. The vehicle may need to be driven for up
to 10 minutes above 15 mph (24 km/h) in order for the
TTPMS to receive the updated information.
Service TTPMS Warning
If a system fault is detected, the system fault will sound a
chime and the instrument cluster will display a “Trailer Tire
Pressure System Service Required” message for a minimum
of five seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being received.
Once the system fault is corrected the "Trailer Tire Pressure
System Service Required" message will no longer be
displayed and the dashes will be replaced by pressure
values. The vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order for the TTPMS
to receive the updated information.
