Dodge RAM 1500 2019, User Manual

Page: 83 / 268

• Installing aftermarket window tinting that
contains materials 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 location condition. When a sys-
tem fault occurs due to an incorrect TPM
sensor location, the “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 Tempo-
rarily 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 “TPMS
Warning Light” will no longer flash and the
tire pressure display screen will be displayed
showing the tire pressure values for the cor-
rect locations.
Vehicles With Non Matching Full Size Spare Or
Compact Spare
• The non matching full size spare or com-
pact 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 TPMS Warning
Light and a “LOW TIRE” message will re-
main ON and a chime will sound. In addi-
tion, the graphic in the instrument cluster
will still display a pressure value in a differ-
ent color and an “Inflate to XX” message.
• After driving the vehicle for up to 20 min-
utes above 15 mph (24 km/h), the 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 TPMS Warning
Light will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment 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 reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically.
In addition, the 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.
