RAM 2015 1500, Operating Information Manual, Page: 354 / 998

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 EVIC/
DID graphic) to the vehicle’s recommended cold
placard pressure inflation value as shown in the
" Inflate to XX " message. Once the system re-
ceives the updated tire pressures, the system
will automatically update, the graphic display in
the EVIC/DID will return to it’s original color, and
the “Tire Pressure Monitoring Telltale Light” will
turn off. 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.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring Telltale 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 EVIC/DID will display a
" SERVICE TPM
SYSTEM " message for a minimum of five sec-
onds and then display dashes (- -) in place of
the pressure value to indicate which sensor is
not being received.
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 Telltale Light” will no longer
flash, and the
"
SERVICE TPM SYSTEM
"
mes-
sage 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 follow-
ing:
•
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors.
•
Installing aftermarket window tinting that con-
tains 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.
Vehicles With Matching Full Size Spare
•
The matching full size spare wheel and tire
assembly has a TPM sensor that can be
monitored by the TPMS.
•
If you install the full size spare in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
ignition switch cycle, a chime will sound and
the “Tire Pressure Monitoring Telltale Light”
will turn ON. In addition, the EVIC/DID will
display a “LOW TIRE” message and a
graphic showing the low tire pressure value
in a different color. An
" Inflate to XX " mes-
sage will also be displayed.
