RAM 2015 1500, Operating Information Manual, Page: 355 / 998

•
After driving the vehicle for up to 20 minutes
above 15 mph (25 km/h) the “Tire Pressure
Monitoring Telltale Light” will turn OFF and
the pressure value will be updated and return
to it’s original color, as long as no tire pres-
sure is below the low-pressure warning limit
in any of the four active road tires.
Vehicles With Non Matching Full Size Spare
•
The compact spare tire does not have a TPM
sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.
•
If you install the 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 EVIC/DID will still display a
flashing pressure value or a pressure value
in a different color.
•
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 addition, the EVIC/
DID 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 EVIC/DID will dis-
play 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 compact spare, the TPMS will update
automatically. In addition, the TPM Telltale
Light will turn OFF and the graphic in the
EVIC/DID 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 Pressure Information System
(TPIS) 3500 Series Trucks
Your vehicle may be equipped with a Tire Pres-
sure Information System (TPIS).
The Tire Pressure Information System (TPIS)
uses wireless technology with wheel rim
mounted electronic sensors to transmit tire
pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.
The TPIS consists of the following components:
•
Receiver module
•
Four TPM sensors (Single Rear Wheel
(SRW) applications)
•
Six TPM sensors (Dual Rear Wheel (DRW)
applications)
