SAFETY
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
Telltale 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 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 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 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 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
TPM Telltale Light will turn OFF and the graphic
in the instrument cluster will display a new pres
-
sure 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 condition 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.
The TTPMS consist of the following
components:
Trailer Receiver Module
Trailer Interface Module
Two to twelve tire pressure monitoring
sensors depending on trailer configuration
