SAFETY267
Service TPMS Warning
The Tire Pressure Monitoring System Warning Light
will flash on and off for 75 seconds, and remain on
solid when a system fault is detected. The system
fault will also sound a chime. The instrument
cluster display will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds.
This message is then followed by a graphic display,
with “--“ in place of the pressure value(s),
indicating which Tire Pressure Monitoring System
sensor(s) 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 System Warning Light will no longer
flash, the "SERVICE TPM SYSTEM" message will
not be present, and a pressure value will be
displayed instead of dashes. A system fault can
occur by any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Lots of snow or ice around the wheels or wheel
housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
NOTE:A TPMS sensor is not offered on any size spare tire.
In either option of having a full size spare equipped
or not, the tire pressure is not monitored or
displayed on the cluster for the corresponding
spare tire location. If you install the 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 Tire Pressure Monitoring System
Warning Light will remain on, a chime will sound,
and the instrument cluster display will still display
a pressure value in the different color graphic
display and an “Inflate to XX” message will be
displayed. After driving the vehicle for up to
20 minutes above 15 mph (24 km/h), the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on
solid. In addition, the instrument cluster display
will display a “SERVICE TPM SYSTEM" message for
five seconds and then display dashes (--) in place
of the pressure value. For each subsequent
ignition switch cycle, a chime will sound, the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on
solid, and the instrument cluster display will
display a "SERVICE TPM SYSTEM" message for 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 spare tire, the TPMS will update auto -
matically. In addition, the Tire Pressure Monitoring System
Warning Light will turn off and the graphic in the
instrument cluster display 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.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can
be deactivated by replacing all four wheel and tire
assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such
as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
sensors. Then, drive the vehicle for 20 minutes
above 15 mph (24 km/h). The TPMS will chime,
the TPMS Warning Light will flash on and off for 75
seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place of
the pressure values.
