272 SAFETY
The TPMS consists of the following
components:
Receiver module
Four Tire Pressure Monitoring System
sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning
Light
Service TPMS Warning
When a system fault is detected, the Tire
Pressure Monitoring System (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 "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition 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
“SERVICE TPM SYSTEM” message 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 following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
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
Vehicles With Compact Spare — If Equipped
1. The compact spare tire does not have a
Tire Pressure Monitoring System sensor.
Therefore, the TPMS will not monitor the
pressure in the compact spare tire.
2. 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 cycle, the TPMS Warning Light will
remain on and a chime will sound. In
addition, the graphic in the instrument
cluster will still display a different color
pressure value.
3. After driving the vehicle for up to
20 minutes 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 five
seconds and then display dashes (--) in
place of the pressure value.
