will automatically update, the graphic
display in the instrument cluster will
stop flashing, and the TPMS 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 acquire and process the
updated information.
"Service Tire Pressure System"
Warning
If a system fault is detected, the TPMS
light will flash for 75 seconds and
then remain lit followed by a beeping
sound. Therewith, the instrument
cluster will display a "Service Tire
Pressure System" message for a
minimum of five seconds and then
display dashes (- -) in place of the
pressure value to indicate which
sensor is ineffective.
If the ignition switch is cycled, the
sequence will repeat, in case the
system fault still persists. If the system
fault no longer exists, the TPMS light
will no longer flash, and the
"Service Tire Pressure 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:
• Signal interference due to electronic
devices or driving next to facilities
emitting the same radio frequencies
as the TPMS sensors.
• Installing aftermarket window
tinting that contains 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 TPMS sensors.
The instrument cluster will also display
a "Service Tire Pressure System"
message for a minimum of five
seconds when a system fault related to
an incorrect sensor location fault is
detected. In this case, the "Service Tire
Pressure System" message is then
followed with a graphic display with
pressure values still shown. This
indicates that the pressure values are
still being received from the TPMS
sensors but they may not be located in
the correct vehicle position. The
system still needs to be serviced as
long as the "Service Tire Pressure
System" message is displayed.
Vehicles with Compact Spare Tire
• The compact spare tire does not
have a TPMS sensor. Therefore, the
TPMS will not monitor the pressure
of the compact spare tire.
• If you replace a pneumatic having
pressure below the low-pressure
warning limit, with the compact
spare tire, on the next ignition
switch cycle, the TPMS light
illuminate followed by a beeping
