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
sound. In addition, the graphic in
the instrument cluster will still
display a flashing pressure value
corresponding to the compact tire
position.
• After driving the vehicle for up to 20
minutes above 15 mph (24 km/h),
the TPMS light
seconds and then remain lit. The
instrument cluster will then display a
"Service Tire Pressure System"
message for a minimum of five
seconds and then displays dashes (--)
in place of the pressure value.
• Each subsequent ignition switch
cycle, will be followed by a beeping
sound, the TPMS light
for 75 seconds and then remain lit.
The instrument cluster will then
display a "Service Tire Pressure
will
System" message for a minimum of
five seconds and subsequently
