mended cold placard pressure inflation value as
shown in the "Inflate Tire to XX" message. Once
the system receives the updated tire pressures,
the system will automatically update, the
graphic display in the DID will return the pres-
sure values shown to their original color, and
the "TPM Telltale 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 receive this information.
Service TPMS Warning
If a system fault is detected, the "TPM Telltale
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 DID 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 switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the "TPM
Telltale Light" will no longer flash, and the
"SERVICE TPM SYSTEM" message will no
longer display, and a pressure value will display
244
in place of the dashes. A system fault can occur
due to any of the following:
1. Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors.
2. Installing aftermarket window tinting that
contains materials that may block radio
wave signals.
3. Accumulation of snow or ice around the
wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
The DID will also display a "SERVICE TPM
SYSTEM" message for a minimum of five sec-
onds when a system fault related to an incorrect
sensor location fault is detected. In this case,
the "SERVICE TPM SYSTEM" message is then
followed with a graphic display with pressure
values still shown. This indicates that the pres-
sure values are still being received from the
TPM sensors but they may not be located in the
correct vehicle position. The system still needs
to be serviced as long as the "SERVICE TPM
SYSTEM" message is displayed.
Vehicles With Compact Spare
1. The compact spare tire does not have a TPM
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 switch cycle, the "TPM Telltale Light"
will remain ON and a chime will sound. In
addition, the graphic in the DID will still
display the low pressure values in a different
color and the "Inflate Tire to XX" message.
3. 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 DID will
display a "SERVICE TPM SYSTEM" mes-
sage for a minimum of five seconds and then
display dashes (- -) in place of the pressure
value.
