The EVIC will also display a
ЉSERVICE TPM SYSTEMЉ
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, the
ЉSERVICE TPM SYSTEMЉ
message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
the
ЉSERVICE TPM SYSTEMЉ message exists.
NOTE: There is no tire pressure monitoring sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. 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 Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a pressure value in
the different color graphic display and an
ЉInflate to
XXX kPa
Љ message will be displayed. After driving the
vehicle for up to 20 minutes above 15 mph (24 km/h), the
Tire Pressure Monitoring Telltale Light will flash on and
off for 75 seconds and then remain on solid. In addition,
the EVIC will display a “SERVICE TPM SYSTEM
Љ mes-
sage 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 Telltale Light will flash on and off for 75
seconds and then remain on solid, and the EVIC will
display a
ЉSERVICE TPM SYSTEMЉ 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 automatically.
In addition, the Tire Pressure Monitoring Telltale Light
will turn OFF and the graphic in the EVIC 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
