If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, the ⬙SERVICE TPM SYSTEM⬙
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. 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.
NOTE: Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not moni-
tor the tire 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 key cycle, a chime will sound and
the Tire Pressure Monitoring Telltale Light will still turn
ON due to the low tire. The “Inflate Tire to XX” message
and the graphic with the low tire pressure flashing or in
a different color will be displayed.
3.
However, 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” message for a minimum of
five seconds and then display dashes (- -) in place of the
pressure values.
