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
ЉSERVICE TPM SYSTEMЉ 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:
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 EVIC will also display a
ЉSERVICE TPM SYSTEMЉ
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the
ЉSERVICE TPM SYSTEMЉ
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
ЉSERVICE TPM SYSTEMЉ 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
