providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale

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.
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
