466 STARTING AND OPERATING
Service TPMS Warning
When a system fault is detected, the "Tire Pressure Moni-
toring 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 EVIC 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 "Tire Pressure Monitoring Telltale
Light" will no longer flash, and the SERVICE TPM
SYSTEM 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. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
