The system will automatically update, the graphic display
of the pressure value(s) will return to its original color and
the Tire Pressure Monitoring Telltale Light will extinguish
once the updated tire pressure(s) have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Service TPM System Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The instrument cluster display will display a “SERVICE
TPM SYSTEM” message for a minimum of five seconds.
This message is then followed by a graphic display, with “-
-“ in place of the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) 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, the SERVICE TPM SYSTEM message will not be
present, and a pressure value will be displayed instead of
dashes. A system fault can occur by any of the following:
Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
Installing some form of aftermarket window tinting that
affects radio wave signals.
Lots of snow or ice around the wheels or wheel hous-
ings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM sensors.
