update, the pressure values in the graphic display in the
EVIC/DID will return to their original color, and the
"Tire Pressure Monitoring Telltale Light" will turn off.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
Service TPMS Warning
When a system fault is detected, the "Tire Pressure
Monitoring 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/DID will
display a SERVICE 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 is cycled, this sequence will repeat, pro-
viding 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 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.
