Check 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 will display a
⬙
CHECK
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 key 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 lon-
ger flash, and the
⬙
CHECK 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 driv-
ing 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. 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 TPM
sensors.
The EVIC will also display a
⬙
CHECK TPM
SYSTEM
⬙
message for a minimum of five sec-
onds when a system fault related to an incor-
rect sensor location fault is detected. In this
case, the
⬙
CHECK TPM SYSTEM
⬙
message is
then followed with a graphic display with pres-
sure values still shown. This indicates that the
pressure 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
⬙
CHECK
TPM SYSTEM
⬙
message is displayed.
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire
assembly has a tire pressure monitoring sensor
that can be monitored by the TPMS.
2. If you install the full size spare in place of a
road tire that has a pressure below the low-
pressure warning limit, upon the next ignition
key cycle, a chime will sound and the “Tire
Pressure Monitoring Telltale Light” will turn ON.
In addition, the EVIC will display a Low Tire
Pressure message and a graphic showing the
low tire pressure value flashing.
3. After driving the vehicle for up to 20 minutes
above 15 mph (25 km/h) the “Tire Pressure
Monitoring Telltale Light” will turn OFF, as long
as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
4. The EVIC will display a graphic showing the
tire pressure value in place of the flashing low
tire pressure value.
