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 longer flash, and the ⬙CHECK TPM SYS-
TEM⬙ text message will no longer display.
NOTE:
If your vehicle is equipped with a compact
spare wheel and tire assembly it does not have a tire
pressure monitoring sensor. Therefore, it will not be
monitored by the Tire Pressure Monitor System (TPMS).
In the event that the compact spare tire is swapped with
a low pressure road tire, the next ignition key cycle will
still show the “Tire Pressure Monitoring Lamp” to be
ON, a chime to sound, and the Electronic Vehicle Infor-
mation Center (EVIC) will still show the low tire pressure
value flashing on the graphic display. However, driving
the vehicle for up to 10 minutes above 15 mph (25 km/h)
will display a “CHECK TPM SYSTEM” text message on
the EVIC. This text message will then be followed by a
graphic, with “- -“ in place of the flashing low pressure
value. For every subsequent key cycle, the “Tire Pressure
Monitoring Lamp” will be ON, a chime will sound, a
“CHECK TPM SYSTEM” text message will be display in
the EVIC, and the graphic display will have “- -“ in place
of the pressure value of the spare tire location. Once the
original road tire has been properly repaired, and put
back onto the vehicle in place of the compact spare tire.
The TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of “- -“, and the
“Tire Pressure Monitoring Lamp” will be OFF as long as
none of the road tire(s) are below the low pressure
warning threshold. The vehicle may need to be driven for
up to 10 minutes above 15 mph (25 km/h) for this update
to happen.
