light will turn off. The vehicle may need to be driven for up
to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check 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. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. The
Tire Pressure Monitoring Telltale light will turn off when
the fault condition no longer exists. 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.
NOTE:
Vehicles with Full-Size Spare
1. The matching full-size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be moni-
tored 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,
a chime will sound and the TPMS Telltale light will turn
on upon the next ignition key cycle.
3. Driving the vehicle for up to 20 minutes above 15 mph
(25 km/h) will turn off the TPMS Telltale light, as long as
no tire pressure is below the low-pressure warning limit
in any of the four active road tires.
