The TPMS consists of the following components:
● Receiver module
● Four Tire Pressure Monitoring System sensors
● Various Tire Pressure Monitoring System messages,
which will display in the instrument cluster display
● Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of
the four active road tires. In addition, the instrument
cluster will display a "Tire Low" message and a graphic
showing the pressure values of each tire with the low
tire pressure values highlighted or in a different color.
Tire Pressure Monitoring
System Low Pressure Warning
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those highlighted or in a dif
ferent color in the
instrument cluster display graphic) to the vehicle’s
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update, the pressure values in the
graphic display in the instrument cluster will stop being
highlighted or return to their original color, and the Tire
Pressure Monitoring System Warning Light will turn off.
NOTE:
When filling warm tires, the tire pressure may need to
be increased up to an additional 4 psi (28 kPa) above
the recommended cold placard pressure in order to
turn the Tire Pressure Monit
oring System Warning Light
off.
The vehicle may need to be driven for up t
o 10 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 System Warning 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
instrument cluster will display a "SERVICE 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 System
Warning Light will no longer flash, and the “SERVICE
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:
● Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
