configuration consist of 6 tires total: 2 tires on the
front axle, 2 tires on the drive axle (super single
tires) and 2 tires on the tag axle. The vehicle tire
configuration is selected with a parameter (Refer
to "TIRE PRESSURE MONITORING SYSTEM"
on page 4 in Section 7 Safety Features and
Equipment for more information). When the
display is configured for 6 tires, the drive axle tires
appears as one large tire on both side instead of
twin tires as illustrated in this document and there
is one reading appearing on each side instead of
two as illustrated in this document.
Start-up
When the ignition switch is turned to ON, the
following screen appears on the TPMS Display.
Dash lines are displayed meaning that no pressure
data have been received by the display.
As illustrated, the pressure readings will appear
replacing the dash lines as the TPMS display
starts to receive pressure data from the TPMS
receiver. It can take 1 minute to get all pressure
readings updated since the sensors transmit at a
one-minute interval.The user can flip through the
menus.
Pre-Trip Check
When one of the preconditions defined to start the
pre-trip check is met, the TPM display enters into
a pre- trip check routine and the screen shown
below appears. The preconditions to initiate the
pre-trip are: Park brake removed Or No activity on
the display menu keys for a defined time (Key
pressed timeout). After a pre-trip, the display is in
a "drive" mode with bottom menu replaced by the
alarm status. The display remains in this mode
until one of the following occurs: A menu key is
touched while the park brake is applied, or the park
brake does a transition from released to park brake
applied.
During the pre-trip check, the pressure readings for
the different wheels become all available.
The pre-trip check ends, either when: the pressure
readings have been received for all running wheels
or the pre-trip check maximum time has elapsed. It
was selected to provide sufficient time for all
wheel sensors to wake-up and send a first reading.
The pre-trip check is aborted and the bottom menu
reappears if the park brake was active and the
user press one of the menu keys.
Upon completion of the pre-trip check, the TPMS
display will come up with one of the following
screens:
A rectangle around each pressure and temperature
reading of the tires that have an issue is blinking to
draw the attention to the defective tires.
In the case of multiple errors at the same time, the
highest priority error is displayed at the bottom.
"Flat Tire" has the highest priority followed by
