Dedicated Display
The TPMS display knows where the sensors are
located. It receives the raw temperature and
pressure readings from the TPMS receiver, it reads
several signals from the vehicle and does the
calculation required to generate the various screens.
ON-SCREEN TPMS DEDICATED DISPLAY
When no readings have been received for a tire
location or when the received data correspond to a
parameter range defined as unavailable, then the
reading is considered as not available and appears
as two dash lines "_ _".
The TPMS display is initially configured to define
how many axles and running tires are present on the
vehicle. For current Prevost vehicle models, there
are two axles / tire
configurations are:
CONFIGURATION 1: Axle 1 (Front) Two tires, Axle
2 (Drive) 4 tires, Axle 3 (Tag) 2 tires.
CONFIGURATION 2: Axle 1 (Front) Two tires, Axle
2 (Drive) 2 tires (super Singles), Axle 3 (Tag) 2 tires.
The TPMS display is also configured with several
other parameters, including threshold levels for the
alarms.
The TPMS display turns OFF when the ignition key
is switched OFF.
Operation
The system will monitor all vehicle tires (6 or 8) plus
the spare tire when a spare is supplied.
NOTE
Some vehicle models do not come with a spare
tire.

There are two configurations of vehicle tires to be
supported. One configuration (the most common)
consists of 8 tires total: two tires on the front axle, 4
tires on the drive axle and 2 tires on tag axle. All
screen figures shown in this document relates to this
vehicle configuration. The second tire 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
MONITORING SYSTEM" on page 4
Safety Features and
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.
