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 axle / tire configurations. These
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 power supply 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 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.

PRE-TRIP CHECK IN PROGRESS

PSI

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.
