3. The Display
The display unit is the interface between the TPMS and the user. The
display has a graphical
representation of the vehicle with
tire icons on the left side of the
screen, a thermometer icon and
temperature reading on the upper
right, and a tire status icon and
pressure reading on the lower right
side.
There is a status lamp on the right side of the display. Below the status
lamp there is a control button.
Pressing the control button will display
individual tire pressure and temperature readings; a darken tire icon on
the vehicle graphic indicates the associated tire location.
On the right edge of the display unit there is a button for programming
the system. Detail description of the set up procedures will be
described in a later section.
3. 1 Operation
When the vehicle power is on the status lamp will light up. The display
will show the current tire pressure and temperature
one-by-one from
tire No. 1 to the last tire. The display then turns off and only the status
light remains lit.
Normally the light is in green color. When the TPMS
detects a low tire pressure situation or when any tire is rapidly losing
air, the lamp turns to red and an audible warning signal will be issued.
For other tire pressure and/or temperature abnormality, the status light
would be in yellow.
The order of tire information display for different vehicles is as follows:

3. 2 Warnings
Upon detection of abnormal tire pressure and/or temperature the
system will display one of the following warnings. The display lasts 8
seconds and then will switch to a screen as shown in
Abnormal
Situation Display
(described in the next section). For severe warnings
(low pressure and rapid pressure change) the system will also sound
an 8-second alarm.
Low pressure or blowout
The tire icon is hollow;
indicating tire pressure is
low or tire is rapidly
losing 3+ PSI of air within
a number of seconds.
Slow air leak
The tire icon is 2/3 full;
indicating tire pressure
depletion of 3 PSI or
more within 2 to 10
minutes.
High tire pressure
The tire icon is full with
an outer shell; indicating
the tire pressure is too
high.
High temperature
The high-temp icon is
visible; indicating tire
temperature is too high.
3.3 Abnormal Situation Display
A persistent abnormal tire situation (with possibly several tire
abnormalities) will cause one of the following warnings to be displayed.
The warnings are listed below in the order of precedence for display
selection (from multiple abnormalities) by the system.
