3. CAUTIONS
The tire pressure values displayed on the instrument cluster are sent from the wheel modules after
the vehicle is driven for a period of time. Therefore, they are not displayed at initial start (more than
20 minutes have elapsed after ignition off). It can be displayed after 10 minutes of driving at speed of
20 km/h or higher. -
The TPMS uses a radio frequency and a high frequency band between the wheel module and the
TPMS ECU for communication.
Therefore, if the vehicle is equipped with the electronic equipment such as mobile camera monitor
or the vehicle is passing through the area with a strong electromagnetic field, the system may not
operate normally.
For the vehicle equipped with the TPMS, the TPMS warning lamp on the instrument cluster comes
on and pressure values on the EL display is displayed as bars (--) after driving for a certain period of
time if a newly installed tire is not equipped with the wheel module. -

2. LAYOUT 1. OVERVIEW
The TPMS is used to reduce the accident rate, enhance driving stability and avoid an unnecessary fuel
consumption and tire wear by monitoring the tire pressure and temperature to inform the driver of tire
pressure information and its status through the instrument cluster. The wheel module fitted in the tire
transmits the internal data for the tire to the TPMS ECU periodically through the wireless transmission.
The TPMS ECU can detect the positions of the wheel modules fitted to each wheel automatically and
sends the signal on tire condition through the CAN line to the instrument cluster so that the driver can
identify the wheel module in question.

4. TPMS PRESSURE VALUE DISPLAYING PROCESS
The TPMS ECU receives the tire pressure value from the wheel module through the wireless
transmission once every about 30 seconds and displays the pressure value on the instrument cluster
through CAN line.
Under normal circumstances, it transmits the tire pressure value and temperature value together
with its ID (Identification) once every about 30 seconds to reduce the load on the wheel module's
battery. But, in the event of emergency or situation which should give a warning to the driver, it
transmits the data once every about 1 second. Since the battery consumption will be increased
rapidly until the data transmission interval will be returned to normal after certain length of time,
adjust the tire pressure to the specified one after rectifying the cause.
The tire pressure is displayed through the following sequences, which occur at the same
time.
Wheel module detection
(Auto learning)This is a step which receives an ID signal from the wheel module fitted
to the vehicle. When the wheel module sends the signal about twice
every 1 minute, each wheel module will be identified.
Wheel module mounting
location detection
(Auto location)The TPMS ECU check which wheel module is installed to which tire.

5. LOW TIRE PRESSURE WARNING
If the tire pressure is less than 13% of the proper value calculated by the TPMS ECU depending on the
ambient temperature for more than 8 minutes, the 1st low tire pressure warning is given. And, if the tire
pressure is less than 20% for more than 4 minutes, the 2nd warning is given. At this time, the "Check
tire" message is displayed on the DOT LCD display and the global warning lamp comes on.
ECU receives the ambient temperature signal from the instrument cluster through CAN
communication and calculates the proper tire pressure to correct it since the tire pressure changes
depending on the ambient temperature.

6. DISPLAY AND WARNING LAMPS RELATED TO TPMS
This lamp comes on when the engine is initially started or the ignition
switch is pressed ON (for about 4.0 seconds). Then, it goes off if the
system is normal.
It comes on if an error occurs in any component related to the TPMS
regardless of tire inflation pressure. -
-
This lamp comes on when the engine is initially started or the ignition
switch is pressed ON (for about 4.0 seconds). Then, it goes off if the
system is normal.
In the event of TPMS system (including sensor) failure, it flashes for 70
seconds at interval of 0.4 seconds and comes on.
Comes on when the tire pressure is low. -
-
-
It informs the driver of current tire pressure and abnormalities such as
loss or over inflation by displaying them on the display.
The driver can see the current tire pressure by pressing the TRIP
switch (press for 80 ms~1 sec.). -

Low tire pressure warning
If the tire pressure is less than 13% of the proper value for more than 8 minutes, the 1st low tire
pressure warning is given. And, if the tire pressure is less than 20% for more than 4 minutes, the
2nd warning is given. The message "Check tire" is displayed on the instrument cluster DOT LCD

Priority of TPMS warnings
The situation can occur in which two warning messages are displayed depending on the vehicle
condition. If this happen, the warning messages are displayed according to the priority below.
