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.). -

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.

7. TIRE INFLATION PROCEDURE FOR VEHICLE WITH TPMS
1) Overview
For the vehicle with TPMS, the tire should be inflated in a method different from the conventional method
since the tire pressure values displayed on the tire pressure gauge and instrument cluster are different
after inflation.
The tire pressure displayed on the instrument cluster should be checked after a certain time delay
(wireless transmission time for wheel module).
The displayed value can be changed after driving even if it was set to the specified value.
2) Tire Inflation Procedure
Park the vehicle on a flat ground and let everyone get off the vehicle. A.
This symptom is occurred as the inflation pressure displayed on the instrument cluster becomes
different by tires as different load is applied to each tire due to driving condition, number of
occupants, irregular temperature change in tire and load condition.
If there is another vehicle equipped with the TPMS, keep the distance from this vehicle for at
least 5 mm to prevent interference of wheel module transmission.
Unload cargoes if they are usually not loaded during driving.
The instrument cluster does not display every pressure change while the air is injected or
discharged to/from the tire. This is because the wheel module sends the pressure value to the
TPMS ECU every minute.
In addition, if there are other vehicles with the TPMS nearby, it might take several minutes to
display the pressure values due to radio jamming and weather condition. -
