Tpms Pressure Value Displaying Process - SSANGYONG Korando 2013 Manual

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)
Wheel module mounting
location detection
(Auto location)
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.
The TPMS ECU check which wheel module is installed to which tire.
