SYSTEM STRUCTURE 

Once the vehicle speed exceeds 28 mph (45 km/h), the TPMS control unit monitors all four tires and the 
system. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator. If it 
detects a problem in the system, it turns on the TPMS indicator. 

Control unit 

Mounted inside of the dash, the TPMS control unit receives pressure sensor ID signals every time the vehicle 
speeds exceeds 28 mph (45 km/h). It also receives signals from the transmitters for tire pressure and the sensor 
condition, and it continuously monitors and controls the system. 

Indicators 

Two indicators are in the gauge control module: The low tire pressure indicator comes on when any tire 
pressure is low, and the TPMS indicator that comes on only if there's a problem with the system. 

The low tire pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) 
location.

Tire pressure sensor 

Each sensor is an integrated unit made up of the tire valve stem, a pressure sensor, and a transmitter. The unit is 
attached to the inside of the wheel, around the valve stem. The sensor transmits the internal tire information to 
the control unit once every 60 seconds when the vehicle speed exceeds 28 mph (45 km/h). When the TPMS 
control unit receives a tire pressure signal that is less than: Except SC model 190 kPa (1.9 kgf/cm

2

 ,28 psi), SC 

model 175 kPa (1.8 kgf/cm

2

 , 25 psi), the control unit then turns on the low tire pressure indicator. When that 

tire's pressure is increased to more than: Except SC model 210 kPa (2.1 kgf/cm

2

 ,30 psi), SC model 200 kPa 

(2.0 kgf/cm

2

 ,29 psi), and the vehicle is driven above 28 mph (45 km/h) the transmitter sends the tire pressure 

signal to the control unit, and then the control unit turns the indicator off. 

Do not mix the tire pressure sensor with another TPMS type. 

Sensor active: 



When the wheel rotates over 28 mph (45 km/h), the sensor detects the momentum, switches the sensor to 
the normal function mode.  



The LF (low frequency) signal of the TPMS initializer tool makes the sensor active even though the 
vehicle is stopped. The tire pressure sensor goes into sleep mode when the acceleration sensor detects the 
wheel is stationary for 5 minutes or more continuously.

Wheels 

TPMS will not work unless TPMS type wheels are installed on the vehicle. There are three different type 
wheels used. The original equipment wheels have a "TPMS" mark (A) on them and counterweights (B) cast into 
the opposite side of the spoke to counter balance the weight of the tire pressure sensor (C).

SYSTEM COMMUNICATION 



When the vehicle is traveling more than 28 mph (45 km/h), an RF (radio frequency) band wave signal is 
continuously transmitted from each tire pressure sensor to the control unit.  



When the wheels rotate; and the tire pressure sensors momentum is detected, switching them from sleep 
mode to normal function mode. After the vehicle is stationary for 5 minutes, the sensors switch from 
normal function mode back to sleep mode to extend their battery life.  



Each tire pressure sensor has its own ID to prevent jamming by similar systems on other vehicles. After 
memorizing all the sensor IDs, the control unit receives only those specific signals.  



An ID cannot be memorized automatically. The control unit knows which ID belongs to each tire 
pressure sensor. This recurring ID confirmation prevents any confusion in the system as a result of 
normal tire rotation.
