TPMS TRANSMITTER (TIRE PRESSURE SENSOR)
The TPMS transmitter combines the valve and tire
pressure sensor in a single unit. The TPMS transmit
-
ters are mounted inside the tires. The TPMS trans-
mitter measures tire pressure directly with its tire
pressure sensor and sends radio frequency signals
to the ETACS-ECU <vehicles without Keyless Oper
-
ation System> or KOS&OSS-ECU <vehicles with
Keyless Operation System>. The TPMS transmitter
includes acceleration sensor that senses tire rota
-
tion, and change tire pressure sampling and data
transmission timing when vehicle is running.
NOTE: Use only genuine wheels. The use of
non-genuine wheels may cause the improper instal
-
lation of the TPMS transmitters, possibly resulting in
air leakage and damage to the TPMS transmitter.
TIRE PRESSURE SAMPLING TIMING
NOTE: Vehicle moving = vehicle speed: approxi-
mately 25 km/h or more
DATA TRANSMISSION TIMING
If a sampled pressure varies by 10 kPa from the last
transmitted pressure value, an additional transmis
-
sion will occur.
NOTE:
*
: Once every 15 seconds for first 30 trans-
mission after vehicle starts moving.
