TIRE PRESSURE THRESHOLD VALUES

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 WCM via receiver antenna assembly. The TPMS
transmitter includes acceleration sensor that senses
tire rotation, 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 (15 mph) or more

.

DATA TRANSMISSION TIMING

If a sampled pressure varies by

±10 kPa

(1.5psi) from the last transmitted pressure
value, an additional transmission will occur.

NOTE:

*

: Once every 15 seconds for first 30 trans-

mission after vehicle starts moving.

WARNINGS/ALARMS

M2422000900037

If the TPMS fails or the tire pressure is low, the WCM
warns the driver of that state by the TPMS warning
light and the multi information display in the combina-
tion meter.
