WHEEL AND TIRES
02–12–6
Sensing Function
• The sensing function periodically monitors the following data and sends it to the TPMS control module.
— Tire pressure
— Tire temperature
— Tire acceleration
— Voltage of the built-in battery
• Intervals of tire data monitoring and data transmission to the TPMS control module differ depending on the
operational mode (varies according to vehicle conditions).
Self-diagnostic Function
• The self-diagnostic function continuously performs malfunction diagnosis for each sensing function item. If any
abnormality is found by the malfunction diagnosis, the data is sent to the TPMS control module.

• The TPMS warning light and the TPMS warning
buzzer are built into the instrument cluster.
• In the event of any abnormality in tire pressure or
in the system, signals from the TPMS control
module illuminate the warning light and sound the
warning buzzer to alert the driver.
• Signals from the TPMS control module are sent
through the CAN communication lines.

Construction
• The TPMS control module is installed in the upper part of the instrument cluster.
Operation
• Through the built-in antenna, the TPMS control module receives data on each tire transmitted from the wheel
units.
• The module monitors the tire pressure of each tire and the wheel units for abnormalities using the received
data. If any abnormality is found, it controls the TPMS warning light and buzzer to alert and notify the driver.
• The TPMS control module controls the following functions based on the received data:
