Tire Pressure Monitoring System (Tpms) Outline; Tire Pressure Monitoring - Mazda RX-8 2004 Service Highlights

TIRE PRESSURE MONITORING SYSTEM (TPMS) OUTLINE

• The tire pressure monitoring system (TPMS) has been adopted to assist the driver in understanding the tire
status. It alerts the driver with the TPMS warning light and buzzer if there is an excessive drop in air pressure or
air pressure higher than a specified value is detected.
Caution
• Each wheel unit has its own preset identification code. If a system component is replaced, the
system becomes inoperative since the TPMS control module cannot recognize the identification
codes. Therefore, be sure to configure the identification codes of wheel units when any of the
following items have been performed. For the identification code configuration procedure, refer to
the Workshop Manual.
— Disc wheel replacement
— Wheel unit replacement
— TPMS control module replacement
Note
• Perform tire pressure adjustment before driving. (When tires are cold.)
• Tire pressure changes due to changes in ambient temperature and internal tire temperature.
— In an area or a season with varying of temperatures, tire pressure will change due to ambient
temperature change. If the tire pressure is lower than the lower-limit pressure due to low ambient
temperature, the TPMS warning light may illuminate. Adjust the pressure when the TPMS warning
light illuminates.
— Tire pressure rises after driving because the internal temperature of the tire is high, If tire pressure is
adjusted to the standard value when the internal temperature of the tire is high, the tire pressure
lowers when the internal temperature decreases to the same level as the ambient temperature. If the
tire pressure is lower than the lower-limit temperature, the TPMS warning light may illuminate.
• As a general reference, air pressure changes approx.10 kPa {0.1 kgf/cm
temperature changes 10 degrees.
