TW–6TIRE AND WHEEL – TIRE PRESSURE WARNING SYSTEM
TW
SYSTEM DESCRIPTION
1. DESCRIPTION OF SYSTEM
(a) A tire pressure warning antenna and receiver is
equipped with a tire pressure sensor and a
transmitter and is installed in each tire wheel. The
sensor measures the tire pressure and internal
temperature of the tire. Then the measured value
and transmitter ID are transmitted to the tire
pressure monitor receiver on the body as radio
waves, which are sent to the tire pressure warning
ECU. If the transmitter ID has already been
registered, the ECU compares the measured air
pressure value with the standard value. When the
value is less than the standard value registered in
the tire pressure warning ECU, the warning light in
the combination meter turns on.
2. WHEN TIRE PRESSURE WARNING LIGHT IS LIT
(a) When the tire pressure warning light does not turn
off, or when it turns on during driving, check the tire
pressure. If the tire pressure warning light turns on
within several hours after adjusting the tire
pressure, the tire may have a slow air leak.

(b) Under the following conditions, the system may not
function properly;
• Areas, facilities or devices that use similar radio
frequencies are located in the vicinity of the
vehicle.
• Devices using similar radio frequencies are used
in the vehicle.
• Large amounts of snow or ice are stuck to the
vehicle, especially on the wheels and around the
wheel houses.
• The battery of the transmitter is depleted.
• Tires and wheels without tire pressure warning
valves and transmitters are used.
• Snow tires and tire chains are used.
• If wheels other than the specified ones are used,
the system may not function properly because
different radio waves are transmitted from the tire
pressure warning valve and transmitter.
• Depending on the tire type, the tire pressure
warning valve and transmitter may not function
properly even though the specified wheels are
used.
• The system may not function properly if it is
initialized with tire pressures which are not the
specified values.
(c) The average life of the grommet of the tire pressure
warning antenna and receiver is approximately 5
years, at which time it must be replaced. Retighten
the valve nut if the valve is leaking air, if it is less
than 5 years old, and there is no problem with the
grommets.
(d) After removing and installing the ECU or a sensor,
output a diagnosis code and check that it is a
normal code.
3. FUNCTION OF COMPONENTS
Components Function
Tire pressure warning antenna and receiver • Combined as a single unit with a disc wheel air valve, it measures
tire pressure and temperature, and transmits an ID number for
measurement value and identification
• Battery is built into valve
Tire pressure warning antenna and receiver Receives necessary signals from tire pressure warning antenna and
receiver and transmits them to tire pressure warning ECU
Tire pressure warning ECU • Receives signal from receiver and identifies it as vehicle's own
signal.
• If measurement value is equal to or lower than specified value, it
transmits a signal so that the air pressure warning light on
combination meter turns on.
Tire pressure warning light Located in the combination meter, it informs driver of lowered tire air
pressure and system failure

(c) Test mode
(1) By switching from normal mode to test mode
(input signal check), you can inspect the tire
pressure monitor receiver, each tire pressure
warning valve and transmitter and vehicle speed
sensor (see page TW-12).
3. CHECK TIRE PRESSURE WARNING LIGHT
(a) Turn the ignition switch ON.
(b) Check that the tire pressure warning light turns on
for 3 seconds.
If the warning check result is not normal, proceed to
the troubleshooting for the tire pressure warning
light circuit.
4. TIRE PRESSURE WARNING LIGHT CHART

The table below indicates the state of the tire pressure
warning light after the ignition switch is turned ON.
