• When jacking up the front wheels first, make sure
wheel chocks are behind the rear wheels.
• When jacking up the rear wheels first, make sure
wheel chocks are in front of the front wheels.
(f) When jacking up only the front or rear wheels of the
vehicle:
• Before jacking up the front wheels, place wheel

GENERAL MAINTENANCE
(2006/01- )
1. INSPECT STEERING LINKAGE AND GEAR HOUSING
(a) Check the steering wheel free play.
(b) Check the steering linkage for looseness or
damage.
(1) Check that the tie rod ends do not have
excessive play.
(2) Check that the dust seals and boots are not
damaged.
(3) Check that the boot clamps are not loose.
(4) Check that the steering gear housing is not
damaged.
(5) Check that the connectors are properly
connected to the steering gear housing.
2. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(1) Jack up the front of the vehicle and place
wooden blocks with a height of 180 to 200 mm
(7.09 to 7.87 in.) under the front tires.
(2) Lower the vehicle until the front coil spring has
about half its ordinary load. Place stands under
the vehicle for safety.

(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

REGISTRATION
1. IN CASE OF TIRE PRESSURE WARNING ECU
REPLACEMENT
(a) Read ID stored in the old ECU using the intelligent
tester.
2. IN CASE OF TIRE PRESSURE WARNING VALVE AND
TRANSMITTER AND/OR TIRE PRESSURE WARNING
ECU REPLACEMENT
(a) Read the ID written on the tire pressure monitor
valve.
3. REGISTER TRANSMITTER ID
NOTICE:
It is necessary to register the transmitter ID in the
tire pressure warning ECU when replacing the tire
pressure warning valve and transmitter and/or tire
pressure warning ECU.
(a) Prepare all of the transmitter ID data before starting
registration.
HINT:
• Read the registered transmitter IDs that are
stored in the ECU using the intelligent tester and
make a note of them.
• If reading stored transmitter IDs is impossible
due to malfunctions of components such as the
tire pressure warning antenna and receiver,
remove the tires from the wheels and check the
IDs located on the tire pressure warning valves
and transmitters (see page TW-60).
• When replacing the tire pressure warning valves
and transmitters, make a note of the IDs written
on the tire pressure warning valves and
transmitters.
(b) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(c) Turn the ignition switch ON.
(d) *1: Read and write down the ID (ID1 to ID5) by
using the DATA LIST.

(b) Connect the intelligent tester (with CAN VIM ) to the
DLC3.
(c) Turn the ignition switch ON.
(d) Select "SIGNAL CHECK" mode on the intelligent
tester (with CAN VIM ) (see page TW-12).
(e) Confirm that the transmitter IDs and tire pressure
data for all the tires are displayed on the intelligent
tester screen.
NOTICE:
• It may take up to 1 minute to update the tire
pressure data.
• If the IDs have not been registered, DTC
C2171/71 is set in the tire pressure warning
ECU after approximately 60 minutes.

TW–28TIRE AND WHEEL – TIRE PRESSURE WARNING SYSTEM
TW
DESCRIPTION
The tire pressure warning valve and transmitter that is installed in the tires and wheels measures the air
pressure of the tires. The measured values are transmitted to the tire pressure warning receiver on the
body as radio waves and then sent to the tire pressure warning ECU. The ECU compares the measured
air pressure values with the air pressure threshold. When the measured air pressure values are less than
this threshold, the warning light in the combination meter turns on.
The tire pressure warning ECU stores a DTC when the tire pressure monitor valve stops transmitting
signals. At this time, forcibly transmit the signals by releasing the tire pressure rapidly. The stored DTC is
cleared when the signal transmission is resumed.
HINT:
It is necessary to perform the procedure to identify the tire pressure monitor valve that is malfunctioning
because it cannot be identified by the output DTC.

(e) Rapidly release the pressure from each wheel by
approximately 40 kPa (0.4 kgf/cm
2, 5.8 psi) for 30
seconds or more.
(1) Check that each tire pressure data displayed on the
intelligent tester screen changes.
OK:
The tire pressure data displayed on the
intelligent tester screen changes with the
value of the tire pressure.
NOTICE:
• It may take up to 1 minute to display the
updated tire pressure data.
• When the TIREPRESS data (IDs 1 to 5)
changes, reset the tire pressure of the tires to
the specified value, rotate the tires 90 to 270

and recheck.
(2) After confirming that the tire pressure data displayed
on the intelligent tester screen has changed, set the
pressure of each tire to the specified value.
Standard pressure:
220 kPa (2.2 kgf/cm
2, 32 psi)
HINT:
If the tire pressure data displayed on the intelligent
tester screen has not changed after rechecking, go
to the troubleshooting procedures of DTCs C2121/
21 to C2125/25 which indicate transmission or
reception malfunctions (see page TW-28).
