System Description (cont’d)
Control Unit
(With Radio Frequecy Antenna)
Tire Pressure Sensor
(Sensor-transmitter with acceleration sensor)
 When the vehicle is traveling more than 45 km/h (28 mph), an RF (radio frequency) band wave signal is transmitted
from each tire pressure sensor to the control unit.
 When the wheels rotate, and the tire pressure sensors momentum is detected, switching them from sleep mode to normal function (awake) mode. After the vehicle is stationary for 5 minutes, the sensors switch from normal
function mode back to sleep mode to extend their battery life.
 Each tire pressure sensor has its own ID to prevent jamming by similar systems on other vehicles. After memorizing all the sensor IDs, the control unit recognizes only those specific signals.
 An ID cannot be memorized automatically. The control unit knows which ID belongs to each tire pressure sensor. This recurring ID confirmation prevents any confusion in the system as a result of normal tire rotation.
NOTE: Be careful not to bend the brackets on the TPMS control unit: Misalignment of the control unit could interfere
with sending and receiving signals.

Symptom Troubleshooting
NOTE: Check for gauge DTCs with the HDS (see page
22-3). If gauge DTCs are stored, troubleshoot those
DTCs first.
1. Turn the ignition switch to ON (II).
2. Check the low tire pressure indicator for several seconds when the ignition switch is turned ON (II).
Go to step 3.
Do the troubleshooting for the gauge control
module (see page 22- 241). If necessary, substitute a
known-good gauge control module (see page
22-277), and recheck.
3. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
4. Stop the vehicle, and lower the pressure in each tire until the low tire pressure indicator comes on
(see table).
NOTE: Reinflate the tire before continuing to the next tire.
 After noting whether the low tire pressure indicator came on, make sure it goes off when
you reinflate the tire before proceeding to the
next tire.
 If 5 minutes has passed since finishing the last test-drive, reactivate the appropriate tire
pressure sensor using the TPMS sensor initializer
tool (see page 18-53).
16 inch wheels 175 kPa (1.8 kgf/cm , 25 psi)
17 inch wheels 183 kPa (1.9 kgf/cm , 27 psi)
The system is OK at this time.
Go to step 5. 5. Do the tire pressure sensor location procedure to
determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
Go to step 6.
Check that the tire pressure sensor is properly
mounted. If necessary, replace the appropriate tire
pressure sensor (see page 18-76).
6. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS,
and compare with the actual measured tire
pressure.
Go to step 7.
Replace the appropriate tire pressure sensor
(see page 18-76).
7. Turn the ignition switch to LOCK (0).

1. Raise the vehicle, and support it with safety stands in the proper locations (see page 1-11).
2. Remove the wheel with the faulty sensor.
3. Remove the tire valve stem cap and the valve stem core, to deflate the tire.
4. Remove any balance weights, and then break the bead loose from the wheel with a commercially
available tire changer (A).
Note these items to avoid damaging the tire
pressure sensor: Do the outside of the wheel first.
 Position the wheel as shown so the valve stem (B) is 90 degrees from the bead
breaker (C) as shown.
 Do not position the bead breaker of the tire changer too close to the rim. 5. Position the wheel so the tire machine (A) and tire
iron (B) are next to the valve stem (C), and will
move away from it when the machine starts. Then
remove the tire from the wheel.
6. Remove the valve stem nut (A) and the washer (B), then remove the tire pressure sensor with the valve
stem (C) from the wheel.
NOTE: Check the nut and the washer, If they have
deterioration or damage, replace then with new
ones during reassembly.

7. Remove and discard the valve stem grommet (A) from the tire pressure sensor (B).
NOTE: The valve stem grommet might stay in the wheel; make sure you remove it.
 Always use a new valve stem grommet whenever the tire pressure sensor has been
removed from the wheel or when replacing the
tire. NOTE:
 Use only wheels that have a ‘‘TPMS’’ stamp (A) on them.
 The vehicle may be equipped with one of the three types of wheels.

1. Before installing the tire pressure sensor, clean the
mating surfaces on the sensor and the wheel.
2. Install the tire pressure sensor (A) and the washer (B) to the wheel (C), and tighten the valve stem nut
(D) finger tight. Make sure the pressure sensor is
restingonthewheel.
NOTE: Install the tire pressure sensor so that
sensor housing surface (E) should not exceed
protrusion (F) of wheel to prevent the sensor
housing from being caught on the bead of the tire
when assembling the tire.
3. Tighten the valve stem nut to the specified torque while holding the tire pressure sensor.
NOTE: Do not use air or electric impact tools to tighten a valve stem nut.
 Do not twist the tire pressure sensor to adjust its position with the wheel, as this will damage or
deform the valve stem grommet. 4. Lube the tire bead sparingly with a paste-type tire
mounting lubricant, and position the wheel so the
tire machine (A) and tire iron (B) are next to the
valve stem (C) and will move away from it when
the machine starts. Then install the tire onto the
wheel.
5. With a dry air source, inflate the tire to 300 kPa (3.1 kgf/cm , 44 psi) to seat the tire bead to the rim,
then adjust the tire pressure (see page 18-5), then
install the valve stem cap.
NOTE: Make sure the tire bead is seated on both
sides of the rim uniformly.
6. Check and adjust the wheel balance, then install the wheels on the vehicle.
7. Remove the jack stands, and lower the vehicle. Torque the wheel nuts to specification.
8. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).
