necessary, substitute a known-good TPMS control
unit (see page 18-75), and recheck.
Repair open in the wire between the TPMS
control unit and the ECM/PCM. 1. Turn the ignition switch to ON (II).

4. 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 5.
Check that the tire pressure sensor is properly
mounted. If necessary, replace the appropriate tire
pressure sensor (see page 18-76).
5. Clear the DTC with the HDS.
6. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
7. Check for DTCs with the HDS.
Replace the appropriate tire pressure sensor
(see page 18-76) and recheck. If DTCs are still
present, substitute a known-good TPMS control
unit (see page 18-75), and recheck.

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).

NOTE: Make sure the TPMS control unit mounting
bracket is not bent or twisted as this may affect its
communication with the tire pressure sensors.
1. Turn the ignition switch to LOCK (0).
2. Remove the driver’s dashboard undercover (see page 20-103).
3. Disconnect the TPMS control unit connector (A).
4. Remove the TPMS control unit (B) from the bracket (C).
NOTE: To disconnect the TPMS control unit from its
bracket, insert a small flat-tipped screwdriver
between the TPMS control unit and the bracket
shown in (D) to release the hook, then slide out the
TPMS unit.
5. Replace the bracket if necessary. 6. Install the new TPMS control unit in the reverse
order of removal.
NOTE: Make sure the TPMS control unit is properly
installed. You will hear a click when the TPMS
control unit is securely mounted on the bracket.
7. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).

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).
