Abnormally High Temperature
1. Turn the ignition switch to LOCK (0).
2. Make sure the tires have cooled down.
NOTE: An abnormal rise in the internal temperature
of the tires can be caused by
• Excessive braking
• Failure to release the parking brake (rear tires
only)
• Leaving the vehicle running while parked (front
tires only)
• Improper assembly of a wheel and tire
3. Test-drive the vehicle at 45 km/h (28 mph) or more
for at least 1 minute.
The system is OK at this time. Clear the DTC
with the HDS.
Go to step 4.
4. Check for DTCs with the HDS.
5. Note the tire pressure sensor(s) number by the
indicated DTC.

No. 4
6. 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).
7. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR
TEMPERATURE in the TPMS DATA LIST with the
HDS.
Replace the appropriate tire pressure sensor
(see page 18-76).
Go to step 8.
8. Clear the DTC with the HDS.
9. Test-drive the vehicle at 45 km/h (28 mph) or more
for at least 1 minute.
10. Check for DTCs with the HDS.
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
If any other DTCs are indicated, troubleshoot
the appropriate DTC. If no DTC are indicated, the
system is OK at this time.
Does the T PMS indicator go of f ?
Is 80 °C ( 17 6 °F ) or mor e indicated?
Is DT C 21, 22, 23, or 24 indicated?

Tire Pressure Sensor Low
Battery Voltage
NOTE: This problem occurs when the temperature
around the sensor is
40 °C (
40 °F) or less. Note that
the diagnosis must be made in a place where ambient
temperature is
40 °C (
40 °F) or more.
1. Test-drive the vehicle at 45 km/h (28 mph) or more
for at least 1 minute.
The system is OK at this time. Clear the DTC
with the HDS.
Go to step 2.
2. Check for DTCs with the HDS.
3. Note the tire pressure sensor(s) number by the
indicated DTC.

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. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4
PRESSURE SENSOR TRANSMITTER BATTERY in
the TPMS DATA LIST with the HDS.
Replace the appropriate tire pressure sensor
(see page 18-76).
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.

NOTE: Inspect for an aftermarket electrical device(s)
(such as an inverter, battery charger, etc) interfering
with the RF signal from the sensors when driving the
vehicle.
1. Turn the ignition switch to ON (II).
2. Make sure all four wheels are TPMS wheels with
the mounted tire pressure sensors.
Go to step 3.
Install the TPMS wheel, and then memorize
the pressure sensor ID with the HDS (see page
18-52).
3. Turn the ignition switch to ON (II).
4. Check for DTCs with the HDS.
5. Note the tire pressure sensor(s) number by the

Go to step 7.
Check for an aftermarket electrical device(s)
interfering with the RF signals from the sensors. If
there are no electrical devices causing interference,
replace the appropriate tire pressure sensor
(see page 18-76).
7. Turn the ignition switch to LOCK (0), and wait 5
minutes or more.
8. Test-drive the vehicle at 45 km/h (28 mph) or more
for at least 1 minute.
9. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4
PRESSURE SENSOR TRANSMITTER STATUS in
the TPMS DATA LIST with the HDS.
The system is OK at this time. Clear the DTC
with the HDS.
Replace the appropriate tire pressure sensor
(see page 18-76).
