1. Set the tire pressure of all wheels (including spare tire) to the specified value.

2. Connect the hand-held tester to DLC3.

3. Turn ignition switch to ON position.

4. Select "DATA LIST" mode on the hand-held tester.

5. Confirm the "TIREPRESS" values are displayed on the hand-held tester screen.

TPMS RESET - PROCEDURE 16

Tire Pressure Monitor Warning Light

When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure
and adjust as necessary. The warning light should turn off within a few minutes. If the warning light is still on
even though the tire pressure is correctly adjusted, the tire could be punctured. Repair as necessary. If the
warning light turns on within several hours after adjusting the tire pressure, the tire may have a slow air leak. If
the warning light is still on or blinks, there is a malfunction in the TPM system. See appropriate manufacturer
service information.

Under the following conditions, the system may not function properly:



Facilities or devices that use similar radio wave frequencies are located in the vicinity of the vehicle.



A radio device of similar frequency is used near the vehicle.



A lot of snow or ice is stuck to the vehicle, especially around the wheels or wheel housings.



Tires and wheels are installed that are not equipped with a tire pressure sensor.



Snow tires or tire chains are used.



The battery of the sensor has been depleted.



Wheels other than manufacturer factory wheels are used. If any other wheels than the specified ones are

NOTE:

When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the
sensor ID must be memorized by the tire pressure monitor ECU. See TIRE
PRESSURE SENSOR REGISTRATION.

NOTE:

If the negative battery terminal is disconnected, initialize the following system
after the terminal is reconnected: power window control system. Refer to
owner's manual or appropriate manufacturer service information.

NOTE:

The tire pressure warning light may turn on due to natural causes such as
natural air leaks or tire pressure changes caused by temperature. In this case,
adjusting the tire pressure will turn off the warning light.

NOTE:

If warning light turned on due to very low outside temperatures (such as in
winter) causing decreases in tire pressure, adjust pressure to a higher pressure
suitable to cold conditions. Tire pressure decreases by about 1.45 psi (10 kPa)
for every 18°F (10°C) drop in ambient temperature.

used, the system may not function properly because the radio waves are differently transmitted from the
tire pressure sensor.



Depending on the tire type, the system may not function properly even though the specified wheels are
used.



Using a different type of tire in combination with genuine tires.

Tire Pressure Sensor Registration

NOTE:

When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the
sensor ID must be memorized by the tire pressure monitor ECU. To perform this
procedure, a Toyota intelligent tester called Techstream must be used. It is not
necessary to register the sensor ID(s) when only tire rotation is performed.

NOTE:

Before beginning registration process on vehicles where tire pressure sensors
have not been replaced, retrieve sensor transmitter ID(s) using intelligent tester
or by reading the ID on the tire pressure sensor. If sensor is being replaced with
a new one, make a note of the 7-digit number (transmitter ID) before installation,
as it cannot be seen after sensor is installed. See Fig. 31.

1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.

2. Connect the intelligent tester to DLC3. See Fig. 18.

3. Turn the Tachstream scan tool on and the ignition switch to ON position.

4. Using the scan tool, select "Chassis".

5. Select "Tire Pressure Monitor".

6. Select "Utility".

7. Select "ID Registration"

8. Perform the procedure displayed on the scan tool.

9. Confirm the tire pressure sensor's IDs are registered.

10. Repeat steps 4 & 5, then select "Data List".

11. Confirm the tire pressure values are displayed for all 4 tires.

NOTE:

Tire pressure sensor IDs that were previously registered will be deleted
from the memory when registration is completed.

NOTE:

It may take up to 2 or 3 minutes to update the tire pressure data. If tire
pressure values do not display after 2 or 3 minutes, troubleshoot DTCs
C2121/21 to C2124/24.

NOTE:

If the ID(s) have not been registered, DTC C2171/71 is set in the tire
pressure monitor ECU after 3 minutes or more.
