DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the tire pressure warning antenna and 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 value is less than this threshold, the warning light in the combination meter comes on. The tire pressure warning ECU stores a DTC when the tire pressure warning valve and transmitter 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.

Tire pressure warning valve and transmitters stop transmitting signals |
|
HINT:
It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.
CAUTION / NOTICE / HINT
NOTICE:
It is necessary to perform initialization (See page
![2016 - 2020 MY Sienna [12/2015 - ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION](/t3Portal/stylegraphics/info.gif)
) after registration (See page
) of the transmitter IDs into the tire pressure warning ECU if the ECU and/or any of the valve and transmitters have been replaced.
PROCEDURE
|
1. |
PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF ALL WHEELS |
(a) Set the tire pressure to the specified value (See page
).
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(g) Check the values by referring to the table below.

Diagnostic Note |
|---|---|---|---|
|
ID1 Tire Inflation Pressure |
ID1 tire inflation pressure/ min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID2 Tire Inflation Pressure |
ID2 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID3 Tire Inflation Pressure |
ID3 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID4 Tire Inflation Pressure |
ID4 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
HINT:
*: It may take up to 5 or 6 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (See page
).
(h) Rapidly release the pressures from each wheel by approximately 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.
(i) Check that each tire pressure data displayed on the Techstream screen has changed.
OK:
Each tire pressure data displayed on the Techstream screen will change to the value of the tire pressure.
NOTICE:
- It takes up to 5 or 6 minutes to display the updated tire pressure data.
- When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°(including the spare tire). Then rapidly release the tire pressure and recheck the data.
(j) After confirming that all of the tire pressure data displayed on the Techstream screen has changed, set the tire pressure to the appropriate specified values.
HINT:
If the tire pressure data displayed on the Techstream screen has not changed after rechecking, perform the inspection for malfunctions in transmission or reception function (See page
).
