INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
Before delivery of a new vehicle.
After replacement of the tire pressure warning ECU*.
After replacement of the tire pressure warning valve and transmitter*.
HINT:
*: Perform initialization after the transmitter ID registration is completed 2010 MY Tundra [04/2009 - ]; TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: REGISTRATION .
(b) Before initialization
(1) Set the tire pressure of all tires to the specified value(s) 2010 MY Tundra [04/2009 - ]; TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: PRECAUTION .
NOTICE:
Make sure the tires are cooled down.
2. INITIALIZATION PROCEDURE
(a) Turn the ignition switch to ON.
(b) Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
(c) Turn the ignition switch off.
(d) Connect the Techstream to the DLC3.
(e) Turn the ignition switch to ON and the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(g) Confirm that the tire pressure data of all tires are displayed on the Techstream screen in order to check the completion.
NOTICE:
The initialization is normally completed within 5 to 6 minutes.
If the initialization has not been completed successfully, DTC C2177/77 is set after the vehicle is driven for 20 minutes or more.
The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.

ID1 Tire Inflation Pressure
ID1 tire inflation pressure /
min.: Absolute pressure / 100 kPa (1 kgf/cm 2 , 14 psi), Relative pressure / 0 kPa (0 kgf/cm 2 , 0 psi)
max.: Absolute pressure / 449.35 kPa (4.5 kgf/cm 2 , 63 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm 2 , 51 psi)
Actual tire inflation pressure
If 100 kPa (1 kgf/cm 2 , 14 psi) for the absolute pressure or 0 kPa (0 kgf/cm 2 , 0 psi) is displayed for the relative pressure, the data has not been received.*

max.: Absolute pressure / 449.35 kPa (4.5 kgf/cm 2 , 63 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm 2 , 51 psi)
Actual tire inflation pressure
If 100 kPa (1 kgf/cm 2 , 14 psi) for the absolute pressure or 0 kPa (0 kgf/cm 2 , 0 psi) is displayed for the relative pressure, the data has not been received.*
ID3 Tire Inflation Pressure
ID3 tire inflation pressure /
min.: Absolute pressure / 100 kPa (1 kgf/cm 2 , 14 psi), Relative pressure / 0 kPa (0 kgf/cm 2 , 0 psi)
max.: Absolute pressure / 449.35 kPa (4.5 kgf/cm 2 , 63 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm 2 , 51 psi)
Actual tire inflation pressure
If 100 kPa (1 kgf/cm 2 , 14 psi) for the absolute pressure or 0 kPa (0 kgf/cm 2 , 0 psi) is displayed for the relative pressure, the data has not been received.*
ID4 Tire Inflation Pressure
ID4 tire inflation pressure /
min.: Absolute pressure / 100 kPa (1 kgf/cm 2 , 14 psi), Relative pressure / 0 kPa (0 kgf/cm 2 , 0 psi)
max.: Absolute pressure / 449.35 kPa (4.5 kgf/cm 2 , 63 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm 2 , 51 psi)
Actual tire inflation pressure
If 100 kPa (1 kgf/cm 2 , 14 psi) for the absolute pressure or 0 kPa (0 kgf/cm 2 , 0 psi) is displayed for the relative pressure, the data has not been received.*
HINT:
The initialization is complete when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.
*: It may take up to about 5 to 6 minutes to update the tire pressure data. If the values are not displayed after about 5 to 6 minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 2010 MY Tundra [04/2009 - ]; TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2121/21-C2124/24,C2181/81-C2184/84; No Signal from Transmitter ID1 .
