Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION (2008 Sequoia) |
INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
-
Before delivery of a new vehicle.
-
After rotating the tires on vehicles whose front and rear tire inflation pressure standard values are different.
-
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
.
(b) Before initialization
(1) Set the air pressure of all tires to the specified value
.
NOTICE:
Make sure that 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 turn 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/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:
-
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
