Toyota Tundra. Manual — part 10



If reading stored transmitter IDs is impossible due to malfunctions of components such
as the tire pressure warning antenna and receiver, remove the tires from the wheels and
check the IDs located on the tire pressure warning valves and transmitters.

2. In case of tire pressure warning valve and transmitter replacement: Take a note of the 8 digit

number (transmitter ID) written on the tire pressure warning valve and transmitter.

8. 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.

b. Before initialization

1. Set the tire pressure of all tires to the specified value(s).

9. INITIALIZATION PROCEDURE

a. Turn the ignition switch to ON.

NOTE:

The transmitter ID is written on the tire pressure warning valve
and transmitter. It will be unable to be read after installing the
tire pressure warning valve and transmitter on the tire and
wheel. Therefore, take a note of the transmitter ID before
installing the tire pressure warning valve and transmitter.

NOTE:

Make sure the tires are cooled down.

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.

NOTE:



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.

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

10. CLEAR ZERO POINT CALIBRATION DATA

a. Connect the Techstream to the DLC3.

b. Turn the ignition switch ON.

c. Operate the Techstream to erase the codes (select "Reset Memory").

HINT:

Refer to the Techstream operator's manual for further details.

11. PERFORM ZERO POINT CALIBRATION OF MASTER CYLINDER PRESSURE SENSOR

AND DECELERATION SENSOR

a. Enter Test Mode.

1. Turn the ignition switch OFF.

2. Check that the shift lever is in parking or neutral and apply the parking brake.

3. Connect the Techstream to the DLC3.

4. Turn the ignition switch ON.

5. Set the Techstream to test mode (select "Test Mode").

HINT:

Refer to the Techstream operator's manual for further details.

b. Obtain the zero points of the master cylinder pressure sensor and deceleration sensor.

1. Keep the vehicle stationary on a level surface for 1 second or more.

inspection procedure for DTCs C2121/21 to C2124/24.

NOTE:



While obtaining the zero point, do not vibrate the vehicle by tilting,
moving or shaking it and keep it stationary. (Do not start the engine.)



While obtaining the zero point, do not depress the brake and
accelerator pedal.



Obtain the zero point on a level surface (with an inclination of less
than 1°).

CAUTION: Application of the parking brake is not necessary for

entering test mode. However, apply the parking brake for
safety.
