REGISTRATION

1. DESCRIPTION OF CODE REGISTRATION

It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire
pressure warning valve and transmitter and/or tire pressure warning ECU.

Prepare all transmitter ID data before starting registration.

a. Before registration

1. In case of tire pressure warning ECU replacement:



Read the registered transmitter IDs that are stored in the old ECU using the Techstream
and note them down.



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 (See TIRE
PRESSURE WARNING SYSTEM ).

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.

2. REGISTER TRANSMITTER ID

a. Set the tire pressure of all 4 tires to the specified value(s) (See TIRE PRESSURE WARNING

SYSTEM ).

b. Turn the ignition switch off.

c. Connect the Techstream to the DLC3.

d. Turn the ignition switch to ON and the Techstream on.

e. Enter the following menus: Chassis/Tire Pressure Monitor/Utility/ID Registration.

f. Perform the following procedures displayed on the screen.

g. Confirmation of transmitter ID registration.

1. Enter the following menus: Chassis/Tire Pressure Monitor/Data List.

2. Read the "ID Tire Inflation Pressure" values.

3. Confirm that the data of tire pressure of all 4 tires are displayed on the screen.

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:



It may take up to about 5 to 6 minutes to update the tire
pressure data. If the values are not displayed after several
minutes, perform troubleshooting according to the
inspection procedure for DTCs C2121/21 to C2124/24 (See

DTC C2121/21, C2122/22, C2123/23, C2124/24, C2181/81,
C2182/82, C2183/83, C2184/84: NO SIGNAL FROM
TRANSMITTER ID1; NO SIGNAL FROM TRANSMITTER ID2;
NO SIGNAL FROM TRANSMITTER ID3; NO SIGNAL FROM
TRANSMITTER ID4; TRANSMITTER ID1 NOT RECEIVED

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 (See
REGISTRATION ).

b. Before initialization

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

WARNING SYSTEM ).

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.

(TEST MODE DTC); TRANSMITTER ID2 NOT RECEIVED
(TEST MODE DTC); TRANSMITTER ID3 NOT RECEIVED
(TEST MODE DTC); TRANSMITTER ID4 NOT RECEIVED
(TEST MODE DTC)

).



If the IDs have not been registered, DTC C2171/71 is set in
the tire pressure warning ECU after 3 minutes or more.



If normal pressure values are displayed, the IDs have been
registered correctly.



If the tire pressure values are not displayed after several
minutes, the IDs may be incorrect or the system may have
a malfunction.



After all IDs are registered, DTC C2126/26 (Transmitter ID
not Received in Main Mode) is set in the tire pressure
warning ECU and the tire pressure warning light blinks for
1 minute and then comes on. When the tire pressure
warning ECU successfully receives information from all
the transmitters whose IDs are stored in the ECU, DTC
C2126/26 is deleted and the tire pressure warning light
goes off.

NOTE:

Make sure the tires are cooled down.

NOTE:



The initialization is normally completed within 5 to 6 minutes.



If the initialization has not been completed successfully, DTC
