Registration (from 12/2010)

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: 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.

2. PREPARATIONS BEFORE REGISTRATION

(a) If replacing the tire pressure warning ECU:

(1) Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tire Pressure Monitor:





HINT
*1: Displayed only when the ID No. is not registered.

(2) 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 valve and transmitters Precaution (from 12/2010).

(b) If replacing the tire pressure warning valve and transmitter:

(1) When replacing the tire pressure warning valve and transmitters, note down the IDs written on the tire pressure warning valve and transmitters.

(2) Take a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.





NOTICE:
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.

3. REGISTER TRANSMITTER ID

(a) Set the air pressure of all the wheels to the specified value Precaution (from 12/2010).

(b) Make sure that the ignition switch is off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch on (IG).

(e) Turn the Techstream on.

(f) Perform the transmitter ID registration. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

(g) Input the transmitter IDs (ID1 to ID5) using the Techstream and transmit them to the tire pressure warning ECU.

(h) The "ID Registration is complete" is displayed on the Techstream display.

HINT
* The tire pressure warning light will continue to blink until the tire pressure warning ECU receives the input ID signals.
* The previously registered IDs will be deleted from the memory when the registration is completed.
* Registration can be performed during initialization. However, the initialization will be cancelled when the registration is started.

4. CONFIRMATION OF TRANSMITTER ID REGISTRATION

(a) Make sure that the ignition switch is off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch on (IG).

(d) Turn the Techstream on.

(e) Confirm that the data of tire pressure of all wheels are displayed on the Techstream display. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tire Pressure Monitor:





NOTICE:
* *1: It may take about 2 or 3 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 C2125/25 Tire Pressure Monitoring (from 12/2010).
* If the IDs have not been registered, DTC C2171/71 will be stored 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 a few 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 stored 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 radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.
