INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION - (Continued)
8. DESCRIPTION OF CODE REGISTRATION (Tire Pressure Warning System)
It is necessary to register the transmitter IDs in the tire pressure warning ECU when replacing a tire pressure warning valve and transmitter and/or tire pressure warning ECU.
Prepare all transmitter ID data before starting registration.
(a) Before registration
(1) When replacing the tire pressure warning ECU:
* 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 valve and transmitters Service Precautions.
(2) When replacing a tire pressure warning valve and transmitter:
* 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 onto the wheel. Therefore, take a note of the transmitter ID before installing the tire onto the wheel.
9. REGISTER TRANSMITTER ID (USING TECHSTREAM) (Tire Pressure Warning System)
(a) Set the air pressure of all tires to the specified value Service Precautions.
(b) Turn the power switch off.
(c) Connect the Techstream to the DLC3.

(g) Confirmation of transmitter ID registration.
(1) Enter the menu items in this order: Chassis / Tire Pressure Monitor / Data List.
(2) Read the "ID Tire Inflation Pressure" values.
(3) Confirm that the data of tire pressure of all tires are displayed on the screen.
NOTICE:
* It may take up to about 2 or 3 minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25 C2121.
* 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 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.
