8. REGISTRATION RELATED TO TIRE PRESSURE WARNING DESCRIPTION OF CODE REGISTRATION It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing a tire pressure warning valve and transmitter and/or the tire pressure warning ECU: Prepare all transmitter ID data before starting registration. Before registration 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 the 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. In case of tire pressure warning valve and transmitter replacement: Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter. 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 to the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter. REGISTER TRANSMITTER ID (USING TECHSTREAM) Set the air pressure of all tires to the specified value(s). Turn the engine switch off. Connect the Techstream to the DLC3. Turn the engine switch on (IG) and the Techstream on. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration. Perform the procedures displayed on the Techstream. HINT: The previously registered IDs will be cleared from the memory when the registration is completed. Registration can be performed during initialization. However, the initialization will be canceled when the registration is started. If this step is not completed within 300 seconds, this mode will be canceled. Confirmation of transmitter ID registration: Enter the following menus: Chassis / Tire Pressure Monitor / Data List. Read the "ID Tire Inflation Pressure" values. Confirm that the tire pressure data of all tires (including the spare tire) is displayed on the Techstream screen. NOTE: 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. If the IDs have not been registered, DTC C2171/71 is 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. The tire pressure information reception condition can also be confirmed through the multi-information display tire pressure display screen. After all IDs are registered, DTC C2126/26 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 and receiver successfully receives information from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.
