Register Transmitter IDS (Using The Techstream)

NOTE: The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire onto the wheel. Therefore, make a note of the transmitter ID before installing the tire.

NOTE: In case of tire pressure warning ECU and receiver 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, 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 previously registered IDs will be cleared from memory when the registration is completed. If the ID registration step is not completed within 300 seconds, ID registration will be canceled.

Set the air pressure of all tires to the specified value(s).
Turn the ignition switch OFF
Connect the Techstream to the DLC3.
Turn the ignition switch to ON and the Techstream ON.
Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
Perform the procedure displayed on the Techstream.

It may take up to a few 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 C2124/24.
If the IDs have not been registered, DTC C2171/71 is stored in the tire pressure warning ECU and receiver 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 screen.
After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.
