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 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 Service Precautions.
(2) 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 the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.

2. REGISTER TRANSMITTER ID

- 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's tire pressure display screen.
- After all IDs are registered, DTC C2126/26 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.
