PROCEDURE
BEFORE REGISTRATION
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.
In case of tire pressure warning ECU and receiver replacement:
Read the registered transmitter IDs that are stored in the old ECU using the GTS and write them down.
If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning ECU 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.
*1 | Tire Pressure Warning Valve and Transmitter | *2 | Transmitter ID (7-digit Number) |
REGISTER TRANSMITTER ID (USING GTS)
Tech Tips
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 tire pressure to the specified value.
Turn the engine switch off.
Connect the GTS to the DLC3.
Turn the engine switch on (IG) and the GTS on.
Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

Perform the procedure according to the display on the GTS.
CONFIRMATION OF TRANSMITTER ID REGISTRATION
Note
It may take a few 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 C2124/24.
If the transmitter 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 transmitter IDs have been registered correctly.
If the tire pressure values are not displayed after a few minutes, the transmitter IDs may be incorrect or the system may have a malfunction.
After all transmitter 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 illuminates. 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.
Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tech Tips
*1: It may take a few 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 C2124/24.
Rapidly reduce the inflation pressure of each tire at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds, and check that the "ID Tire Inflation Pressure" data is updated and that the actual tire inflation pressures are displayed.
After confirming that all of the tire inflation pressure values (except the compact spare tire) have been updated, adjust the tire inflation pressure to the specified value, press the tire pressure warning reset switch and perform initialization.
