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 a tire pressure warning ECU.

Prepare all transmitter ID data before starting registration.

1. 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 (See TIRE PRESSURE WARNING SYSTEM ).
   2. When replacing a tire pressure warning valve and transmitter:
      • Make a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
      Fig 3: Identifying 7-Digit Number (Transmitter ID) On Tire Pressure Warning Valve And Transmitter

      Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      NOTE:

      • The transmitter ID is written on the tire pressure warning valve and transmitter. It will not be 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.
      • When one tire pressure warning valve and transmitter is replaced, the transmitter IDs for all the tire pressure warning valve and transmitters must be re-registered. Before registering the transmitter ID of the new tire pressure warning valve and transmitter, check the Data List and record the all of the transmitter IDs that are already registered.

1. Set all tire pressures to the specified value(s) (See TIRE PRESSURE WARNING SYSTEM ).
2. Turn the ignition switch off.
3. Connect the Techstream to the DLC3.
4. Turn the ignition switch to ON.
5. Turn the Techstream on.
6. Enter the following menus: Chassis / Tire Pressure Monitor/ Utility / ID Registration.
7. Follow the ID Registration steps displayed the Techstream screen.
8. Confirmation of transmitter ID registration.
   1. Enter the following menus: Chassis / Tire Pressure Monitor/ Data List.
   2. Read the "ID Tire Inflation Pressure" values.
   3. Confirm that the tire pressure data of all tires are displayed on the Techstream.
      NOTE:

      • It takes about 2 or 3 minutes to display the updated 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 (See DTC C2121/21 NO SIGNAL FROM TRANSMITTER ID1; DTC C2122/22 NO SIGNAL FROM TRANSMITTER ID2; DTC C2123/23 NO SIGNAL FROM TRANSMITTER ID3; DTC C2124/24 NO SIGNAL FROM TRANSMITTER ID4; DTC C2181/81 TRANSMITTER ID1 NOT RECEIVED (TEST MODE DTC); DTC C2182/82 TRANSMITTER ID2 NOT RECEIVED (TEST MODE DTC); DTC C2183/83 TRANSMITTER ID3 NOT RECEIVED (TEST MODE DTC); DTC C2184/84 TRANSMITTER ID4 NOT RECEIVED (TEST MODE DTC) ).
      • 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 a few 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) 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 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.

1. Adjust all tire pressures to the standard tire inflation pressure, as indicated on the tire and loading information label on the vehicle.
2. Turn the ignition switch to ON.
3. Push and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
