Tire Pressure Sensor Registration

NOTE: When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU prior to system initialization. To perform this procedure, the Techstream must be used. It is not necessary to register the sensor ID(s) when only a tire rotation is performed.
NOTE: Before beginning registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmitter ID(s) using Techstream or by reading the ID on the tire pressure sensor itself. If sensor is being replaced with a new one, make note of the 7-digit number (transmitter ID) before installation, as it cannot be seen after sensor is installed. See Figure.
  1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
  2. Turn ignition switch OFF.
  3. Connect Techstream to DLC3.
  4. Turn ignition switch ON.
  5. Turn Techstream ON.
  6. Perform the transmitter ID registration. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
  7. Input the transmitter IDs using the Techstream and transmit them to the tire pressure warning ECU.
  8. The "ID Registration is complete" is displayed on the Techstream display.
    NOTE:
    • The previously registered IDs will be deleted from the memory when the registration is completed.
    • Registration can be performed during initialization. However, the initialization will be cancelled when the registration is started.
  9. Confirm tire pressure data from all wheels is displayed on the Techstream display.
    NOTE:
    • It may take about 2 or 3 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 IDs have not been registered, DTC C2171/71 will be 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.
    • After all IDs are registered, DTC C2126/26 (Transmitter ID not Received in Main Mode) 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 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.
