  3. Connect the Techstream to the DLC3.
  4. Turn the ignition switch ON and the Techstream on.
  5. Select the registration mode "MAIN".
    6. NOTE:
    • Check that the tire pressure warning select switch is set to "Main".
    • When registering a second set, select the registration mode "2nd" after changing the tire pressure warning select switch to "2nd".
    • 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 canceled when the registration is started.
    • If this step is not completed within 300 seconds, this mode will be canceled.
  6. Enter the menu items in this order: Chassis / Tire Pressure Monitor / Utility / ID Registration.
  7. Perform the procedures displayed on the screen.
  8. Confirmation of transmitter ID registration:
    1. Enter the menu items in this order: Chassis / Tire Pressure Monitor / Data List.
    2. Read the "ID Tire Inflation Pressure" values.
    3. Confirm that the tire pressure data of all tires is displayed on the screen.
NOTE:
  • It may take up to about 2 or 3 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 C2125/25 *1 or C2131/31 to C2135/35 *2.
  • If the IDs have not been registered, DTC C2171/71 *1 (Transmitter ID not Registered in Main Mode) or C2172/72 *2 (Transmitter ID not Registered in 2nd Mode) 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 *1 (Transmitter ID not Received in Main Mode) or C2127/27 *2 (Transmitter ID not Received in 2nd Mode) 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 information from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 *1 or C2127/27 *2 is deleted and the tire pressure warning light goes off.
