Tire Pressure Warning System -- Registration



1. DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.
Prepare all transmitter ID data before starting registration.

  1. Before registration

    1. When replacing the tire pressure warning ECU:

      1. Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
      2. 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 (COROLLA_ZRE142 RM000000X98035X.html).

    2. When replacing a tire pressure warning valve and transmitter:


      1. Take note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

        NOTICE:
        1. 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 on the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.
        2. The ID registration must be performed for all tire pressure warning valve and transmitters. Check the Data List, replace the exchanged ID with a new ID, and make a new DATA LIST of all 4 tires for the vehicle.


2. REGISTER TRANSMITTER ID (Using Techstream)

  1. Set the all tire pressure to the specified value (COROLLA_ZRE142 RM000000X98035X.html).

  1. Turn the ignition switch off.

  1. Connect the Techstream to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the Techstream on.

  1. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

  1. Perform the following procedures displayed on the screen.

  1. 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 data of tire pressure of all tires are displayed on the Techstream.

      NOTICE:
      1. 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 (COROLLA_ZRE142 RM000000ZUQ08HX.html).
      1. If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
      1. If normal pressure values are displayed, the IDs have been registration correctly.
      1. If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
      2. 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 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.
