INSPECTION PROCEDURE

Note:
  • When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

  • It is necessary to perform initialization (Click here) after registration (Click here) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.

    CHECK HARNESS AND CONNECTOR (TIRE PRESSURE WARNING ECU AND RECEIVER - TIRE PRESSURE WARNING ANTENNA)


    1. Disconnect the tire pressure warning ECU and receiver L175 connector.

    2. Disconnect the tire pressure warning antenna (for Roof Side) S107 connector.

    3. Disconnect the tire pressure warning antenna (for Front Side) A99 connector.

    4. Measure the resistance according to the value(s) in the table below.

      Tip:

      Because the coaxial cable that is used for the tire pressure warning antenna consists of a center conductor and an outer shielding layer (-), this measurement should be performed to ensure that there is no malfunction in the coaxial cable.

      Standard Resistance
      Tester Connection Condition Specified Condition
      L175-9 (ANT4) - S107-1 (ANR) Always Below 1 Ω
      L175-8 (ANT2) - A99-1 (ANFL) Always Below 1 Ω
      L175-9 (shielded wire) - S107-1 (shielded wire) Always Below 1 Ω
      L175-8 (shielded wire) - A99-1 (shielded wire) Always Below 1 Ω
      L175-9 (ANT4) - S107-1 (shielded wire) Always 10 kΩ or higher
      L175-8 (ANT2) - A99-1 (shielded wire) Always 10 kΩ or higher
      L175-9 (shielded wire) - S107-1 (ANR) Always 10 kΩ or higher
      L175-8 (shielded wire) - A99-1 (ANFL) Always 10 kΩ or higher
