CAUTION / NOTICE / HINT

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 initializationafter registration Click here of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU and/or one of the valve and transmitters has been replaced.

PROCEDURE


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


    1. Disconnect the R65 tire pressure warning ECU and receiver connector.

    2. Disconnect the A94 front tire pressure antenna connector.

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

      Tech Tips

      Because the coaxial cable that is used for the front tire pressure 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
      R65-1 (ANT1) - A94-1 (ANFL) Always Below 1 Ω
      R65-1 (shielded wire) - A94-1 (shielded wire) Always Below 1 Ω
      R65-1 (ANT1) - A94-1 (shielded wire) Always 10 kΩ or higher
      R65-1 (shielded wire) - A94-1 (ANFL) Always 10 kΩ or higher

  2. CHECK FRONT TIRE PRESSURE ANTENNA RECEPTION


    1. Set the tire pressure to the specified value.

      Click here

    2. Turn the engine switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

    6. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

    7. Check the values by referring to the table below.

      Tech Tips


      • *1: It may take a few minutes until the values are displayed.

      • When an "ID Tire Inflation Pressure" value has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the value.

      ID 1 Tire Inflation Pressure
      ID 2 Tire Inflation Pressure
      ID 3 Tire Inflation Pressure
      ID 4 Tire Inflation Pressure

    8. Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.


      1. Check that each "ID Tire Inflation Pressure" value displayed on the GTS has changed.
