DESCRIPTION

The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the warning light in the combination meter illuminates. The tire pressure warning ECU and receiver stores a DTC when the tire pressure warning valve and transmitter stops transmitting signals. The signals can be forcibly transmitted by releasing the tire pressure rapidly. The stored DTC is cleared when signal transmission resumes.

DTC No.

INSPECTION PROCEDURE

1.PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF ALL WHEELS

  1. Set the tire pressure to the specified value (LandCruiser RM000003DGS00UX.html).

  1. Turn the ignition switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch ON.

  1. Turn the GTS on.

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

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

    		Actual tire inflation pressure
    		If N/A is displayed, data has not been received.*1
    HINT:
    1. *1: It may take a few 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 (C2121/21 to C2125/25: w/ Spare Tire) (LandCruiser RM000000ZUQ0D5X.html).
    2. *2: w/ Spare Tire
    3. The wheel position cannot be determined from ID1 through ID4 or ID1 through ID5 (w/ Spare Tire) on the Data List.

  1. 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 tire pressure data displayed on the GTS has changed.

      OK:
      Each tire pressure data displayed on the GTS will change to the value of the tire pressure.
      NOTICE:
      1. It may take a few minutes to display the updated tire pressure data.
      2. When the "ID Tire Inflation Pressure" data 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 data.

    2. After confirming that all of the tire pressure data displayed on the GTS has changed, set the tire pressure to the appropriate specified values.

      HINT:
      If the tire pressure data displayed on the GTS has not changed after rechecking, inspect for another problem (LandCruiser RM000000ZUQ0D5X.html).
