  1. INITIALIZATION PROCEDURE

Tire Pressure Warning System -- Initialization


NOTICE:
  1. Initialization can be confirmed through the tire pressure warning light.
  2. The order in which the data is received is random.
  3. If the signals from all the wheels are received, initialization is completed.
  4. Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures (LandCruiser RM000000XMY0BZX.html).
  5. Initialization is normally completed within a few minutes.
  6. It may take up to 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).
  7. If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 37 km/h (23 mph) or more continues for 20 minutes or more.
  8. During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
  9. w/ ID Switching Function:
    While the answer-back function for the ID switching function is operating, the system will not change to initialization mode even if the tire pressure warning reset switch is pressed.
