Toyota Corolla Cross: Initialization

INITIALIZATION

NOTICE:

  • Initialization can be confirmed through the tire pressure warning light.
  • If the ignition switch is turned off during initialization, the tire pressure warning ECU and receiver memorizes that initialization was being performed. Therefore, it is not necessary to perform the initialization procedure again after turning the ignition switch to ON. (Only when "Setting by Current Pressure" is selected.)
  • The order in which the data is received is random. (Only when "Setting by Current Pressure" is selected.)
  • If the signals from all the tire pressure warning valve and transmitters are received, initialization is completed. (Only when "Setting by Current Pressure" is selected.)
  • When "Complete" is displayed for the value of Data List item "Initialization Not Completed", the initialization is completed.

  • Initialization is normally completed within a few minutes. (Only when "Setting by Current Pressure" is selected.)
  • If initialization has not been completed successfully, Vehicle Control History (RoB) X20FE is stored after a vehicle speed of 40 km/h (25 mph) or more continues for 20 minutes or more. (Only when "Setting by Current Pressure" is selected.)
  • Even if initialization is performed, the existing tire positions will not be cleared. Perform the tire position identification procedure as necessary.

BEFORE INITIALIZATION

(a) Set the tire pressure to the specified value.

NOTICE:

Refer to the link as the procedure for adjusting the tire pressures differs depending on the temperature of the tires.

HINT:

The tire pressure warning system illuminates the tire pressure warning light to warn the driver when any of the following condition is met:

  • The tire pressure drops to approximately 75% or less of the tire pressure set when system initialization was performed using the steering pad switch assembly.
  • The tire pressure drastically decreases (approximately 25 kPa (0.25 kgf/cm2, 3.6 psi) or more within several minutes) to approximately 75% or less of the tire pressure* when the tires are warmed.

    *: If initialization is performed and the vehicle is driven for a certain period of time, the tire pressure set during system initialization is adjusted and set to the tire pressure when the tires are warmed from the driving conditions.

    NOTICE:

    If the tire pressure is decreased approximately 25 kPa (0.25 kgf/cm2, 3.6 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 75% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 75% of the tire pressure set when the tires are warmed. In this case, perform initialization again.

INITIALIZATION PROCEDURE

(a) Using the steering pad switch assembly, select "Tire Pressure Setting" and then "Setting by Current Pressure" on the multi-information display and check that the tire pressure warning light blinks 3 times.
