  1. INITIALIZATION PROCEDURE

Tire Pressure Warning System -- Initialization


NOTICE:
  1. Initialization can be confirmed through the tire pressure warning light.
  2. If the engine 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 engine switch on (IG).
  3. The order in which the data is received is random.
  4. If the signals from all the tire pressure warning valve and transmitters are received, initialization is completed.
  5. Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures (Click here).
  6. Initialization is normally completed within a few minutes. However, it may take 10 minutes or more until the tire pressure of the tire inflation pressure display function is shown.
  7. 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 C2125/25 (Click here).
  8. If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 40 km/h (25 mph) or more continues for 20 minutes or more.
  9. During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
  10. ID Switching Function:
    Initialization can only be performed for vehicles with a tire pressure warning reset switch.
  11. Tire Inflation Pressure Display Function:
    If initialization is performed, the existing tire positions will be cleared, but will be automatically identified when the vehicle is driven at 40 km/h (25 mph) or more for 10 minutes or more.

    Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.

BEFORE INITIALIZATION

  1. Set the tire pressure to the specified value (Click here).

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

INITIALIZATION PROCEDURE
HINT:
for FMVSS138 Type:
The tire pressure warning system illuminates the tire pressure warning light to warn the driver when the following condition is met:
  1. Due to the operation of the tire pressure warning reset switch, the tire pressure drops to approximately 75% or less of the tire pressure set during system initialization.
for ECE-R64 Type:
The tire pressure warning system illuminates the tire pressure warning light to warn the driver when any of the following conditions are met:
  1. Due to the operation of the steering pad switch assembly, the tire pressure drops to approximately 80% or less of the tire pressure set during system initialization.
  2. The tire pressure drastically decreases (approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more within several minutes) to approximately 80% or less of the tire pressure* when the tires are warmed.
  3. *: 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:
for ECE-R64 Type:
If the tire pressure is decreased approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 80% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 80% of the tire pressure set when the tires are warmed. In this case, perform initialization again.

  1. Turn the engine switch on (IG).



  2. Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.

  3. Turn the engine switch off.

  4. Connect the GTS to the DLC3.

  5. Turn the engine switch on (IG) and turn the GTS on.
