Initialization

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION

INITIALIZATION

1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
- Before delivery of a new vehicle.
- After replacement of the tire pressure warning ECU*.
- After replacement of the tire pressure warning valve and transmitter.
- Specified tire pressure changes depending on the size or type of the tire.
- After the tire rotation.
*: Perform initialization after the transmitter ID registration is completed Registration.
(b) Before initialization
(1) Set the air pressure of all wheels to the specified value.
Cold tire inflation pressure:





NOTE: Perform the tire pressure adjustment after the vehicle has sufficiently cooled down. If the vehicle is not sufficiently cooled down, increase the air pressure by 20 to 30 kPa (0.2 to 0.3 kgf/cm2, 2.9 to 4.3 psi) above the specified value.

2. INITIALIZATION PROCEDURE
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Select "TIRE PRESS" by following the prompts displayed on the intelligent tester.






(e) Press the tire pressure warning reset switch within 30 seconds after turning the ignition switch to the ON position. Keep the tire pressure warning reset switch pressed for 3 seconds or more with the ignition switch in the ON position.

(f) Check that the tire pressure warning light blinks 3 times (1 second ON, 1 second OFF).
HINT: Initialization will be completed if signals are received from all wheels.

(g) Turn the ignition switch off.
(h) Turn the ignition switch to the ON position.






(i) Wait for 2 or 3 minutes with the ignition switch in the ON position.
- The initialization is normally completed within 2 to 3 minutes.
- If the initialization has not been completed successfully, DTC C2177/77 is set after approximately 20 minutes.
- The initialization can be terminated by making a short circuit between terminals TC and CG of the DLC3 connector.

3. CHECK THAT INITIALIZATION HAS BEEN COMPLETED
(a) Confirm that the data of tire pressure of all tires are displayed on the intelligent tester screen.

TIRE PRESSURE:





HINT:
- *: It may take about 2 or 3 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.
- The initialization is complete when the DATA LIST "TIRE PRESS" or "ID Tire Inflation Pressure" display shows the correct pressures.
