TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION

TIRE PRESSURE WARNING SYSTEM: 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:





NOTICE: 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) Turn the ignition switch on.





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

(c) Turn the ignition switch off.
(d) Connect Techstream to the DLC3.
(e) Turn the ignition switch on and turn the tester on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(g) Check that the initialization has been completed.
(h) Confirm that the tire pressure data of all tires are displayed on the tester screen.
NOTICE:
- The initialization is normally completed within 2 to 3 minutes.
- If the initialization has not been completed successfully, DTC C2177/77 is set after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
- The initialization can be terminated by connecting terminals TC and CG of the DLC3 connector.




(1) Techstream

Tire Pressure Monitor





HINT:
- The initialization is complete when the DATA LIST "ID Tire Inflation Pressure" display shows the correct pressures.
- *: 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.
