Initialization

TIRE PRESSURE MONITORING: 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 a tire pressure warning valve and transmitter.*

* Specified tire pressure changes depending on the size or type of tire.

* When changing the tire inflation pressure by changing traveling speed or load weight, etc.

HINT
*: Perform initialization after the transmitter ID registration is completed Registration.

(b) Before initialization

(1) Set the tire pressures of all tires to the specified values Pressure, Vacuum and Temperature Specifications.

NOTICE:
Make sure the tires are cooled down.

2. INITIALIZATION PROCEDURE

(a) Turn the power switch on (IG).

(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 power switch off.

(d) Connect the Techstream to the DLC3.

(e) Turn the power switch on (IG) and the Techstream 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 is displayed on the Techstream 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.
* While in test mode, the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
* The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.






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 C2125/25 C2121.
