TIRE AND WHEEL: 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 Service Precautions.
NOTICE:
Make sure the tires are cooled down.
2. INITIALIZATION PROCEDURE
(a) Turn the engine 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 engine switch off.
(d) Connect the Techstream to the DLC3.
(e) Turn the engine 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.
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.
3. INITIALIZATION PROCEDURE (MULTI-INFORMATION DISPLAY)
(a) Turn the engine 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.
HINT
* The initialization can be confirmed through the multi-information display.
* The order in which the data is received is random.
* If the signals from all the wheels are received, the initialization is complete.
* 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.
