* After replacement of the tire pressure warning valve and transmitter*.

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

HINT
*: Perform initialization after the transmitter ID registration is completed Registration (from 12/2010).

(b) Before initialization

(1) Set the air pressure of all wheels to the specified value Precaution (from 12/2010).

NOTICE:

3. CHECK THAT INITIALIZATION HAS BEEN COMPLETED

(a) Confirm that the data of the tire pressure of all wheels are displayed on the Techstream display to confirm that the initialization has been completed.

(1) Turn the ignition switch off.

(2) Connect the Techstream to the DLC3.

(3) Turn the ignition switch on (IG).

(4) Turn the Techstream on.

(5) Check the Data List. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tire Pressure Monitor:





HINT
* The initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.
* *1: 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 Tire Pressure Monitoring (from 12/2010).
