HINT:

*: It may take about 5 to 6 minutes until the values are displayed. If the values are not displayed after several minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (See page TW-42).

NOTICE: The following operations can be used instead of above procedure:

1. Turn the ignition switch from OFF to ON.

2. Monitor the tire pressure values of all the wheels using the intelligent tester.

3. If the tire pressure values cannot be displayed on the intelligent tester screen, the initialization has failed.

4. It takes about 5 to 6 minutes to display the tire pressure data.
