Initializing Tire Pressure Monitor System

NOTE: The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced; or when a new vehicle is delivered. Set tire pressure within the specified range before initializing.

NOTE: When initializing the system, the present tire condition is stored as a standard.

During initialization, the tire pressure monitor valve sub-assembly measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure monitor ECU at a frequency of one per 3 minutes. The initialization process is completed when the signals from the 5 tires have been received.

Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
With the vehicle stopped and parking brake applied, turn the ignition switch to the ON position.
Press and hold the tire pressure warning reset switch until the tire pressure warning lamp blinks 3 times at one-second intervals.
Confirm that initialization is complete using the hand-held tester. First select "DATA LIST" on the hand-held tester, then verify that the "TIREPRESS" values are displayed. It may take 5 to 6 minutes for the "TIREPRESS" values to display on the hand-held tester screen
NOTE: The initialization process takes 5 to 6 minutes to be completed. The initialization process can be terminated by connecting terminals 4 (TC) and 13 (CG) of the DLC3.
