Initializing Tire Pressure Monitor System: Notes

CAUTION: Set tire pressure within the specified range before initializing. DO NOT start initializing without adjusting tire inflation pressure of all tires (including the spare tire). Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal.

NOTE: The system will need to be initialized when tires are rotated, replaced with tires of different pressures, or tire pressure sensor and/or tire pressure monitor ECU are replaced. Set tire pressure within the specified range before initializing. When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized (registered) by the tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE SENSOR REGISTRATION .

During initialization, the tire pressure sensor 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 minute.

NOTE: If the engine switch is turned off during initialization, it is not necessary to restart the initialization procedure from the beginning as it will begin automatically when the engine switch is turned back to IGNITION ON mode.
