General Function

A.	Auto-locate/learn takes place only once per Ignition cycle.

B.	On successful completion, 4 road wheel sensor ID's, together with their respective road wheel positions are latched into memory for monitoring.

C.	Until Auto-learn completes, previously learned sensors (together with their respective locations) are monitored for under inflation / leak warnings.

D.	Spare tire inflation / DTC state is not displayed.

General Conditions to Learn New Sensors:

A.	Receiver must Auto-Locate 4 road sensors.

2)	Uses confidence reduction of previously learned sensors.

D.	Typical time at driving over 20 kph to learn a new sensor is up to 10 minutes.

General Conditions to Un-Learn a sensor that is removed:

A.	It takes less than 10 minutes at 20~30kph.
