Kia Optima Hybrid: Tire Pressure Monitoring System / TPMS Receiver Description and Operation

Operation
1.
General Function
Auto-locate/learn takes place only once per Ignition cycle.
On successful completion, 4 road wheel sensor ID''s, together with their respective road wheel positions are latched into memory for monitoring.
Until Auto-learn completes, previously learned sensors (together with their respective locations) are monitored for under inflation / leak warnings.
Spare tire inflation / DTC state is not displayed.
2.
General Conditions to Learn New Sensors:
Receiver must Auto-Locate 4 road sensors.
Auto-location / learning only functions when speed is more than 20 kph (approx. 15 mph).
Receiver must determine that it is confident that sensor is not temporary:
a.
Uses vehicle speed.
b.
Uses confidence reduction of previously learned sensors.
Typical time at driving over 20 kph to learn a new sensor is up to 10 minutes.
3.
General Conditions to Un-Learn a sensor that is removed:
It takes less than 10 minutes at 20~30kph.
Confidence reduction is dependant on vehicle speed and the number of sensors known to the receiver.
