Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Suspension System / Tire Pressure Monitoring System / TPMS Receiver Description and Operation

Operation

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.

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.

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.
