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