Kia Sportage: Tire Pressure Monitoring System / TPMS Receiver Description and operation
| 1. |
Mode
| (1) |
Virgin State
| •
|
The receiver as a sole part is shipped in this state.
Replacement parts should therefore arrive in this state.
|
| •
|
In this state, there is no Auto-Location, no sensor
wake-up, no sensor monitoring and no DTC monitoring.
|
| •
|
The state indicates that platform specific parameters
must be written to the receiver and that sensors are
un-learned.
|
|
| (2) |
Normal State
| •
|
In order for tire inflation state and DTC monitoring
to occur, the receiver must be in this state.
|
| •
|
In this state, automatic sensor location / learning
is enabled.
|
|
|
| 2. |
Overview
| • |
Learn TPMS sensor for under inflation monitoring automatically.
|
| • |
Uses sensor information, distance travelled, background noise
levels, Auto-learn status, short / open circuit output status,
vehicle battery level, internal receiver states to determine
if there is a system or a vehicle fault.

General Function
| • |
Auto-learn takes place only once per Ignition cycle.
|
| • |
On successful completion, 4 road wheel sensor ID's are latched
into memory for monitoring.
|
| • |
Until Auto-learn completes, previously learned sensors are monitored
for under inflation / leak warnings.
|
|

General Conditions to Learn New Sensors:
| • |
Receiver must determine that it is confident that sensor is
not temporary:
|
| b. |
Uses confidence reduction of previously learned sensors.
|
| • |
Typical time at driving continuously over 15.5 mph(25 kph) to
learn a new sensor is up to 20 minutes.
|
|
| 3. |
General Conditions to Un-Learn a sensor that is removed :
| • |
It takes less than 20 minutes at 15.5 mph(20~30 kph).
|
| • |
Confidence reduction is dependent on time which vehicle is driven
at speed greater than or equal to 12.4 mph(20~30 kph).
