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.
|
|
| 2. |
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).

Description
The GDI injector is similar to a standard injector, but sprays fuel at a much
higher pressure directly into the combustion chamber and has a swirl disc to
get the fuel swirling as it exits the nozzle. This aids in atomization of the
fuel.
The ECM controls bo ...
The lane is not visible due to snow, rain, debris, puddles or other environmental
conditions.
The brightness outside changes suddenly such as when entering/exiting
a tunnel.
The headlights are off at night or the vehicle is in a tunnel.
