Kia Optima: Tire Pressure Monitoring System / TPMS Receiver
Description and operation
TPMS Receiver : IBU (Integrated Body Control Unit) integrated management

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.
|
|
1. |
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 :
a. Uses vehicle speed.
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).
|
|
Repair procedures
1. |
Remove the Integrated Body Control Unit (IBU).
(Refer to Body Electrical System - "Integrated Body Control Unit (IBU)")
|
1. |
Install in the reverse order of removal.

Vehicle Name Writing
The main contents of diagnostic method using diagnostic device are as follows:
1. |
Connect self-diagnosis connector (16 pins) located in the lower driver
side crash pad to self-diagnostic device, and then turn on the self-diagnostic
device after key is ON.
|
2. |
Select the "IBU-TPMS" and "Vehicle Name Writing" on KDS vehicle selection
screen, then select OK.


The vehicle naming (Read/Write) is automatically typed and just select
the vehicle's option in the selection tab below.
※ The vehicle naming code is different as the vehicle models

side crash pad to self-diagnostic device, and then turn on the self-diagnostic
device after key is ON.
|
2. |
