Kia Forte: Operation
Passive Functions
The system allows the user to access the vehicle without having to perform
any actions (e.g. RKE button pressing) with the SMART KEY FOB. It is sufficient
that a valid SMART KEY FOB is located within a defined and limited range with
respect to the vehicle. So the system is capable of detecting and authenticating
a SMART KEY FOB in the ranges as specified below.
| Operating Range |
The SMART KEY FOB receives and interprets a challenge sent from the vehicle
via the exterior antennas in a free space range of min. 0.7m measured around
the exterior antennas which are integrated in the door handles. The trunk access
range is also min. 0.7m measured from the antenna position.
Passive Access (Passive Entry)
Pressing one of the push buttons in the door handles when all doors locked
indicates the operator’s intent to access the vehicle and thus triggers the
system for unlock
Passive Locking (Exit)
Pressing one of the push buttons in the door handles when one of the following
condition is fulfilled:
| • |
All door is closed and at least one door is unlocked.
|
indicates the operator’s intent to lock the vehicle and thus triggers
the system for a lock.
Passive Open Trunk
Pressing the Trunk Lid Switch when trunk is closed indicates the operator’s
intent to open the trunk and thus triggers the system. Subsequently, the SMK
ECU sends a LF-challenge to the SMART KEY FOB via the exterior bumper antenna.
The SMART KEY FOB answers with a RF-response. If the received response matches
the expected answer, SMK ECU sends a “trunk open” message via the CAN network.
Passive Trunk Warning
Whenever the trunk is closed, SMK ECU uses a suitable search strategy
to avoid trunk buzzer warning by a fob inside the vehicle. Then SMK searches
for a SMART KEY FOB in the interior of the trunk. If a valid SMART KEY FOB is
found in the trunk, the SMK ECU activates SMK external buzzer (TBD) to inform
the user that the trunk has been closed with a fob inside the trunk.
SMK will send the trunk open command to BCM for trunk reopening if trunk
reopening bit is set(BK)For this functionality, a “valid” SMART KEY FOB means
any SMART KEY FOB that belongs to the vehicle, even if it’s DEACTIVATED.

Smart Key Reminder 1
| 1. |
Preconditions:
All terminals OFF & at least one door open & locking status is
not locked checked by SMK periodically every 100ms, as long as CAN/LIN
active.
|
| 2. |
Event:
At least 1 door knob status changed from unlock to lock.
|
| 3. |
SMK actions:
If no fob or no TP has been found, no action is required.
If any valid fob or valid TP has been found, SMK unlocks the vehicle
by sending a CAN Key Reminder unlock message with the fob number.
If any valid fob has been found, SMK unlocks the vehicle by sending
a CAN/LIN Key Reminder unlock message with the fob number.
|
Smart Key Reminder 2
| 1. |
Preconditions:
All terminals OFF & any door (including trunk) open & no FOB-IN
& no locking status (checked by SMK periodically every 100ms, as long
as CAN/LIN active)
|
| 2. |
Vehicle action:
Closing last door or trunk with knobs locked state, or with a
locking in progress
|
| 3. |
SMK actions:
Before elapsing 500ms after the closing if all doors are locked
then:
If no fob has been found, no action is required.
If any valid fob or valid TP has been found, SMK sends unlock
command via CAN and activates ext. buzzer warning.
If any valid fob has been found, SMK sends unlock command via
CAN/LIN and activates ext. buzzer warning.

Smart Key Door Lock Warning
Door Lock Warning 1
| 1. |
Preconditions:
While (at least one door knob is unlocked) & (ACC ON or IGN ON)
& (No FOB-IN) :
|
| 2. |
Event:
|
| 3. |
SMK actions:
SMK performs a search for the fobs outside of the vehicle; the
same LF-strategy has to be used as it is defined for "Scenario Access
with I/O Distinction".
|
Door Lock Warning 2
| 1. |
Preconditions:
Same as passive locking precondition but with at least one door
open.
|
| 2. |
Event:
User presses the door handle Push button .
|
| 3. |
SMK actions:
SMK performs a search for the fobs outside of the vehicle; the
same LF-strategy has to be used as it is defined for "Scenario Access
with I/O Distinction".
If no fob has been found, no action is required.
If the preconditions are no longer valid during buzzer active
time (3 seconds), the SMK ECU stops the buzzer immediately.
|
Door Lock Warning 3
| 1. |
Preconditions:
Same as passive locking precondition
|
| 2. |
User action:
|
| 3. |
SMK ECU actions:
|
If no fob has been found, the passive locking is performed.
If any valid fob has been found, SMK ECU activates the external buzzer.
If the activity timer elapsed or ACC ON or IGN1 ON or NOT All door closed
or FOB-IN, the SMK ECU stops the buzzer immediately.
After searching of inside fob, SMK ECU also performs a search for fobs
outside of the vehicle.
Smart Key Lamp Warning
| 1. |
SMK actions:
As long as the preconditions are valid, the SMK ECU performs a
periodical search for the fobs in the interior of the vehicle; the same
LF-strategy has to be used as it is defined for the ID out warning (registering
only, no authentication); periodical means, the search is done every
3 seconds.
If no fob has been found, the SMK ECU starts Key out indicator
lamp activation as all preconditions are valid and will perform another
search 3 seconds later.
|
If any valid fob has been found, the SMK ECU stops the Key out indicator
lamp and will (if one door is open) perform another search 3 seconds later;
if no door is open then it’s only at the next When the preconditions are still
valid, the search resumes by opening of one door.
Failsafe Functions (Backup For Limp Home)
In case of a discharged battery of the SMART KEY FOB or disturbed transmission,
the following functions are available:
| • |
Unlocking / locking of doors or trunk (or tailgate depending of
the vehicle configuration): use of mechanical key
|
User Information Functions
| ID OUT Warning |
| 1. |
Preconditions:
|
| 2. |
Event:
The last opened door is closed
|
| 3. |
SMK action:
SMK searches for a SMART KEY FOB in the interior.
|
If there is a LF error (LF overheating or LF antenna failure),
the system will have the same behavior as it is with no fob found.
|
Immobilizer Lamp
Removing the PIF from the MSL and reinserting the PIF and pushing the
MSL Knob will switch the lamp on again.
Fob Battery Low Voltage Detection
To detect fob low battery condition, certain battery voltage measurement
and low voltage detection strategy are implemented into fob. The measurement
of the battery voltage will be done if fob button is pressed or if a LF measurement
command is received.
If the fob has detected a low battery voltage, the LED will not be switched
on at button press.
Learning Description
In this chapter, the learning procedure for SMK, FOBs is described.
For the learning of the SMK, FOBs, it's necessary to have a connection
to the diagnostic tool.
Learning MODE
Whatever the mode, the learning procedures are managed by the SMK.
Prior to start learning service, Fob-In signal must be active and the
vehicle secret code (called as PIN code) should be known.
Teaching MODE
This mode is used by the dealers in order to replace SMK and/or the set
of keys, or to register additional keys for an existing system. That means the
system already has been learnt with certain PIN Code. The PIN Code is fixed
for the life time of the vehicle, therefore the same PIN Code must be used in
this mode. Otherwise learning will be failed
Teaching MODE Procedure Description (Step By Step)
Objective: Key teaching procedure at service station
Initial state:
| - |
SMK replacement: SMK is not learnt, SMART FOB are already learnt
with same PIN code
|
| - |
Additional or new keys teaching: SMK is already learnt with same
PIN code
|
