3) REKES Control Function
(2) REKES UNLOCK
The SKM receives the signal for [REKES UNLOCK] 0.1 sec. after the UNLOCK button on the smart
key is turned ON, and sends this signal through the BCAN. - When the SKM receives the REKES signals by the buttons on the smart key, it transmits the
corresponding signals through the BCAN.
Switch Stage Remark

(3) Remote keyless tailgate open
When the SKM receives the signal for [REKES UNLOCK] by the UNLOCK button on the smart key, it
transmits this signal through the BCAN.
(1) REKES LOCK
The SKM receives the signal for [REKES LOCK] 0.1 sec. after the LOCK button on the smart key is
turned ON, and it transmits this signal through the BCAN.
When the REKES LOCK signal is received with the ACC ON, the ACC is turned OFF and the signal
for [REKES LOCK] is sent. -
- When the SKM receives the signal for [REKES LOCK] by the LOCK button on the smart key, it transmits
this signal through the BCAN.
The SKM receives the tailgate open signal 1 sec. after the tailgate open button on the smart key is
turned ON with the ignition status OFF, ACC or IGN ON, and it transmits the signal for [REKES
tailgate open] through the BCAN. - When the SKM receives the signal for [REKES tailgate open] by the tailgate open button on the smart
key, it transmits this signal through the BCAN.

4) Smart Key Verification Time Control
(1) Pre-verification timer
When the operation signal from the START switch is received, the START & power control functions can
be performed without smart key verification.
(2) Immobilizer verification timer
The immobilizer verification status indicates that it is possible to respond to the request message sent
from the EMS to deactivate the immobilizer. The SKM verified a smart key and the engine can be
started.
The 30-second immobilizer verification time is started when:
the ignition status is changed to IGN by the START switch while the pre-verification timer is activated.
the ignition status is changed to IGN by the smart key verification while the pre-verification timer is
stopped; the SKM verified a smart key by the brake switch signal while the immobilizer verification
timer is stopped or the ignition status is IGN ON.
the SKM verified a smart key successfully if the immobilizer verification timer is stopped with IGN
ON/immobilizer verification /brake switch ON. -

Condition SKM operation
- when door closed signal is input with - B+ or ACC ON
- when brake is applied with - B+ or ACC ON
- when START switch is operated with - B+
- when smart key is inserted into slot & brake switch is
operated or START switch is operated with - B+Once the vehicle interior verification
is completed, 30 sec. pre-verification
timer is started
when the ignition is turned OFF with IGN ON and engine
running 30 sec. pre-verification timer is
started without re-verification
Timer deactivation conditions: after 30 sec. has passed, IGN ON, Outside door handle switch ON,
entering theft deterrent mode when door condition is changed
IGN1 OFF
30 sec. has passed after immobilizer verification
Any door is opened and then closed when all doors are closed & smart key out
When the engine starts to run, the immobilizer verification status is determined, and the immobilizer will
not be deactivated until the ignition status is changed to IGN/ACC/OFF.
The immobilizer is not deactivated when the key out warning condition is met while the engine is
running. (when the RND is received by the EMS reset while the engine is running)
When attempting to start the engine without immobilizer verification, the system performs smart key
verification procedures, and sends the engine start request to EMS only when the verification result is
normal. -

(2) Ignition status change
The ignition status is changed to OFF, ACC ON, IGN ON and engine cranking by one START/STOP
button.
The SKM cuts the power for IGN2 and ACC relays while the engine is cranking as cutting the electric
load is necessary.
The SKM monitors the brake pedal status through the hardware signals.
The ignition status change is available when the engine START/STOP button is pressed.
The SKM uses the EMS (engine condition) and ABS/ESP (FR vehicle speed) signals sent through the
P-CAN bus (High Speed CAN).
When the smart key battery is discharged and the driver inserts the smart key into the immobilizer slot
in emergency mode, the smart key verification is performed if the brake or START switch is pressed
before the ignition status is changed (ACC ON, IGN ON).

When the engine START/STOP switch is pressed for 3 sec. or more at more than 3 km/h, the
ignition status is changed from IGN to ACC.
If the engine START/STOP switch is pressed again, the ignition status is changed from ACC to
IGN.
The 4 vehicle speeds are abnormal (CAN signal timeout, abnormal signal):
If the engine START/STOP switch is pressed for 3 sec., the ignition status is changed from IGN
to ACC. If the switch is pressed again, the ignition status is changed from ACC to OFF (DTC
set). -
-
The SKM changes the ignition status as follows: 8.

Ignition status change
(OFF ->ACC) / (OFF ->IGN)/(ACC ->IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies the transponder and sends the verification
status for another 10 sec.
When the ignition status is changed by a smart key verification while the transponder verification is
processed, the SKM sends the signal for [transponder verification fail], and sends the smart key
verification status for 10 sec. -
-
(6) Transmission position warning
When the gear selector lever is in a position other than P or N with IGN ON and engine started, the
SKM sends the [gear position warning] signal to the instrument cluster through the BCAN for up to 10
sec. until the operating conditions are deactivated.
Transmission position warning deactivation ▶
When re-attempting to start with IGN1 ON and transmission in P or N -
(7) SKM error alert
The SKM sends the SKM error alert signal to the instrument cluster through the BCAN for up to 10 sec.
when an in ignition status related error or passive entry system error occurs.
SKM error transmission conditions ▶
When any of the following errors is detected and a DTC is set, the SKM sends the error alert signal for
10 sec.
B+ (power) low voltage
B+ (logic) low voltage
ACC ON fail
ACC OFF fail
IGN1 ON fail
IGN1 OFF fail

The SKM sends the corresponding signal only once for 10 sec. when any of the above errors is detected
with IGN OFF/ON. It sends the signal again when a new error occurs.

Engine oil level warning lamp ▶This lamp comes on if any sensor or device related to the engine control is
defective.
This lamp comes on when the start switch is ON or when the battery level is
low.
(For EEM, warning lamp is controlled according to CAN signal)
This lamp comes on when the ignition switch is turned to "ON" position,
and then goes off if the engine oil level is normal.
If the engine oil level warning lamp comes on while driving, check the
engine oil level and oil leakage. -
- This indicator comes on when the ESP system is faulty.
This indicator comes on when pressing the ESP OFF switch.

ON position.
IGN ON detecting time: 40~80 ms after turning ignition switch to ON position -
- The pre-warning is performed for 4 seconds after turning the ignition switch to ON position. BCM checks
that the warning lamps (ABS, ESP, ESP OFF, 4WD CHECK, 4WD LOCK) are matched with CAN
signals.
The pre-warning is performed by the variant code.
