(4) Engine stop
When the START button is pressed at the vehicle speed of 3 km/h or less, the SKM turns off the IGN
relay to stop the engine.
When the vehicle speed is 3 km/h or more or no speed signal is input, the SKM performs the
following functions: 1.
2.
When the START 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 switch is pressed again, the ignition status is changed from ACC to IGN.
When the START switch is pressed for 3 sec. or more with no vehicle speed signal (CAN signal
timeout, abnormal signal), the ignition status is changed from IGN to ACC. If the switch is pressed
again, the ignition status is changed from ACC to OFF. -
-
When the START button is pressed and held with IGN ON, the ignition status is changed to OFF.
When the START button is pressed briefly, the ignition status is changed to ACC ON. 3.
(5) ACC ON/Power OFF
The SKM changes the ignition status to OFF from ACC ON when:
the engine START/STOP button is pressed with the brake pedal released after the ignition status is
changed from IGN ON to ACC ON.

8) SKM Warning Control
(1) Smart key not found warning (Key out warning)
If no verified smart key is identified as being in the vehicle with IGN ON or ACC ON, the SKM sends the
signal, which identifies that there is no verified key inside the vehicle, to the BCM and instrument cluster
through the BCAN (Smart key not found warning). This warning continues for up to 10 sec. until the
warning condition is deactivated.
The SKM stops the warning immediately after the warning condition is deactivated.

(2) Smart key detection warning
When a valid smart key sends the LOCK signal from outside of the vehicle or the outside door handle
switch is pressed with no smart key outside, the smart key detection warning signal is output, provided
that all the doors or the tailgate is closed with IGN OFF or ACC ON and a smart key is in the vehicle.
Smart key detection warning conditions ▶
When a valid smart key sends the LOCK signal from outside of the vehicle, the SKM sends the signals
for [external buzzer] and [smart key detection warning] to the BCM and instrument cluster through the
BCAN to inform the driver of the existence of a verified key inside the vehicle, provided that all the doors
or the tailgate is closed with IGN OFF or ACC ON and a smart key is in the vehicle.
Smart key inside vehicle warning 2.
If a smart key including immobilizer slot is identified as being in the vehicle after the outside door handle
switch is pressed, the SKM sends the signals for [external buzzer] and [smart key detection warning] to
the BCM and instrument cluster through the BCAN to inform the driver of the existence of a verified key
inside the vehicle.
These 2 warnings (external buzzer, smart key detection warning) continue for up to 10 sec. until the
warning conditions are deactivated under the above conditions.
The SKM stops these warnings immediately after the warning conditions are deactivated. -

(4) Smart key battery discharge warning (3) Smart key verification fail warning
When the verification is requested for ignition status change or engine starting and no verified smart key
is in the vehicle, the SKM sends the [smart key verification status] signal, which indicates that the
verification has failed, for up to 10 sec. until the verification fail conditions are deactivated.
Verification fail detection and transmission conditions ▶
When the ignition status is changed after a smart key is verified by the START switch ON input, the
SKM sends the verification status for 10 sec. -Normally, the smart key verification warning is one of the smart key fail conditions. -
Ignition status change
(OFF ->ACC) / (OFF ->IGN)/(ACC ->IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies a smart key and sends the verification status for
another 10 sec.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the BCAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 sec. -
-
If low smart key battery is detected during the verification process for ignition status change or engine
start, the SKM sends the signal for [smart key battery low voltage warning] to the BCM and instrument
cluster through the BCAN for up to 10 sec. until the warning condition is deactivated.
Smart key battery discharge confirmation and deactivation ▶
If the smart key battery low voltage is confirmed, the SKM sends the smart key battery low voltage
warning signal.
If the smart key battery is in normal condition, the SKM sends the smart key battery low voltage
warning deactivation signal.
The smart key is the last used key. -
-
*
(5) Transponder verification fail warning
If a verified smart key is not found by the key verification process, the SKM sends the information that
indicates the key is not verified to the instrument cluster through the BCAN for up to 10 sec. until the
verification fail condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart key
inserted into the immobilizer holder. -
Transponder verification fail detection and transmission conditions ▶
When the ignition status is changed after the transponder is verified by the START switch ON input,
the SKM sends the transponder verification status for 10 sec. -

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.
