2013 SSANGYONG KORANDO ignition

Ignition status change*
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) ESCL JAM warning
The SKM transmits the warning active command to the BCAN through the BCAN signals such as ESCL
NOT LOCKED warning signal or ESCL JAM warning signal within 10 seconds or until the active
command deactivation conditions will be met, if jam is occurred when the electric steering motor is
locked/unlocked.
Failure Detecting Conditions
When the UNLOCK retry occurs after ESCL LOCK command, the ESCL LOCK is performed.
- The UNLOCK retry is possible up to 2 times automatically. If the UNLOCK retry occurs 3 times
in succession, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the ESCL LOCK conditions are met.
When the LOCK retry occurs after ESCL LOCK command, the command will be overridden without
retry.
- After the command is overridden, the ESCL NOT LOCKED warning is triggered.
- Reactivates when the LOCK conditions are met by pressing the START/STOP switch after
ESCL UNLOCK.
When the LOCK retry occurs after ESCL UNLOCK command, the ESCL UNLOCK is performed.
- The LOCK retry is possible up to 2 times automatically. If the LOCK retry occurs 3 times in
succession, the ESCL JAM warning is triggered.
- Reactivates when the ESCL UNLOCK conditions are met by pressing the START/STOP
switch.
When the UNLOCK retry occurs after ESCL UNLOCK command, the command will be overridden
without retry.
- After the command is overridden, the ESCL JAM warning is triggered.
- Reactivates when the UNLOCK conditions are met by pressing the START/STOP switch after
ESCL LOCK. 1.

(10) Brake not working alert
The SKM sends the brake not working alert signal for 10 sec. every time the ignition status is changed
after the 1st cycle (OFF-ACC-IGN-ACC-OFF)
while the brake is not operated.
when the brake pedal is depressed, the system is reset and alert deactivation signal is sent.
when the 10 min. timer is terminated -
-
(11) Smart key slot detection alert
The SKM sends the smart key slot detection alert signal for 10 sec. when a smart key inserted into
the slot is detected with IGN OFF and the driver's door open. -

3) Operating Process
Key verification can be divided into two types, immobilizer key verification and smart key verification. The
immobilizer verification is applied for the SKM system, and verifies the transponder built in the smart key.
When the smart key is inserted into the slot, the verification is carried out, overriding the RF signal from
the smart key.
The power is supplied to the slot when the START/STOP switch is pressed with the smart key inserted
into the slot, and the smart key transponder verification is carried out by the transponder communication.
Once the key is verified, a valid key verification time is provided for 10 seconds and the engine can be
started by pressing the START/STOP switch during this time. If pressing the START/STOP switch after
this 10 seconds, the key verification process is performed again.
When the ignition is turned ON, the EMS (ECU) sends the challenge message to the SKM through
the P-CAN. (This is to verify whether the transponder of the smart key is valid. If the verification fails,
it transmits the re-verification signals 3 times for 2 seconds. If 3rd re-verification fails, the verification
is deactivated for 10 seconds and re-activated after that.)
The immobilizer slot of the SKM system sends the encrypted cod to the transponder, and the
transponder re-sends the encrypted code to the immobilizer slot.
The encrypted sent to the immobilizer slot is re-sent to the SKM.
The SKM compares this code with the encrypted code randomly transmitted by the internal logic.
(System compares the signal from transponder and encrypted signal from the immobilizer control
unit)
Only when the two signals are identical, it recognizes the key as the verified one and transmits the
positive message to the ECU.
The ECU enables the engine to be started. 1.
