battery SSANGYONG KORANDO 2013 Workshop Manual

Room lamp cut off control
The lamp is turned off when entering sleep mode or in alarming status. A. Operation 1.
When the ignition is turned OFF (ignition key removed) with the room lamp switch ON, the room
lamp comes on for 10 minutes and then goes out automatically.
When the room lamp is turned off automatically, the room lamp automatic switching off signal is sent
to the instrument cluster before entering sleep mode. B.
C. Operation 2. (preventing battery discharge)
When the ACC is turned ON or ignition is turned ON with the ignition key inserted, the room lamp is
activated. D. Operation 3.
When the room lamp cut off operation is activated, the BCM sends cut off operation signal to the
instrument cluster through B-CAN to prevent the battery discharge. -

Door LOCK/UNLOCK control by door knob switch
The driver and passenger door LOCK knob switches are in the LOCK position from UNLOCK
position.
The door LOCK relay is activated for 0.5 seconds (T1). A.
B. Operation 1.
The driver and passenger door LOCK knob switches are in the UNLOCK position from LOCK
position.
The door UNLOCK relay is activated for 0.5 seconds (T2). C.
D. Operation 2.
All open doors are closed.
The LOCK signal is input within 0.5 seconds (T3).
The UNLOCK signal for all doors is output once for 0.5 seconds (T4). E.
F.
G. Operation 3.
14. CENTRAL DOOR LOCKING SYSTEM CONTROL
For BCM with SKM, sleep mode is deactivated by receiving the status signals from the driver door
knob switch, passenger door knob switch, rear LH/RH door knob switch, and central door
LOCK/UNLOCK switch through the wiring.
If all doors are unlocked 5 times within 1 minute after door LOCK signal output, because of faulty
door knob switch and door open switch, the doors are forced to lock and not allowed to unlock.
However, the UNLOCK conditions are met, the UNKLOCK signal is input normally. -
-
The door lock/unlock system does not work regardless of the door LOCK/UNLOCK switch position,
when reconnecting the battery. (to reset, turn the ignition ON) -
The signal change from UNLOCK to LOCK is ignored during LOCK/UNLOCK output by the central
door LOCK switch, REKES key, and door handle switch.
If LOCK signal from the switch is input within 0.5 seconds after any door is closed, UNLOCK signal
is output. -
-

AUTO UNLOCK upon receiving air bag deployment signal
Air bag deployment signal is not input for initial 7 seconds (T4) after IGN ON A. Operation 1.
Signal from unlock relay is output for 5 seconds (T3) after 40 ms (T2)
When turning IGN OFF during 5 seconds (T3) of unlock relay signal output
Signal from unlock relay is input for the rest of the time B.
C.
D.
E. Operation 2.
The room lamp comes on when the air bag deployment signal is input except when the room lamp
switch is turned off.
The hazard warning lamp flashes when the air bag deployment signal is input.
Resetting the auto door unlock function turns off the battery (cutting off BCM power). -

-
The door LOCK/UNLOCK relay is installed inside the actuator.

ON.
a. Door LOCK/UNLOCK signal by smart key is received.
b. Tailgate open signal by smart key is received.
c. UNLOCK signal by door switch is received.
d. Tailgate open switch signal is received.
e. IGN ON signal is received.
f. Panic function is activated.
When the ignition is turned ON while the theft deterrent alarm is activated, the alarm is deactivated
immediately.
When the theft deterrent alarm is activated in theft deterrent mode, turning the ignition ON
immediately deactivates the mode. The alarm is deactivated 30 seconds (time remaining) after that.
If no deactivation command is received, the system enter the theft deterrent mode after the 30
seconds. -

Theft deterrent mode re-activation after tailgate open (for vehicles with SKM)
All doors except the tailgate are in theft deterrent mode, the system searches for the smart key inside the
vehicle 1 second after the tailgate is closed. If no smart key is found, the system enters the theft
deterrent mode again.
The hazard warning lamp and warning horn are activated when the system enters the mode.

When deleting the old code of the transponder registering an extra ignition key, please attend on
the site and observe the process personally.
In any cases, the immobilizer system cannot be removed from the vehicle. If you attempt to remove
it and damage the system, starting will be impossible. So never attempt to remove, damage or
modify it.
The remote engine starter cannot be installed to the vehicle equipped with the immobilizer system.
Do not drop the key or subject it to impact the key, as it may damage the transponder inside the
key.
The engine cannot be started using a key with damaged transponder.

1. OVERVIEW
The SKM (Smart Key Module) system is equipped to only the vehicles with smart key and is to prevent
theft and enhance the driver experience. When the driver presses a door handle switch carrying a smart
key, this system checks the smart key information and driver door status and locks/unlocks the doors
(passive function). The vehicle can be started when the driver enters the vehicle and presses the
START/STOP switch (passive start function).

(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. for up to 10
seconds. 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/STOP 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 seconds.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the B-CAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 seconds. -
-
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 B-CAN 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 B-CAN for up to 10 seconds until
the warning 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/STOP switch ON
input, the SKM sends the transponder verification status for 10 sec. -
