1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
Disconnect the negative cable from the battery
in advance when working on electrical units. -
If a fuse is blown, replace it with a fuse which
has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be
damaged or catch fire. -Do not drop or appy excessive impact to
sensors and relays. -
10 A 15 A
Make sure to turn "OFF" the ignition switch
and other lamp switches before disconnecting
or connecting the negative battery cable.
(Otherwise, semiconductor parts can be
damaged.)

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.

Theft deterrent mode deactivation conditions (for vehicles without SKM)
The REKES UNLOCK signal is input with IGN ON.
When the REKES UNLOCK signal is input in the theft deterrent mode or with the theft deterrent mode
deactivated, the hazard warning lamp is operated once and the theft deterrent mode is deactivated
(without warning horn output). -

Theft deterrent alarm deactivation conditions (for vehicles without SKM)
Any signal from the REKES (LOCK, UNLOCK, Panic, Escort) deactivates the theft deterrent
alarm.
The theft deterrent alarm remain on for up to 30 seconds.
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.
(For vehicles with immobilizer system, the alarm is deactivated once the key is verified after the
ignition is turned ON) -

Theft deterrent alarm deactivation conditions (for vehicles with SKM)
The theft deterrent alarm is deactivated in the following conditions. The theft deterrent mode is kept
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.

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.
