(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the battery
cables with the ignition key turned to ON or ACC position, several electric units can be damaged
due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted with

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. -
