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. -

Smart key searching
* Theft deterrent mode: deactivated after searching the outside vehicle
* Theft deterrent mode deactivated: outside searching after inside searching -
-
-The driver door is locked and the system in the theft deterrent mode.
The tailgate open switch signal is received.
The BCM sends the valid smart key verification request signal to the SKM.
The SKM verifies if a smart key is outside the vehicle using the corresponding rear bumper antenna
(LF verification) (The SKM searches the last smart key used first. If a valid smart key searching is
completed, searching for a key in the luggage compartment and inside the vehicle is started).
The verification signal (RF verification) from the smart key is sent to the REKES antenna of the SKM.
The SKM sends the Passive tailgate open signal to the BCM through the B-CAN if the verified smart
key is found outside the vehicle.
The BCM activates the tailgate open relay according to the signal received from the SKM.
(Only the theft deterrent mode for tailgate is deactivated.) -
