DOOR LOCK FUNCTION
Door Key Cylinder
Refer to DLK-53, "DOOR LOCK : CONSULT Function (BCM - DOOR LOCK)".
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The automatic door locks function is the function that locks all doors and fuel lid linked with the vehicle speed or shift position. It has 2 types as follows.
Vehicle Speed Sensing Auto Door Lock*1
All doors and fuel lid are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock and fuel lid actuators when it detects that the ignition switch is turned ON, all doors are closed and the vehicle speed received from the combination meter via CAN communication becomes 24 km/h (15 MPH) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door lock operation has taken place, the BCM will relock all doors when the vehicle speed reaches 24 km/h (15 MPH) or more again.
P Range Interlock Door Lock
All doors and fuel lid are locked when shifting the selector lever from the P position to any position other than P.
BCM outputs the lock signal to all door lock and fuel lid actuators when it detects that the ignition switch is in the ON position and the shift signal received from the TCM via CAN communication is shifted from the P position to any position other than P.
Setting change of Automatic Door Locks (LOCK) Function The LOCK operation setting of the automatic door locks function can be changed.
With CONSULT
The ON/OFF switching of the automatic door locks (LOCK) function and the type selection of the automatic door locks (LOCK) function can be performed at the WORK SUPPORT setting of CONSULT. Refer to DLK-53, "DOOR LOCK : CONSULT Function (BCM - DOOR LOCK)".
Without CONSULT
The automatic door locks (LOCK) function can be switched ON/OFF by performing the following operation.
OFF → ON : 2 blinks

AUTOMATIC DOOR LOCKS (UNLOCK OPERATION)
The automatic door locks (UNLOCK) function is the function that unlocks all doors and fuel lid linked with the key position or shift position. It has 2 types as follows.
IGN OFF Interlock Door Unlock*1
All doors and fuel lid are unlocked when the power supply position is changed from ON to OFF.
BCM outputs the unlock signal to all door lock and fuel lid actuators when it detects that the power supply position is changed from ignition switch ON to OFF.
P Range Interlock Door Unlock
All doors and fuel lid are unlocked when shifting the selector lever from any position other than the P to P position.
BCM outputs the unlock signal to all door lock and fuel lid actuators when it detects that the ignition switch is in the ON position and the shift signal received from TCM via CAN communication is shifted from any position other than the P to P position.
