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.
