OK >> Door unlock sensor is OK.
NG >> GO TO 2.
2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect BCM and front door lock assembly (driver side) connector.
3. Check continuity between BCM connector M3 terminal 7 and
front door lock assembly (driver side) connector D24 terminal 4.
4. Check continuity between BCM connector M3 terminal 8 and
ground.

Intelligent Key Lock-in Prevention Function
When Intelligent Key is in vehicle, a door is open, and doors are locked using door lock and unlock switch,
driver door lock knob, Intelligent Key unit sends door unlock request signal to BCM via CAN communication to
unlock all doors to prevent Intelligent Key from becoming locked in vehicle.
When Intelligent Key is in trunk room, all doors are lock and trunk lid is closed, Intelligent Key unit sends trunk
open signal to BCM. Then BCM open trunk lid and warning buzzer sounds for 10 seconds.
CAUTION:
The above function operates when the Intelligent Key is inside the vehicle. However, there may be
times when Intelligent Key cannot be detected and this function will not operate when Intelligent Key
is on the instrument panel, rear parcel shelf, or in the glove box. Also, this system some times does
not operate if the Intelligent Key is in the door pocket for the open door.
List of Operation Related Parts
Parts marked with × are the parts related to operation.
REMOTE KEYLESS ENTRY FUNCTIONS
Door Lock/Unlock Function

Operating a remote controller button on the Intelligent Key sends the Intelligent Key-ID to the Intelligent
Key unit. Intelligent Key unit conducts a verification of the received key-ID, and if the verification is
accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door lock.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
Trunk Open Function

Operating a remote controller button on the Intelligent Key sends the Intelligent Key-ID to the Intelligent
Key unit.

Intelligent Key unit conducts a verification of the received key-ID, and if the verification is accepted, a
trunk open request signal is sent to BCM via CAN communication trunk lid is opened.
