OPEN OPERATION

• When the back door opener switch operation signal is input into back door control unit from BCM, back door

is opened by the closure motor open operation.

• When back door opener switch is pressed, BCM transmits the back door open request signal to back door

control unit and back door control unit opens back door.

• The operation to open back door with Intelligent Key is the same as the Intelligent Key system. Refer to

DLK-42, "BACK DOOR OPEN FUNCTION : System Description"

Operation Condition

If the following conditions are satisfied, the back door opener operation is performed.

NOTE:
• When battery terminal is disconnected and reconnected during all doors unlock state, back door may not

open.

• Regardless of door lock actuator state, BCM resets recognition of all doors unlock state approximately 30

seconds after battery terminal is disconnected and BCM recognizes that all doors are in lock state.

• When battery terminal is reconnected and back door does not open, have BCM recognize that all doors are

in unlock state.
