INFOID:0000000001563459

BACK DOOR SWITCH : System Description

INFOID:0000000001563460

BACK DOOR RELEASE SWITCH OPERATION

The back door system consists of two units, the back door control unit and the back door cinching latch unit.
• Back door auto closure

When the back door is closed to the halfway state (half-latch) position, the motor automatically drives to
rotate the latch lever and pull it in from half latched to full latched.

OUTSIDE KEY ANTENNA DETECTION AREA

The outside key antenna detection area of back door open function
is in the range of approximately 80 cm (31.50 in) surrounding rear
bumper request switch (1). However, this operating range depends
on the ambient conditions.

OPERATION DESCRIPTION

Back Door Release Switch Opening Operation

• When the back door release switch is pressed, the Intelligent Key unit terminal 24 receives signal from the

back door release switch terminal 1.

• The back door control unit checks the park/neutral switch position and vehicle speed. If the back door oper-

ating enable conditions are met, it sends a signal through terminal 23 to the back door control unit terminal 6.

• When the back door control unit receives the signal, if the back door operating enable conditions are met, it

sends a signal through terminals 2 and 3 to operate the cinch latch motor to open the back door to the half-
latch position.

• When the back door reaches the half-latch state, the half-latch switch detects this and the signal is sent to

the back door control unit terminal 7. Continue to press the back door release switch and pull the back door
to the full open position.

• When the back door is open, the neutral position sends a signal to the back door control unit terminal 9.

Back Door Release Switch Closing Operation

• When the back door is pulled toward the close position and when it reaches half-latch, the back door cinch-

ing latch unit half switch sends a signal from terminal 6.

• The back door control unit receives this signal and checks door position through terminal 7.

• When the back door control unit receives the signal, if the back door operating enable conditions are met, it

sends a signal through terminals 2 and 3 to operate the cinch latch motor to close the back door.

• When the back door latch operates and full close is detected through terminal 8 of the back door control unit,

the cinch latch motor reverses to the neutral position and the back door auto closure operation ends and the
door is fully closed.
