The back door control unit operates the back door motor to open the back door. (At this time, speed con-
trol, input reverse, and overload reverse control are executed.)
When the back door is opened to the fully open position, the full-open position is detected with the rotation
sensor, the back door motor is stopped.
The door held by the back door stays at the full open position.
Full open → full closed operation
When a button of the keyfob is operated, the signal is sent from the keyfob and received by the remote
keyless entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM uses power window serial link communication to send the back door
close request signal to the back door control unit.
When the back door control unit receives the back door close request signal for 0.5 seconds, if the remote
control automatic back door operation enable conditions are met, the warning chime is sounded and the
back door motor begins closing the back door.
The back door control unit operates the magnetic clutch and the back door motor to close the back door.
(At this time, the back door control unit executes speed control, input reverse, and overload reverse con-
trol.)
When the back door comes to the half-latch state, the back door latch detects the half-latch state through
half-latch switch operation. The back door latch latches the back door.
For the automatic back door system operation enable conditions, refer to BL-99, "
AUTOMATIC BACK DOOR
SYSTEM" .
Active Check Function
Operation Description
When a door is locked or unlocked by keyfob operation, the vehicle turn signals flash and the horn sounds to
verify operation.
When a button on the keyfob is operated, the signal is sent from the remote controller and received by the
keyless remote entry receiver.
The received signal is sent to the BCM and compared with the registered ID number.
If the ID number matches, the BCM sends the turn signal flashing and horn signal to the IPDM E/R.
The IPDM E/R flashes the turn signal lamps and sounds the horn for each keyfob operation.
