Operation Description
• When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote key-
less 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 lock/unlock signal to each door lock actuator.
• When the door lock actuators receive this signal, each operates to lock/unlock its door.
• BCM locks all doors with input of LOCK signal from keyfob.
• When an UNLOCK signal is sent from keyfob once, driver's door will be unlocked.
• Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, all other doors will be unlocked.
Remote control entry operation conditions
Auto Lock Function
Operation Description
• Unless the key is inserted into the ignition key cylinder, one of the doors is opened, or the keyfob is operated
within 1 minute after a door lock is unlocked by keyfob operation, all the doors are automatically locked.
The 1 minute timer count is executed by the BCM and after 1 minute, the BCM sends the lock signal to all
doors.
Lock operations are the same as for the remote control entry function.
Remote Control Automatic Back Door Function
Switching from all closed to all open
• When a button on the keyfob is operated, the signal is sent from the keyfob and received by the remote key-
less 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
open signal to the back door control unit
• When the back door control unit receives the back door open 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
unlock signal is sent to the back door latch using communication.
• When the back door latch receives the back door unlock signal, it operates the release actuator and
releases to back door latch.
• The back door control unit operates the back door motor to open the back door. (At this time, speed control,
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 key-
less 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 control.)
• 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-80
.
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.
