OPERATION ENABLE CONDITION

*: If the registered Intelligent Key is used, the operation can be performed even if the back door is in the LOCK position

CONTROL IF NOT WITHIN THE OPERATION CONDITIONS DURING THE OPERATION

If the back door is not within the operation conditions during the operation, the automatic back door control unit
performs the control as follows.

Function

Description

Automatic back door open/close
function

In the case of the back door fully closed, operate the automatic back door switch, Intelligent Key
bottom or back door opener switch with the back door unlock. The back door closure motor re-
leases the latch, then the automatic back door motor opens the back door to the fully open po-
sition. Reverse the closure motor to the neutral position simultaneously.
In the case of the back door fully open, operate the automatic back door switch, Intelligent Key
bottom or back door close switch. The automatic back door motor closes the back door to the
half-latch position, then the back door closure motor closes to the full latch position. Then, re-
verse the closure motor to the neutral position.
NOTE:
When the main switch is OFF, the power operation is not available by back door opener switch
and automatic back door close switch.

Back door auto closure function

When the back door is closed to the half-latch position, the motor drives to rotate the latch lever
and pulls it in from half latched to fully latched and automatically closes the door. Then, reverse
the closure motor to the neutral position.

Anti-pinch function

During auto operation, if an object is detected by encoder pulse or touch sensor in the door's
path, a warning chime sounds and the back door operates in the reverse direction to prevent
pinching.

Intermittent clutch function

If the main switch is turned to OFF during auto operation, the back door may be closed suddenly
because the operation is interrupted immediately when the operation cannot be continued be-
cause of the detection of a system malfunction. Therefore, operate the clutch intermittently to
stabilize the back door behavior and ensure safety.
