BACK DOOR AUTO CLOSURE SYSTEMPFP:90542
Component Parts and Harness Connector LocationNIS001OM
System DescriptionNIS001ON
When back door lock latch engaged with striker, striker is lowered by means of a motor the back door fully
closed.
CLOSE OPERATION

Half-latch is turned off when back door enters the state of a half door and back door closure control unit
recognizes it.

Back door closure control unit by which the signal is recognized operates closure motor in the close direc-
tion, and open switch is turned on.

Close switch is turned on when back door becomes a full latch position by operating closure motor and
back door closure control unit operates closure motor in an open direction.

The operation of closure motor is stopped, and back door enters all close states when back door moves in
an open direction, and open switch is turned off.
NON-OPERATION CONDITION

When you close back door while pushing back door opener switch.

When closing at once (within about 0.5 seconds) after back door is opened.
