LR3/Disco 3
vehicle is unlocked, the CJB (central junction box) reverses the lock and superlock motors, to re-engage the release
cables, by changing the polarity of their power and ground connections. To enable the SPE (single point entry) function,
the lock motor in the driver door latch is operated by two dedicated connections with the CJB (central junction box) ; the
lock motors in the other three doors are all operated by two (other) common connections with the CJB (central junction
box) . The superlock motors in all four door latches are all operated by two common connections with the CJB (central
junction box) .
All of the interior door handles incorporate a locking button. Pressing the front of the locking button pushes the interior
release cable, which causes the door latch to disengage from the exterior release cable. On the rear doors, the button
also disengages the interior handle from the interior release cable.
Pulling the front of the locking button out again re-engages the interior door handle with the interior release cable, and
also pulls on the interior release cable. This causes the door latch to re-engage with the exterior release cable.
Child Locks
Child Lock and Label
Each rear door incorporates a child lock. The child lock controls the engagement of the interior release lever with the latch
mechanism. When a child lock is set to the locked position, the interior release lever is disengaged from the latch
mechanism, which prevents the door being opened with the interior door handle.
Each child lock is operated by installing the ignition key in an aperture in the inner skin of the rear door, where the ignition
key engages with the child lock barrel on the door latch. Turning the ignition key sets the child lock to the locked or
unlocked position, as detailed on the instruction label installed immediately above the child lock aperture.
