2 DESCRIPTION AND OPERATION
DESCRIPTION
The sunroof is electrically operated through a rocker
switch located on the centre console. An electric
motor, attached to the sunroof frame, drives the glass
sunroof panel to the tilt or open positions. The glass
panel is operated by two cables which are driven by
the motor.
The sunroof frame is bolted to eight mounting points
on the roof panel. The frame is constructed from
pressed steel and supports all of the sunroof
components. A bracket at the front of the frame
provides an attachment point for the sunroof motor.
The motor is supported on the frame with three
spacers and secured with three self tapping screws.
A guide is fitted to each side of the sunroof frame.
Each guide has an attachment at its forward end for
the sunroof panel. The rear of the panel is attached to
each guide on levers which operate the tilt function.
The forward attachments and the levers slide in the
guide to allow the panel to move in the desired
position. Each lever has a peg located in a curved slot
in the guide.
The sunroof motor has a worm drive which drives a
gear in a cast housing attached to the end of the
motor. The gear has a small pinion gear attached to
the outer part of its spindle. The pinion engages with
the spiral cables to form a rack and pinion drive.
Rotation of the motor turns the pinion which in turn
drives the cables in the required direction.
The two cables are attached either side of the pinion.
One end of each cable is attached to the guide. The
opposite end is clamped in its position on the pinion
by a riveted bracket. The cables run in metal tubes to
the guides. As the sunroof panel is closed, the cables
are pulled through the metal tubes. The displaced
cable is guided into plastic tubes which protect the
cable and prevent the cable snagging. The cables are
made from rigid spring steel and therefore can push
as well as pull the sunroof along the guides.
A sunshade is also located in the guides. When the
sunroof panel is closed or tilted, the sunshade can be
retracted or pulled forward to cover the sunroof panel.
When the sunroof panel is opened, two brackets on
the sunshade engage with the panel as it is retracted.
The sunshade is then pulled back by the retracting
panel. When the panel is closed, the sunshade
remains retracted until pulled manually to its closed
position.
Drain hoses are connected to the front and rear
corners of the frame. The drain hoses are located
inside the ’A’ and ’D’ post pillars to allow water which
has collected in the frame to escape. A one way valve
is fitted to the end of each drain hose to prevent the

inside the ’A’ and ’D’ post pillars to allow water which
has collected in the frame to escape. A one way valve
is fitted to the end of each drain hose to prevent the
ingress of dirt and moisture.
OPERATION
The sunroof can be operated with the ignition switch
in position I or II. The sunroof can also be operated for
up to 45 seconds after the ignition is switched off
provided the driver’s door is not opened. When the
driver’s door is opened, a further 45 second period
commences. During the 45 second period the one
touch function is inoperative.
If a failure of the sunroof motor occurs for whatever
reason, the sunroof can be closed manually. Removal
of the interior courtesy lamp allows the fitment of a
special key into a slot in the motor drive. The sunroof
can then be manually driven to the closed position.
The motor contains a microswitch and a Hall effect
sensor. Two gears, driven by the motor at one end of
the pinion drive spindle, trip the microswitch every
thirteen revolutions of the spindle. When the
microswitch is tripped, an open circuit signal is sensed
by the Body electrical Control Module (BeCM). The
signal from the microswitch, combined with signals
received from the Hall effect sensor, are used by the
BeCM to calculate the exact position of the sunroof.
The Hall effect sensor is also responsible for the
operation of the anti-trap function.
Tilt Operation
With the sunroof panel closed, pushing the lower part
of the rocker switch operates the sunroof motor to ’tilt’
the rear of the sunroof upwards. The motor operates
for as long as the switch is operated until the glass is
tilted to its full extent. If the switch is released before
the full tilt position is reached, the sunroof panel stops
at the chosen position.
When the tilt function is requested, the cables pull the
guide forward, forcing the peg on each lever to move
in the slot which raises the sunroof panel to the tilt
position.
With the sunroof panel in the tilted position, pushing
the upper part of the rocker switch, operates the
sunroof motor to lower the sunroof panel. The motor
operates to lower the panel for as long as the switch is
operated until the panel is fully lowered. If the switch
is released before the fully lowered position is
reached, the sunroof panel stops at the chosen
position.
Open (slide) Operation
With the sunroof panel closed, pushing the upper part
of the rocker switch operates the sunroof motor to
lower the sunroof panel and retract it backwards. If the
switch is held, the motor operates until the switch is
released or the panel reaches its fully open position. If
the switch is pushed momentarily (less than 0.5
seconds), the panel will retract automatically to a half
open position. A second short push on the switch will
automatically retract the panel fully. When the panel
retracts, a wind deflector automatically raises at the
front of the sunroof aperture which serves to reduce
wind noise.
When the open function is requested, the cables pull
the guide in a rearward direction, forcing the peg on
the lever to move in the slot which lowers the rear of
the sunroof panel below the roof. As the panel begins
to move, the forward panel attachments slide down a
ramp in the guide, lowering the forward end of the
panel below the roof.
With the sunroof panel half or fully open, pushing the
lower part of the switch operates the motor to close
the sunroof panel. If the switch is held, the panel
closes until the switch is released or the panel
reaches its fully closed position. If the switch is
pushed momentarily (less than 0.5 seconds), the
panel will close automatically until it reaches the half
open position. A second short push on the switch will
automatically close the panel fully.
The sunroof has an ’anti-trap’ function which prevents
the sunroof panel from closing if an obstruction is
sensed. When an obstruction is sensed, the motor will
automatically retract the panel to the half or fully open
position. A message ’SUNROOF BLOCKED’ is
displayed on the message centre in the instrument
pack. When the obstruction is removed, the panel can
be closed by the normal method.
Battery Disconnection
If the battery has been disconnected, the one touch
and anti-trap function will become inoperative. These
functions can be reset by fully opening and closing,
then fully tilting and closing the sunroof panel in one
continuous operation. An audible warning will sound
and ’SUNROOF NOT SET’ will be displayed on the
message centre in the instrument pack when the
sunroof is being operated.
When the above procedure has been successfully
completed, an audible warning will sound and
in position I or II. The sunroof can also be operated for
up to 45 seconds after the ignition is switched off
provided the driver’s door is not opened. When the
driver’s door is opened, a further 45 second period
commences. During the 45 second period the one
touch function is inoperative.
If a failure of the sunroof motor occurs for whatever
reason, the sunroof can be closed manually. Removal
of the interior courtesy lamp allows the fitment of a
special key into a slot in the motor drive. The sunroof
can then be manually driven to the closed position.

Welcome to the board Alan. Quick suggestion.... go to the 'user cp' section of the site (which can be found at the top of the thread near the 'new reply' button) and edit your signature in order to put the year and model of your truck in there so that it is easier to know quickly what truck you have when you (inevitably) need help.
