SECTION 4C - VT SERIES SUNROOF
CAUTION:
This vehicle will be equipped with a Supplemental Restraint System (SRS). A SRS will consist of
either seat belt pre-tension ers and a driver’s air bag , seat belt pre-t ensioners and a driv er’s and front
passenger’s air bag s or seat belt pre-tensio ners, driver’s and fron t passenger’s air bags and left and
right hand side air bags. Depending upon the system fitted, refer to SAFETY PRECAUTIONS, Section
12M Supplemental Restraint System in the VT Series I Service Information, before performing any
service operation on or around any SRS components, the steering mechanism or wiring. Failure to
follow the SAFETY PRECAUTIONS could result in SRS deployment, resulting in possible personal
injury or unnecessary SRS system repairs.
CAUTION:
This v ehicle may be equipped w ith LPG ( Liquefied Pet roleum Gas). In th e interests of safet y, the LPG
fuel system should be isolated by turning 'OFF' the manual service valve and then draining the LPG
service lines, before any service work is carried out on the vehicle. Refer to the LPG leaflet included
with the Owner's Handbook for details or in the VT Series I Service Information for more specific
servicing information.
1. GENERAL INFORMATION
This Section of the Holden By Design Service Infor mation Supplem ent describes the ser vice procedures f or the
HBD sunroof available for VT Series Vehicles.
The sunroof is an electrically operated, two-way sliding and tilting type. It features a tinted glass panel with an
internal sliding sunshade and has a front edge wind deflector. The sunroof is operated by a rocker switch,
centrally located in the vehicle's headlining, forward of the sunroof aperture. A Sunroof Control Unit (SCU)
provides several pre-programmed functions and the facility to program an additional option.
PRE-PROGRAMMED FUNCTIONS
Soft Touch
By a single touch of the switch, the roof can be fully opened to the maxim um tilt position or the maximum slide
position.
Variable Tilt Position
The panel can be closed from tilt in four steps by continuously pressing the switch and releasing in the desired
position.
Jamming Protection (safety feature)
W hen closing the s unroof by soft touch or auto-c lose, the sunroof will autom atically re-open when it encounters
an obstacle. The roof will then attempt to re-close until the obstacle is removed.
Auto-Close Function
Three seconds after switching off the ignition the sunroof will close automatically. This can be prevented by
pressing the switch once within three seconds of the ignition being switched off.
One-Way Closing
This feature always closes the glass panel from above, assuring a flush fit of the panel.
OPTIONAL PROGRAMMABLE FUNCTION
Comfort Position In The Sliding Range
This feature allows a preset stopping position of the glass panel in the sliding range of the sunroof to be
programmed. The glass panel will stop at the preset position when opened via the soft touch operation.
1.1 GENERAL DESCRIPTION
GLASS PANEL MOVEMENT
Movement of the glass panel into the tilt and slide positions is controlled by the following functions.
Continuous Control
Press the switch longer than 0.3 second:
Full control over the glass panel movement in the slide position.
Releasing the switch will stop the glass panel movement.
A full stop in maximum slide and closed position.
Four Steps Down Tilt Adjustment
Press the switch longer than 0.3 second:
When closing the sunroof from maximum tilt position by pressing the switch continuously, the glass panel
will stop briefly in four intermediate positions.
Releasing the switch will stop the glass panel movement.
To continue the stepped operation, press the switch again.
One Touch Control
Press and release the switch within 0.3 second:
Automatic glass panel movement towards full open or full closed position (slide and tilt).
Anti-jamming protection while closing.
The glass panel movement can be interrupted by pressing the switch.
Auto-Close
When the ignition is switched off, the glass panel will close after a three second delay:
Anti-jamming protection while closing.
Pressing the switch within three seconds after the ignition switch off will cancel auto-close.
One Way Closing
To ens ure correc t positioning of the glas s panel after c losing, it will always close from above, even when closed
from a slide position.
INTERIOR TRIM
Sunshade
Sunshade operation depends on glass panel movement as follows:
Moving the glass panel to tilt position, the sunshade automatically opens to a vent position and can be
moved to full open position by hand.
Moving the glass panel into slide position, the s unshade will move together and can also be fur ther opened
by hand.
Closing the sunshade m ust be perfor med m anually. It can only be closed c ompletely when the glass panel
is in the closed position.
Wind Deflector
The wind deflector automatically raises when the glass panel m oves into sliding position and retracts when the
glass panel closes again.
The Holden By Design sunroof major components are shown in Fig. 4C-1.

2. SERVICE OPERATIONS
The following service operations for the Holden By Design sunroof are those that can be performed by the
general service technician. The procedure for the removal and installation of the sunroof assembly has
deliberately been omitted due to the skills and special tools required, which would be beyond the scope of the
general repair technician. Also, as the sunroof assembly is chemically bonded to the vehicle’s roof panel,
damage to the sunroof and roof panel will result if rem oval is perf orm ed, necessitating s unroof replac ement and
roof panel repair.
NOTE: W here a sunroof is fitted, a new headlining is created using pieces of the original headlining and a new
sheet of c loth. The headlining is then installed with adhesive. Rem oval m ay damage the headlining and extr em e
care is required.
If assist ance is required in the servic ing or installation of the s unroof as sembly, contact the authoris ed Hollandia
sunroof specialist in your area or contact Hollandia Sunroofs Australasia on (02) 9540 4811.

3.2 TESTING ELECTRICAL COMPONENTS
Ensure that during testing electrical components, the sunroof is connected to a power source supplying 12 to
14 V. If the Sunroof is installed, the battery needs to be connected and operable. During testing, the ignition/
accessory switch should be on. This test can be accomplished with a test light or multimeter and by using the
wiring schematic in Fig. 4C-11 as a guide.
NOTE: Harness and drive motor inspection requires at least part of the headlining to be removed.
FUSES
Visually inspect the fuses for damage and replace as required.
WIRING HARNESS
Check for correct power supply on the Red and White (Black early models) wires. Inspect for broken or
damaged wires. Inspect for secure connection to the SCU.
SWITCH
Inspect for correct power supply to the sunroof operating switch, accomplished by using a test light on the
connector at the switch bracket. Operate the switch connector to assure movement in front and rear sliding
positions.
DRIVE MOTOR
Disconnect the drive motor wire (Green/Black) from the sunroof control unit. Remove the drive motor. Using a
double wire of sufficient length, connect direct to the battery.
Check the drive motor for correct operation in both directions. This is accomplished by reversing the connection
of the double wire.
The drive motor has an in-built thermal cut-out device that automatically sw itches the drive motor off during
periods of overload. After a cooling down period, the drive motor will function properly.
