1. GENERAL DESCRIPTION
This section describes the service procedures required for the factory fitted (Online) sunroof installed in MY 2003
VY Series Sedans.
The Online sunroof can be identified by the presence of a rigid headlining and the absence of a rubber trim ring
between the sunroof and the roof panel.
The Online sunroof is an electronically operated, two-way design allowing either tilting or sliding ac tions. It features
tinted glass with a separate internal s unshade and a f ront edge wind deflector . T he sunroof is operated via a s witch
panel located in the roof console, for ward of the sunroof opening. The Sunroof Control Unit (SCU) provides several
pre-programmed functions and the option to program an additional function.
PRE-PROGRAMMED FUNCTIONS
NOTE: If only the sunroof switch button ! and button
" are operating, the sunroof switch has to be reset,
refer to 2.20 SUNROOF SWITCH.
SOFT TOUCH
With the ignition switch ON, briefly pressing the
sunroof button ! will open the sunroof to the
maximum slide position. Briefly pressing the sunroof
button " will open the sunroof to the maximum tilt
position. Movement of the sunroof can be stopped at
any time by briefly pressing the button ! or " again.
CLOSING THE SUNROOF
Briefly pressing the button C will cause the sunroof to
close from any open position.
VARIABLE TILT POSITION
NOTE: Sunroofs installed until June 2003 can be
opened to four tilt positions, sunroofs installed after
June 2003 open to three tilt positions only.
The sunroof can be lowered from maximum tilt
opening in three/four intermediate tilt positions. Press
and hold the sunroof button ! until the glass panel
reaches the next tilt position. Alternatively, hold the
button pressed and then r elease it at the desired glass
panel tilt position.
Figure 1F-1
JAMMING PROTECTION (SA FETY FEATURE)
W hen c losing the sunroof using Soft T ouch or Auto-C lose, the sunroof will automatically re-open if it enc ounters
an obstacle and then try to close again. This cycle will continue until the obstacle is removed.
AUTO-CLOSE FUNCTION
Three seconds after the ignition has been turned OFF, the sunroof will close automatically. To override this
action, brief ly pres s the sunroof button ! or " when the sunroof has r eached the desired position or during the
three second interval to maintain the sunroof position, refer to Figure 1F-1.
The sunroof can be closed when the ignition is OFF but it cannot be opened.
ONE-WAY CLOSING
This automatic f eatur e always closes the sunroof from above lowering the glass panel to the close position, even
when closed from a slide position, assuring correct positioning of the glass panel.
OPTIONAL PROGRAMMABLE FUNCTION
COMFORT POSITION
This feature allows the sunroof to be opened to two preset positions in the sliding range.
PROGRAMMING THE COMFORT POSITION
To program the two preset positions:
1. Position the sunroof in the desired location.
2. Press and hold button 1 until a beep is heard (approx. 3 seconds).
3. Position the sunroof in the second desired location.
4. Press and hold button 2 until a beep is heard (approx. 3 seconds).
Refer to Figure 1F-1.
To select either preset position, press button 1 or 2. (Pressing either button again will open the sunroof fully).
INTERIOR TRIM
SUNSHADE
The sunshade c an be opened and closed manually when the sunroof is closed but is c ontrolled autom atically in
the following conditions:
• Opening the sunroof in a tilt pos ition automatically opens the sunshade to a vent position. The sunshade can
then be fully opened manually.
• When the sunroof is opened in slide m ode, the s unshade opens along with it. T he sunshade c an be opened
further manually.
The sunshade can only be closed fully w hen the sunroof is closed, and can only be closed manually.
WIND DEFLECTOR
The wind deflector is designed to reduce high frequency noise. The wind deflector automatically rises when the
sunroof is opened in slide mode. It retracts when the sunroof is closed. A stopper on either side of the wind
deflector is controlling the height at which the wind deflector is raising.
GLASS PANEL
The sunroof glass panel is heat and UV resistant. Clean the glass panel using mild, non-scratching detergent
and a chamois.
RUBBER SEAL
Two types of rubber seal can be fitted to the glass panel assembly. They both have the same function despite
the physical and cross-section differences.
The first r ubber seal type can be identified by its outer surfac e of velvet-like appear ance. The outer edge of the
seal body is open- ended to allow adjus tm ents, with foam st rips, that m ay be necessary to ensure proper s ealing
when the glass panel is in the closed position.
The second rubber seal type is an optional design to the first type and can be identified by its outer surface of
smooth appearance. The outer section of the seal body is hollow with the external surface covered by an anti-
friction coating. No adjustment is necessary for this rubber seal type.
SUNROOF CONTROL UNIT (SCU)
The SCU is located at the rear of the sunr oof fram e and controls a drive m otor to activate the m ovement of the
glass panel.
The SCU detec ts the position of the glass panel by using an internal position counter. This counter is inc reased
and decreased every time the SCU controls the drive motor.
The c ounter mus t first be s et (calibrated) to detec t the end position of the glas s panel, in full tilt and full slide, by
running to a mechanical block.
If the SCU determines that the glas s panel is in the inc orr ec t pos ition, as def ined by the internal position counter,
it responds by entering the non-calibrated state.

LT Section No. -
INTRODUCTION
The s unroof is operated via a contr ol unit and a switch. T he control unit and the s witch are connec ted to each other
by two harnes ses that each have s ix wires. The glas s panel is activated by a drive motor which is connected to the
control unit. Battery voltage is supplied to the control unit through the ignition switch in the ON position or a circuit
break er when the ignition switch is in the OF F position. These tes ts c onf ir m the cor rec t oper ation of the sunroof and
the serviceability of the switch, the control unit, the drive motor and associated circuits. For a complete wiring
diagram of the sunroof circuits , refer to 3.2 WIRING DIAGRAM S - SUNROOF. For connec tor pin locations , refer to
3.3 CONNECTOR DIAGRAMS - SUNROOF.
NOTE 1: The drive motor has an inbuilt thermal cut-out device that automatically switches the motor off during
period of overload. After a cool down period, the motor will function normally again.
NOTE 2: If the SCU fails and is replaced with a new unit, the first time the new SCU is connected to the power
supply it must be calibrated, refer to 2.4 CALIBRATING THE SUNROOF CONTROL UNIT.
NOTE 3: On completion of the electrical test and/or if the situation arise where only the sunroof switch button ! and
