Item Description 1 Battery 2 Megafuse (250 A) 3 Rear window sunblind, switch 4 Rear window sunblind, motor 5 ABS (anti-lock brake system) module 6 Roof opening panel, control module 7 Roof opening panel, rocker switch 8 CJB (central junction box)

Roof opening panel System Operation

Operation of the roof opening panel is controlled by the roof opening panel control module, which is integral with the motor.
The control module receives inputs from the CJB, which provides an 'open' or 'close' signal for remote handset operation, and
an 'enable' signal when the vehicle enters power mode 6.

The control module also receives a vehicle speed signal from the ABS module. The vehicle speed signal is used by the control
module to calibrate the anti-trap feature.

If the battery is disconnected, or the power supply is interrupted while the roof opening panel is in a partially open position,
the motor and control module will need to be calibrated to restore full functionality. To recalibrate:
1. Switch ignition on.
2. Press the front of the switch, so the roof opening panel is the tilt position, and then release the switch.
3. Press the front of the switch and hold for thirty seconds.
4. After thirty seconds the roof opening panel will begin to move. Keep the front of the switch pressed until the roof
opening panel has fully opened and then closed.
5. Once the open/close cycle has completed and the roof opening panel has stopped moving, release the switch.
6. The roof opening panel can now be operated as normal.

Drain hoses are connected to the front and rear corners of the roof opening panel frame. The drain hoses are located inside of
the cabin on the 'A' and 'D' post pillars to allow water, which has collected in the frame, to escape. One-way valves fitted to
the end of each drain hose, prevent the ingress of dirt and moisture.

Rear window sunblind

The powered rear window sunblind is operated through a switch in the roof console. Power to the sunblind motor is provided by
a pair of relays located in the CJB when the vehicle enters power mode 4. The sunblind motor is located beneath the rear parcel
shelf and is supplied as a sealed unit with the sunblind mechanism.

If the battery is disconnected or a replacement sunblind is fitted, the motor will require re-calibrating. To re-calibrate the
motor the sunblind should be powered through two-full cycles of movement.



Roof opening panel, motor Component Description

The roof opening panel motor has a worm drive which drives a gear in the 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 two 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 of
each cable is held in position on the pinion by a metal insert in the frame. The cables run in channels, in the panel frame to
the guides. As the panel is closed the cables are pushed through channels in the front of the frame. The displaced cable is
guided into a further two channels in the frame, which protect the cable and prevent it from snagging. The cables
manufactured from rigid spring steel can pull as well as push the panel along the guides.

The motor contains a micro-switch and Hall effect sensor. Signals received from these components enable the control module
to calculate the exact position of the roof opening panel. The Hall effect sensor is also responsible for the operation of the
anti-trap function.

If the anti-trap feature is activated while the roof opening panel is closing, the panel is reversed for 200mm or as far as
possible. The Hall effect sensor, located in the motor, monitors the speed of the motor and if the speed decreases below a set
threshold, indicating an obstruction, the power feed to the motor is reversed so the panel goes back. In an emergency the
anti-trap function can be overridden by holding the switch in the closed position.

Roof opening panel, control module

The roof opening panel control module is integrated within the motor. The control module receives inputs from the CJB, which
provides an 'open' or 'close' signal for remote handset operation, and an 'enable' signal when the vehicle enters power mode 6.

The control module also contains the algorithm for the anti-trap system and receives a vehicle speed signal from the ABS
module. The vehicle speed signal is used by the control module to calibrate the anti-trap feature.

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Roof opening panel
Helixed drive cables
Switch
Control unit/motor
Fuses/relays (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
