- The roof opening glass will close until the roof opening panel switch is pressed in any direction or the roof opening glass
reaches the full closed position.

Press the rear of the switch to the first detent with the roof opening glass in a vent up position.

- The roof opening glass will close until the roof opening panel switch is released or the roof opening glass reaches the full closed
position.

Press the rear of the switch to the second detent with the roof opening glass in a vent up position.

- The roof opening glass will close until the roof opening panel switch is pressed in any direction or the roof opening glass
reaches the full closed position.

Global Closing Operation

The roof opening panel is included in the global close operation. This function closes the power windows and the roof opening panel
automatically. For additional information on the global close feature for the power windows, refer to Section

501-11 Glass, Frames and

Mechanisms

.

The global close function is activated by:

turning the driver door lock cylinder to the lock position and holding.

Global close operation is only available with the ignition in the OFF position and the ignition key removed.

When the global close operation is selected, the roof opening panel switch is not recognized by the roof opening panel control module
throughout the operation and for five seconds after the operation is completed.

Global close will operate as follows.

With the roof opening glass in the open position, activating global close will close the roof opening glass to the flush position.

Diagnosis and Testing

Principles of Operation

Roof Opening Panel Control Module

Battery power is continuously supplied to the roof opening panel control module. However, the roof opening panel will only operate from the
roof opening panel switch with the ignition switch in the RUN or ACCY position. The global close feature is controlled by two circuits from
the generic electronics control module (GEM). The two circuits must be at ground potential before the roof opening panel control module will
acknowledge the roof opening panel switch. When the ignition switch is turned to RUN or ACCY, the GEM provides ground to these circuits.

The roof opening panel control module incorporates soft stops at the end of all travel positions. The roof opening panel control module
monitors the internal switches to determine the roof opening glass position and the soft stops. The internal switches are activated by the
roof opening panel motor rotation.

The roof opening panel control module supplies the power and ground to the roof opening panel motor depending on the ordered function.
Power is supplied to the roof opening panel for a maximum of 12 seconds. Under normal operation, position is monitored by the roof
opening panel control module and power is removed from the roof opening panel motor as soon as the roof opening panel reaches the
commanded position.

Roof Opening Panel Switch

Two circuits connect the roof opening panel switch to the roof opening panel control module. One circuit controls open and down operation.
The other circuit controls the tilt and close operation. The roof opening panel control module monitors these lines for voltage fluctuation to
determine which function was selected.

With the ignition switch in the RUN or ACCY position, the roof opening panel supplies a five volt reference voltage to three control lines.
Activation of the roof opening panel switch connects one or more of these lines to the common return which pulls the line low. The roof
opening panel control module will sense the line or lines being connected to the common line and carry out the appropriate function.

The express open function connects the open and tilt circuits to the common return when the roof opening panel switch is moved rearward
to the second detent position. The operator-controlled open function connects the open circuit to the common return. The close function
connects the close circuit to the common causing the roof opening panel to close from a slide or vent position.

Global Close

One circuit connects the GEM to the roof opening panel control module for this function. Global close operation for the roof opening panel is
controlled by this circuit being grounded by the GEM.

When the ignition switch is in the RUN or ACCY position, the GEM grounds this circuit allowing normal operation of the roof opening panel
from the roof opening panel switch. Global close operation is only available with the ignition in the OFF position and the ignition key
removed.

When global close operation is selected, the roof opening panel switch is not recognized by the roof opening panel control module
throughout the operation and for five seconds after the operation is completed.

With the ignition switch in the OFF position, the roof opening panel control module supplies a constant voltage to this circuit. The roof
opening panel control module monitors these lines for a low state, caused by the GEM grounding the line, to determine the ordered global
function by the GEM.

Global close is commanded by the GEM grounding control line one. Line two will remain at previous voltage.

If both lines have voltage, the roof opening panel will be inoperative.
