The power sunroof (CF5 option) has the following features:
| • | A manually operated sunshade. A recess is provided in the sunshade to
be used to push the shade open or pull it shut. |
| • | An express module at the front of the sunroof control module, allows the
window panel to stop in the closed, vent and fully open positions. |
| • | The Sunroof Opening Position Switch (SOPS) contains the limit switches
for the window panel operation. Its gearing drives the window into the desired position.
The window panel must be in the closed position when this unit is replaced. |
| • | The sunroof motor actuator attaches to the SOPS and contains the driveshaft
that drives the gearing in the SOPS. This driveshaft will turn infinitely in both
directions. |
| • | The power sunroof switch is a two position rocker type switch which electrically
operates the power sunroof. The switch is located in the headliner in front of the
sunroof. Press and hold the front indent position to move the sunroof glass to the
vent position. Press and hold rear indent and the sunroof will return to the full
closed position. |
| | Press rear indent once and the sunroof glass will slide to the full open position
automatically (express open). |
| | Press and hold the front indent position on the control switch in order to close
the sunroof window from the open position. The switch must be held until the window
reaches a desired position or until it closes completely. |
| • | A drain trough is positioned under the sunroof glass panel. Water is collected
by this trough and is drained off by drain hoses connected at each corner. |
| • | The glass panel seal fits around the glass panel and is used to seal the
opening between the glass panel and the roof panel. |
| • | The sunroof electrical harness is routed to join the body harness at the
right rear pillar. |
Power Sunroof System Components
The power sunroof system consists of the following components:
| • | Sunroof Opening Position Switch (SOPS) |
| • | Sunroof glass (tilt/slide type, with glass sliding between roof and headliner) |
| • | Rail and track assembly upon which the sunroof glass rides |
| • | Power supply for the sunroof control module: PWR WINDOWS PWR SUN ROOF
30 A circuit breaker |
Power Sunroof Operation
The power sunroof will operate with the ignition switch turned to Accessory
or RUN. Once the ignition switch is turned to OFF the sunroof will continue to operate
until any door is open or when the Retained Accessory Power (RAP) has timed out.
For a description and operation of the RAP operation, refer to
Retained Accessory Power (RAP) Description and Operation
in Retained Accessory
Power.
Use the rocker type sunroof switch, located in the front center of the headliner,
to command the sunroof to :
Pressing the sunroof switch (rearward portion), the sunroof glass will slide
from:
| • | Vent position to the closed position. |
| • | Closed position to the open position. |
Pressing the sunroof switch (forward portion), the sunroof glass will slide
from:
| • | Open position to the closed position. |
| • | Closed position to the vent position. |
To Vent Open
To open the power sunroof to the vent position from the closed position, turn
the ignition to ON, with engine OFF. Press and hold the sunroof switch (forward portion).
This will apply the sunroof switch low reference to the sunroof switch close signal
circuit (5 volt reference) input to drop to 0 volts. As long as the
sunroof control module sees a constant input request from the sunroof switch close
signal circuit (0 volts), the control module will continue to raise the rear
of the glass upward to the full vent position. The sunroof glass will stop (soft
stop) at the full vent position based on the inputs from the limit switches. To stop
the sunroof glass in a position other than the full vent position, release the sunroof
switch when the sunroof glass reaches the desired vent position. The sunshade will
have to manually slide open.
To Close from Vent Position
To close the power sunroof from the vent position, turn the ignition ON, with
the engine OFF. Press and hold the sunroof switch (rearward portion). This will apply
the sunroof switch low reference to the sunroof switch open signal circuit (5 volt
reference) input to drop to 0 volts. As long as the sunroof control module
sees a constant input request from the sunroof switch open signal circuit (0 volts),
the module will continue to lower the rear of the glass (downward) to the closed
position. The sunroof glass will stop (soft stop) at the closed position based on
the inputs from the limit switches. The sunshade will have to be manually slid closed.
Express Open
The express open will work only with the glass in between the closed and partially
open positions. To express open the power sunroof, turn the ignition ON, with engine
OFF. Press the sunroof switch (rearward portion) once (less than 1.5 seconds). This
will apply the sunroof switch low reference to the sunroof switch signal open signal
circuit (5 volt reference) input to drop to 0 volts momentarily. The
momentary 0 volts input to the sunroof control module indicates an express
open request. The sunroof glass will lower slightly, then begin to automatically
slide (express open) between the roof and headliner, allowing the wind deflector
to raise upward. The sunroof glass will stop (soft stop) at the full open position
based on the inputs from the limit switches. As the sunroof glass expresses open
so will the sunshade. To stop the sunroof glass in a desired position other than
to the express open position:
| • | As the sunroof is expressing open, press the sunroof switch again (in
either direction) to stop the movement. |
| • | Instead of momentarily pressing the sunroof switch to express open, maintain
pressing (more than 1.5 seconds) the sunroof switch (rearward portion). When the
sunroof glass reaches the desired position, then release the switch. |
To Close from Open Position
To close the power sunroof from the open position is the same as to opening
the sunroof glass to the vent position. Turn the ignition ON, with the engine OFF.
Press and hold the sunroof switch (forward portion). This will apply the sunroof
switch low reference to the sunroof switch close signal circuit (5 volt reference)
input to drop to 0 volts. As long as the sunroof control module sees a constant
input request from the sunroof switch close signal circuit (0 volts), the
module will continue to slide the sunroof glass to the closed position. The sunroof
glass will stop (soft stop) at the closed position based on the inputs from the limit
switches. The sunshade will have to be manually slide closed.
Sunroof Motor
The sunroof has a bi-directional motor. When the motor is not operating both
circuits are grounded. When the motor drives the sunroof glass in the direction from
the vent to closed or closed to open position, the following occurs:
| • | Voltage is supplied to the sunroof motor/actuator feed open circuit. |
| • | Ground is maintained to the sunroof motor/actuator feed close circuit. |
When the motor drives the sunroof in the direction from the open to closed or
closed to vent position, the following occurs:
| • | Voltage is supplied to the sunroof motor/actuator feed close circuit. |
| • | Ground is maintained to the sunroof motor/actuator feed open circuit. |
The sunroof module is equipped with a timer circuit which stops the operation
of the sunroof motor after 8 seconds.
Limit Switches
The limit switches are part of the Sunroof Opening Position Switch (SOPS) that
tracks the position of the glass through the limit switches and understands the limits
(soft stops) of travel to the:
The sunroof control module monitors the limit switches SOPS. As a limit switch
closes, the sunroof limit switch circuit 5 volt reference will be shorted
to the sunroof limit switch low reference circuit, pulling the reference voltage
to 0 volts. The sunroof control module understands the position of the sunroof
glass based on the multiple input combinations through the limit switch inputs, which
brings the sunroof glass to a soft stop when it reaches the full vent or full open
positions and when it has reached the closed position.
