The power sunroof system allows the sunroof to be opened, closed or placed in the vent position electrically by
actuating a switch in the overhead console. The sunroof system receives battery feed through a fuse in the Power
Distribution Center (PDC). The sunroof will operate normally with the keyin any position while the Accessory Delay
system is active.
The sunroof glass panel tilts upward at the rear for ventilation and slidesrearward under the roof when open. The
panel seals flush with the roof in the closed position to eliminate wind noise. The sunroof includes a manual-sliding
sunshade to cover the deep-tinted glass panel.
In addition to the standard power sunroof operation, this vehicle offers several additional features. There is an
express (one-touch) opening and closing feature as well as Excessive Force Limitation (EFL). The EFL function
detects obstacles trapped between the glass and the vehicle roof during a closing motion. Upon sensing an obstacle
the EFL function will reverse direction of the glass to allow removal of theobstacle.
The main components of thepower sunroof system are:
The motor/module assembly
The power sunroof glass and frame assembly
The power sunroof switch
The manual-sliding sunshade
OPERATION
This vehicle has a vent, tilt and slide power sunroof system with express (one-touch) open and closing feature. The
sunroof system receives constant battery feed through a fuse in the Power Distribution Center (PDC). The sunroof
will operate normally with the key in any position while the Accessory Delay system is active. If the sunroof is mov-
ing when the key is turned to the START position (crank engine), all motionsstop until the key is released, then the
previously requested sunroof motion will resume. The sunroof will also complete a requested motion if the Acces-
sory Delay system goes inactivewhile the motion is in progress.
A combination push-button and rocker switch module mounted in the overhead console controls sunroof operation.
The sunroof switch is a rocker design with a push button in the center of the two halves of the rocker. Pressing the
rocker towards the front of the car commands the sunroof closed. Pressing the rocker towards the rear of the car
commands the sunroof open. Pressing the center push button commands the sunroof up into the vent position
(Rear of sunroof glass raises above the vehicle roof with glass still covering the sunroof opening). All switch com-
mands operate with the glass startingin any position. (Refer to 8 - ELECTRICAL/POWER TOP/SWITCH - OPER-
ATION) for additional information.
An electronic control system, integralto the motor/module assembly, provides the express open and close functions.
Pressing the
openorcloseend of the rocker switch moves the sunroof glass panel to the full open or fullclosed
position, respectively. During express closing, anytime an obstacle is detected in the way of the glass, the motor will
stop and reverse travel to avoid pinching an occupant’s finger, ice in the track, etc. This function is called Excessive
Force Limitation (EFL). There are two methods of overriding the EFL function.
1. When three EFL events occur without the glass being allowed to fully close, the next close attempt will only
move while the close switch is continuously actuated. This allows the sunrooftobeforcedclosedifmultipleclose
attempts fail.
2. If the sunroof close switch is continuously actuated during an EFL event, through the reversal, and during a two
second wait time, then continuing to hold the close switch will cause the roof to move towards close with the EFL
protection disabled. This allows the sunroof to be forced closed if it is known that a reversal will occur.
While in EFL override, the closing motion will cease if the sunroof switch is released at any time.

The motor/module is programmed to learn the speed required to drive the panel based on position and recalibrates
itself as needed. If the sunroof becomes uncalibrated, it will only respond to the vent switch. If the vent switch is
pressed, the glass will move toward vent; if the switch is released, all motion stops. In the event that the sunroof
system becomes uncalibrated performthe sunroof position calibration procedure, (Refer to 8 - ELECTRICAL/
POWER TOP/MOTOR - STANDARD PROCEDURE -SUNROOF POSITION CALIBRATION).
DIAGNOSIS AND TESTING
POWER TOP - SUNROOF
Any diagnosis of the power sunroof system should begin with the use of a scantool and the proper Diagnostic
Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) Data Bus is
functional, that all of the electronic modules are sending and receiving the proper messages on the CAN Data Bus,
and that the power sunroof motor is being sent the proper hard wired output by the sunroof switch.
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
Refer to the appropriate diagnostic information.
SUNROOF
Refer to SUNROOF DIAGNOSIS CHART for possible causes. Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating condition. If not, a common electrical problem may exist. Refer to
Wiring Diagrams, in this publication for circuit, splice and component descriptions. Check the condition of the circuit
protection (20 amp circuit breaker in the Junction Block). Inspect all wiring connector pins for proper engagement
and continuity. Check for battery voltage at the power sunroof controller, refer to Wiring Diagrams, for circuit infor-
mation. If battery voltage of more than 10 volts is detected at the controller, proceed with the following tests (the
controller will not operate at less than 10 volts).
Before beginning diagnosis for wind noise or water leaks, verify that the problem was not caused by releasing the
control switch before the sunroof was fully closed. The sunroof module hasa water-management system. If how-
ever, the sunroof glass is in a partial closed position, high pressure water may be forced beyond the water man-
agement system boundariesand onto the headlining.
Every time the sunroof module loses power it must be initialized. This is done by connecting power to the sunroof
and moving the sunroof toward the closed position. When initialization occurs a slight “kick” in the sunroof module
will be seen and heard. This is the indication that the sunroof module is initialized
