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.

When Monitored:
With the ignition on.
Set Condition:
The Totally Integrated Power Module (TIPM) will set this DTC if it detects an overcurrent condition on the
(F942) Fused Ignition Switch Output (Run-Start) circuit for more than 500ms when blower motor operation is
