PINPOINT TEST C: THE ROOF OPENING PANEL HAS EXCESSIVE WIND NOISE
|
Normal Operation and Fault Conditions
During normal operation the sunroof seals against
the roof opening tightly and evenly preventing wind noise. Any failure
to seal will cause wind noise.
Possible Sources
- Front trim seal
- Primary seal
- Acoustic seal
- Air deflector
Visual Inspection and Pre-checks
- Roof opening panel seals
- Air deflector
|
| C1 VERIFY ROOF OPENING PANEL NOISE |
|
NOTE:
It is normal to have some amount of wind noise when
the roof opening panel is in the OPEN position. To determine if the wind
noise is excessive, road test the vehicle at approximately 100 km/h (62
mph) with the roof opening panel closed, a single rear door window open
and all remaining door windows closed while observing the level of wind
noise. If the level of wind noise observed with the roof opening panel
open (with all door windows closed) is greater than the wind noise
observed with a single rear door window open, the wind noise is
excessive.
-
Road test the vehicle with the roof opening panel in the CLOSED, VENT and OPEN positions.
Is the wind noise present only in the OPEN position?
|
| C2 CHECK THE ROOF OPENING PANEL GLASS SEALS |
|
NOTE:

PINPOINT TEST D: THE ROOF OPENING PANEL LEAKS
|
Normal Operation and Fault Conditions
When the roof opening panel glass is completely
closed, it is flush with the roof panel. The roof opening panel primary
seal provides a seal against adverse weather conditions such as rain and
wind, preventing them from entering the passenger compartment. A
damaged, deformed or incorrectly installed seal is unable to seal the
glass efficiently. The roof opening panel frame assembly provides a
route for water to drain away from the opening panel into the body panel
drains. Obstructed openings in those drains will allow water to collect
and possibly leak into the passenger compartment.

TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB
instructions. If no Technical Service Bulletins (TSBs) address this
concern, INSTALL a new roof opening panel motor and shield motor.
REFER to: Roof Opening Panel Motor (501-17 Roof Opening Panel, Removal and Installation).
TEST the system for normal operation. If the concern still exists,
INSTALL a new roof opening panel control switch. REFER to: Roof Opening
Panel Control Switch (501-17 Roof Opening Panel, Removal and
Installation).
|
| No |
The system is operating correctly at this time. The
concern may have been caused by a loose or corroded connector.

PINPOINT TEST H: THE ONE-TOUCH OPEN/CLOSE IS INOPERATIVE
Refer to Wiring Diagrams Cell 101 for schematic and connector information.
Normal Operation and Fault Conditions
All of the roof opening panel switches are single
position switches that can achieve one touch operation in either
direction by pressing the switch for less than 1 second. For manual
operation, simply press and hold the switch until the roof opening panel
or shield is in the desired position and release the switch. When the
front roof opening panel is in the fully closed or between fully closed
and full vent position the vent switch operates in either manual or one
touch operation similar to the roof opening panel and shield switches.
If the shield is not open at lease to the front of the rear fixed glass
(comfort stop) when the vent or roof opening panel glass open switch is
pressed then the shield will first open to the comfort stop position
before the roof opening panel glass will move. The roof opening panel
glass and the shield will not move at the same time. One touch operation
of either the roof opening panel or the shield can be cancelled anytime
by pressing any roof opening panel switches during operation. When the
sunroof is open and the sunroof close switch is pressed for one touch
operation, a signal is sent to the sunroof motor through on the sunroof
close circuit causing the sunroof to perform a one-touch close operation
(closes to approximately 8 in. (200mm) from the closed position only).
The sunroof open one touch operation is the same as sunroof close,
except if the shield is closed when the sunroof motor is commanded to
perform a one-touch open operation the motors will communicate and the
shield motor will perform a one-touch open operation, then the sunroof
motor will perform the one-touch open operation requested. The shield
one touch operation is the same as the sunroof except if the sunroof is
open, the shield will only move to the comfort stop position. The
sunroof will not open as a result of a shield one touch close operation.
For more information on the operation. REFER to: Roof Opening Panel -
System Operation and Component Description (501-17 Roof Opening Panel,
Description and Operation).
