Is the control correct?
YES
Check the continuity and insulation of the following connections:
●Connection code 52J.
●Connection code 52H.
●Connection code 52G between components 304 and R301.
If the continuity is faulty, use the wiring diagram corresponding to the vehicle to check the conformity of
intermediate connector R339.
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
After repairing the condition of the wiring, initialise the sunroof (see MR fault finding 87D, Electric sunroof:
Initialisation).
If the continuity and insulation of the following connections are correct: Replace the sunroof motor (see 87D
Electric windows - sunroof: Removal - Refitting).
NOReplace the control (see MR Mechanical
systems, 87D Electric windows -
sunroof, Sunroof switch: Removal -
Refitting).
AFTER REPAIRCarry out a complete check using the diagnostic tool.

NOTESOnly check this customer complaint after performing a complete check with the
diagnostic tool.
For vehicles with Mégane II phase 2 bodywork, (see MR 366, Fault finding, 87D
Electric windows - Sunroof, Fault finding chart).
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Initialise the sunroof (see MR fault finding 87D Electric sunroof: Initialisation).
Has the fault been solved?
YESNO
End of fault finding.
Open the sunroof fully (if not possible, see Defect mode and
safe mode).
Remove the sunroof motor (see MR 364 Mechanical, 87D
Electric windows - Sunroof, Sunroof motor: Removal -
Refitting).
Slide the moving panel of the sunroof manually.
Does the moving panel slide without a point of
resistance?
NO YES
Replace the sunroof motor (see 87D Electric windows -
Sunroof: Removal - Refitting).
Remove the moving sunroof panel
(see MR Bodywork, 52A, Non-side opening
element mechanisms, Mobile sunroof
panel: Removal - Refitting).
Visually check that no foreign bodies
(sand, leaves, etc.) are present in the rails.
Are there any foreign bodies in the rails?
YES NO
Clean the mechanism and the rails with an air gun. Refit the sunroof mobile panel (see MR 365 Bodywork, 52A,

Manually check that all of the linkages (front and rear) slide correctly.
Lubricate the rails, linkages and mechanisms (see MR 365 Bodywork, 52A, Non-side opening element
mechanisms, Mobile sunroof panel: Removal - Refitting). Refit the moving sunroof panel. Initialise the sunroof
(see Section: Electric sunroof: Initialisation).
Is the fault still present?
YESNO
Is the anti-pinch triggered when the sunroof
reaches the deflector?
YES NO
Remove the sunroof deflector (see MR Bodywork,
52A Non-side opening element mechanisms,
Sunroof deflector: Removal - Refitting). Initialise
the sunroof (see Section: Electric sunroof:
Initialisation).
Does the anti-pinch still trigger?
YES NO
Replace the sunroof (see MR Bodywork, Non-side
opening element mechanisms, Sunroof:
Removal - Refitting).
End of fault finding.
Replace the sunroof (see MR Bodywork, Non-side
opening element mechanisms, Sunroof:
Removal - Refitting).
Replace the sunroof deflector (see MR 365
