Check the insulation and continuity of
connection 47F between components 1094 and
1579; be careful of the intermediate connectors
R339 and R301.
Is the connection OK?
Carry out fault finding on the ABS (see 38 C,
Anti-lock braking system, Introduction).
If there is a repair method (See Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring, otherwise replace it.
After the wiring has been repaired, carry out
an initialisation (see Electric sunroof:
Initialisation).
Disconnect the other components attached to
this connection before working on the wiring
(e.g.: radio, electronic power-assisted
steering).

When using the oscilloscope (CLIP)
1 - Set the oscilloscope with a time base of 5 ms/div and a calibration of 5 V/div (as shown in the illustration).
2 - Convert the signal into time in seconds.
Example: T = 12 ms = 0.012 s.
3 - Convert this time into frequency.
E.g. F: 1/T = 1/0.012 = 83.333Hz
Oscilloscope or multimeter in frequency meter mode
To convert frequency to km/h, multiply the frequency by 18 and divide by 25.
E.g.: 83.333 (Hz) X 18/25 = 60 (km/h)
The frequency of the measured signal gives the approximate speed on the instrument panel.
ALP 3 Procedure
NOTESUse Wiring Diagram Technical Note, New Twingo.
Check that the sunroof works properly when the vehicle is stationary.
Use the diagnostic tool and/or a multimeter.
IMPORTANT
In order for the ABS computer to send a signal to connection 47F, run command AC195 using the CLIP tool. This
command generates a speed signal on the wire connection (approx. 100 Hz ) addressed to all the electrical
consumers of this information (radio, roof, etc.). This command (AC195) has no visible effect on the instrument
panel speedometer. For vehicles without ABS, carry out a road test.

Electric sunroof - Fault finding chart87D
ALP 4The sunroof is difficult to close or the anti-pinch is triggered
without any apparent obstacles
NOTESCarry out the various checks with the battery charged and + after ignition feed switched
on.
Initialise the sunroof (see Electric sunroof:
Initialisation).
Is the fault still present?
YES
Open the sunroof (if this is not possible see:
defect and safe mode) Remove the sunroof
motor (see MR 411 mechanical, 87D Electric
windows-sunroof, Sunroof opening motor:
Removal - Refitting).
Slide the moving panel of the sunroof manually.
Does the moving panel slide without a point
of resistance?
YES
Check that there is no point of resistance (on the
gear pinion) to affect the running of the electric
sunroof motor).
Does the motor run without a point of
resistance?
YES
Initialise the sunroof (see Electric sunroof:
Initialisation).
If the fault is still present, replace the sunroof
computer (see MR 411 mechanical systems,
87D, Electric windows-sunroof, Electric
sunroof computer: Removal - Refitting).
NOFault solved
NO
Replace the sunroof motor (see MR 411
mechanical systems, 87D, Electric
windows-sunroof, Electric sunroof motor:
Removal - Refitting).
NO

Remove the sunroof mobile panel (see MR 412
Bodywork, 52A, Non-side opening element
mechanisms, Sunroof mobile panel: Removal
- Refitting). Visually check that no foreign
bodies (sand, leaves, etc.) are present in the
rails.
Are any foreign bodies present?
YES
Is the anti-pinch triggered when the sunroof
reaches the deflector?
YES
Remove the sunroof deflector (see MR 412
bodywork, 52A Non side opening elements
mechanism, sunroof deflector: Removal -
Refitting). Initialise the sunroof (see Electric
sunroof: Initialisation).
Is the anti-pinch still triggered?
YES
Replace the sunroof motor (see MR 411
mechanical systems, 87D, Electric windows -
sunroof, Electric sunroof motor: Removal -
Refitting).
NO
NO YESClean the mechanism and the rails. Refit the
sunroof mobile panel (see MR 412
Bodywork, 52A, Non-side opening
element mechanisms, Sunroof mobile
panel: Removal - Refitting).
Initialise the sunroof (see Electric sunroof:
Initialisation).
Replace the sunroof (see MR 412
Bodywork, Non-side opening element
mechanisms, Sunroof: Removal -
Refitting).
Replace the sunroof deflector (see MR 412
bodywork, 52A Non-side opening
elements mechanism, sunroof deflector:
Removal - Refitting). Initialise the sunroof
(see Electric sunroof: Initialisation).
