CONTINUED
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.
