ALP 6 Radio reception faults
Poor radio reception.
Does the radio "scan"the stations in FM mode?
NO
Does the sound cut out for < than 1 second from
time to time in FM mode?
Does the radio crackle?
NO YES
The vehicle is in an area of poor reception.
YESFault external to the radio (transmitter
synchronisation).
YESThe vehicle is in an area of poor reception.
The radio takes longer to find an adequate
transmitter.
Disable AF in Expert mode.
With the vehicle outside and in an area with
good reception, test the reception level in the
radio's fault finding menu.

CONTINUED 1
Is the reception level good?
YES
Check whether the poor reception is localised or
permanent and on all stations.
Is the fault permanent?
YES
Check the continuity and insulation of the wiring
between the radio and the aerial amplifier. Carry
out the tests on the aerial.
YES
Is the test OK?
YES
Replace the radio.NOWithout moving the vehicle, compare the
level with that of a Long Wave station.
Is the level higher?
NO
Check the vehicle
aerial.
NOThe vehicle is in an area of
poor FM reception.
NOIf there is a repair procedure (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring, otherwise replace it.

*SDVC: Speed-dependent volume control.
ALP 7 The volume does not increase with the vehicle speed.
The SDVC* function does not work.
Check the radio configuration (Expert mode).
Set the “SPEED” curve to 5 and run a test when
driving at a speed greater than 48 mph (80 km/h).
Does the volume vary?
YES
The fault has been rectified.
Reset the control to: CURVE 2.
NOCheck the signal on connection 47F
(See Wiring Diagrams Technical Note New
Twingo, code 261) with a multimeter in the
frequency meter position or with an
oscilloscope.
The frequency should change with the speed.
Does the signal frequency change with the
speed?
NO YES
Replace the radio.
The fault is linked to the speed signal
(see 38C, Anti-lock braking system,
conformity check).

ALP 8 Lighting does not change when the vehicle lights are switched on
Lighting does not change when the vehicle lights
are switched on.
Switch on the lights and check for + 12 V on the
following connections:
–LPD between components 1016 and 261,
–LPD between components 1016 and 653.
Is there + 12 V?NO
YES
Replace the radio.
The fault is not associated with the audio
equipment. Check the continuity and
insulation of the LPD connection with a
multimeter (see Wiring Diagrams Technical
Note for New Twingo, code 261).
YESIs the test OK?
NO
If there is a repair procedure (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring, otherwise replace it.
