ALP 2The radio does not work (no sound) when the
“ON” button is pressed
Press the radio's “ON” button.
YES
Is the display working? (backlighting)
NO
Check the radio's fuse F48 (15A) (see Wiring
Diagrams Technical Note for New Twingo,
code 1016).
Is the fuse sound?
YES
Check the continuity of connections BCP4 and
MAO (see Wiring Diagrams Technical Note
for New Twingo, code 261).
Is the wiring harness sound?
YES
Replace the radio.
YES
NOCheck the insulation to earth of connection
BCP4 between components 1016 and 261. If
the insulation is correct, replace the fuse, or if
it is faulty and if there is a repair procedure
(see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
NOIf there is a repair procedure (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring, otherwise replace it.

ALP 2
CONTINUED 1
Is the volume set to “0” or muted?
NO
Is the "Fader"* set fully to the
rear speaker position?
NO
Speaker connector disconnected. Check that the
speaker tracks (34A to 34H) have no short circuit
or are not earthed using a multimeter (see
Wiring Diagrams Technical Note for New
Twingo, codes 189 to 190, 365 to 366 and
1597 to 1598).YESCheck insulation to earth of connection 107D
(for vehicles fitted with a hands-free kit).
If the insulation is not correct and if there is a
repair procedure (see Technical
Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the
wiring, otherwise replace it.

ALP 3The radio does not switch on automatically or switches off
after 20 minutes
Check that the system is operating correctly.
–Switch to + after ignition position.
–Switch on the radio.
–Switch off the + after ignition feed; the radio
should switch off.
–Switch on + after ignition feed again; the
radio should switch on.
Has the fault disappeared?
NO
Check the + accessories feed with a
multimeter.
Is there + 12 V on connection SP2 of the radio
(component 261)?
YES
Replace the radio.
YESEnd.
NOCheck supply fuse F29 (15A) (see Wiring

ALP 4The radio is switched on, but the display and control satellite do
not operate
NOTESFor radio versions with remote display.
The radio operates but the display does not
light up.
Check the functions of the display that are not
connected to the radio by switching on the “+
side lights feed” (screen backlighting and
exterior temperature).
Does the backlighting or exterior temperature
display work?
YES
Check the continuity and insulation of the wiring
between the radio and the display using a
multimeter (see Wiring Diagrams Technical
Note for New Twingo, code 261).

does not.
Does the remote display operate?
YES
Check that the satellite is correctly connected to
the display (see Wiring Diagrams Technical
Note for New Twingo, code 325).
Are the satellite controls connected correctly?
YES

*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).
