ALP 5 The satellite controls do not work
NOTESFor radio versions without remote display.
The radio operates but the radio control satellite
does not.
Check that the satellite is connected to the radio
(see Wiring Diagrams Technical Note for New
Twingo, code 325).
Are the satellite controls connected correctly?
YES
Measure the satellite resistance with a
multimeter (see Radio control satellite: Test).
Are the resistance values correct?
YES
Check the continuity and insulation of the
following connections:
–34AT, 34AR, 34AS, 34AQ, 34AU and 34AP
between the satellite and the radio.
Are the connections correct?
YES
Replace the radio.
NOReconnect the radio control satellite and
check the system operates correctly.
NOReplace the satellite.
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.

ALP 9 Seat belt reminder buzzer does not switch off
The radio does not cut out during a seat belt
reminder warning when driving.
Check for an earth on connection 107D
(see Wiring Diagrams Technical Note for New
Twingo, code 261), during a seat belt reminder
warning.
Is there an earth?NO
YES
Replace the radio.
The fault is not associated with the audio
equipment. Check the continuity and
insulation of connection 107D with a
multimeter (see Wiring Diagrams Technical
Note for New Twingo, code 261).
YESIs the test OK?
NO
