Role of components
Role of main components:
●Radio: the radio transmits audio signals into the vehicle via speakers.
●Aerial: the aerial is used to receive radio waves from different stations.
●CD changer: used for loading CDs and playing music via the radio.
●Display: the display shows radio information such as the name/frequency of the radio station being listened to,
the sound level, as well as different audio settings. If a carphone is fitted to the vehicle, information from this will
appear on the display.
●Speakers: produce sound from the radio. There are 6 enclosures (2 at the front, 2 at the rear and 2 front
speakers).
●Steering wheel control: various radio functions can be controlled from the steering wheel.

RADIO
General Information
For repairs or fault finding, the receiver is fitted with a test menu (see radio self-test procedure).
The radio will operate for approximately 20 minutes without the ignition being switched to the accessories position.
The radio bleeps then switches off.
Notes:
●All radios are designed to control a CD changer.
●There is a special procedure for replacing the CD changer located in the dashboard front panel.
RADIO FUNCTION
The tuner has three selection modes displayed on the screen and accessible from the radio front panel:
–manual mode (MANU),
–preset mode (PRESET),
–alphabetical mode (LIST).
CD FUNCTION
The CD player can play conventional discs and any audio tracks on a CD-ROM.
CDs can be played in order or tracks can be chosen at random.
If a CD changer is being used, random play is possible on only one of the possible 6 compact discs.
THERMAL PROTECTION
If the radio temperature is too high for it to function properly, the volume is automatically reduced (without changing
the volume shown in the display).
Should one of the speaker tracks short circuit, the supply to the amplifier will be cut off.
VOLUME CONTROL
The volume can be increased according to the vehicle speed. To activate the function, select the desired volume
adjustment curve in expert mode (press and hold the source button until you hear a bleep): SPEED 5 for maximum
increase, 0 to switch off the increase function.

Self-test procedure
The self-test procedure mode of the previous generation radios (PN0-6) allows certain main functions to be tested:
●by pressing buttons 2 and 4 at the same time, the speakers can be tested. They are supplied one by one; the
display enables the connections and signals from each speaker to be checked,
●by pressing buttons 1 and 6 at the same time, the reception level can be tested (after frequency is displayed),
–9 or letter: good reception,
–
–less than 3: poor reception,
–if 2: total loss of stereo.
The self-test procedure mode of the new generation radios (NR4/5) enables certain main functions to be tested
using the combination of buttons 1, 6 and i. The messages will be displayed in the following way:
●Radio pre-code (one letter/three digits) displayed to avoid the need to remove the radio,
●speaker test with two beeps (bass - treble) from the speakers, with the tested speakers shown on the display
(front left-hand H01, front right-hand H02, rear right-hand H03, rear left-hand H04),
●displays the frequencies and levels of the tuner sensors,
●software version displayed, displays fault finding for the connected aerial if the aerial is supplied by a coaxial
cable; in this case, the display shows H15 with X = 0, 1 or 2 depending on the aerial status (0: open circuit,
1: short circuit to earth, 2: power consumption),
●audio test loudness OFF (H08), cuts any loudness for an audio test.
Note:
The source usage times in 1/6ths of an hour is also displayed (Tuner (H09)/CD (H10)/cassette (H11)/CD changer
(H12)/auxiliary (13)/MP (H14)/Total (H15)).

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.
