Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of the faults should be considered when the diagnostic tool is switched on after
the + after ignition feed is switched on (with no system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as defective,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because
the data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult
the corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
Customer complaints.
A synopsis of the general procedure to follow is provided on the following page in
the form of a flow chart.

3 - Features
The CARMINAT NAVIGATION and COMMUNICATION system is involved in the following functions:
–Receiver.
–CD multi-changer.
–Satellite guidance navigation.
–Hands-free telephone integrated control.
–Display.
–Clock.
A - Receiver
This function is used for listening to AM and FM radio. The receiver automatically selects the best frequency for a
station using the AF function. It receives traffic information via the Traffic Message Channel (TMC) to make best use
of the Carminat Navigation and Communication system.
B - CD multi-changer
The CD multi-changer located on the dashboard can hold up to 6 CDs. This can play audio CDs, CD-Rs which have
been copied by the customer and CDs on which MP3 files are stored. The number of CDs in the changer can be
viewed via PR005 Number of CDs in the changer.
C - Navigation
This function guides the driver by displaying maps and issuing voice messages. Addresses for guidance can be
entered via the central control or as voice commands.
D - Hands-free telephone integrated control
This function enables the driver to use a mobile phone hands-free using the microphone located next to the driver's
sun visor and the vehicle speakers. The Carminat Navigation and Communication system lets you use the
phonebook, receive and make calls and receive SMS text messages. The phone can be connected to the vehicle
with Bluetooth (wireless).
E - Display
The display is used to display information such as navigation maps, radio, CD title, time, temperature and
information from the mobile phone
F - Clock
This function displays the time on the video display.

●Receiver: the receiver transmits audio signals via the speakers inside the vehicle.
●Display: displays different multimedia information such as the station tuned in, the time, or information related to
CDs or satellite navigation.
●Steering column switch: different multimedia functions can be accessed via controls on the steering wheel.
●Speakers and tweeter speakers: produce sound from the multimedia system inside the vehicle.
●CD multi-changer: loads CDs and sends audio signals to the receiver.
●AM/FM aerial: picks up waves from various transmitters.
●GPS aerial: receives various signals emitted by satellites.
●Navigation central control: different multimedia functions can be intuitively accessed via a multimedia keypad.
●Microphone: enables a phone to be used in hands-free mode via a Bluetooth connection.
●Navigation computer: manages the various multimedia system functions according to the requests of the user.
●DVD cartographic map: loads maps onto the navigation computer.
●AM/FM aerial amplifier: improves the reception of AM/FM signals.

NOTESConditions for applying fault finding procedures to stored faults:
Apply this fault finding procedure if the fault reappears as present or stored after it has
been cleared, the ignition turned off and on again and the navigation system started.
Use the Wiring Diagrams Technical Note, Scenic II.
1.DEF
NOTESNone
Check the condition and connection of the display connector (component code 1127) and of the navigation
computer 32-track connector (component code 662) (broken, oxidised, bent tabs).
Manipulate the wiring harness at the connectors to produce a change in fault status (present → stored).
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
With ignition on, check for + 12 V on the BCP3 connection of the component 1127 connector.
Check that the earth on the MAN connection of component 1127 is perfect.
If any connection is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring; otherwise, replace the wiring.
If the fault is still present, replace component 1127.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults using command RZ001 Fault memory.
Deal with any other faults.
