Fault finding - Introduction86A
Procedure (continued)
Espace IV ph2:
In order to save energy, the Espace IV Phase 2 UCH cuts off the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed on for 1 hour by applying the
following procedure:
–Press the card unlocking button.
–Insert the card into the card reader.
–Press the Start button (interrupting the timed + after ignition feed mode).
–Press and hold the start button for over 5 seconds until the engine immobiliser warning light starts to
flash rapidly (4 Hz).
This "forced + after ignition feed" mode remains active for 1 hour.
Pressing the start button or removing the card from the reader cuts off the forced + after ignition feed but does not cut
off the timed forced + after ignition feed mode. As long as one hour has not passed, the + after ignition feed function
restarts the forced + after ignition feed for the remaining time.
Trafic II ph2 and Kangoo 2:
To run fault finding on the vehicle computers, switch on the forced + after ignition feed.
Faults
Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they
are still present but cannot be diagnosed in the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used following
the + after ignition supply being switched on (without operating the system components).
For a present fault, apply the method described in the section on Interpretation of faults.
For a stored fault, note the faults displayed and apply the notes section.
If the fault is confirmed when the instructions in the Notes section 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).

Fault finding - Introduction86A
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 repair.
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 summary of the overall procedure to follow is provided on the following page in the form
of a flow chart.

Fault finding - Role of components
Role of main components
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Steering column control: allows the various system functions to be used via the steering wheel control.
–Speakers and tweeters: relay the sound from the multimedia system into the vehicle.
–CD changer: enables compact discs to be loaded and music to be relayed to the receiver.
–AM/FM aerial: receives radio signals from various transmitters.
–GPS aerial: receives various data transmitted by satellites.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.
–Cartographic map DVD: loads maps into the navigation computer.
–AM/FM aerial amplifier: improves the reception of AM/FM signals.
–Multimedia network interface unit: enables information to be exchanged between the "vehicle" and "multimedia"
multiplex networks. This computer is involved in activating the multimedia system.

Fault finding - Function
General operation
The multimedia system is involved in the following functions:
–Radio reception (AM, FM).
–Playing CDs/MP3 CDs/navigation map.
–Guidance and navigation system with colour screen.
–Bluetooth hands-free phone.
The use of this multimedia system allows the customer:
–To select radio stations by using the preselections, the list or manual selection.
–To have an automatically-updated radio list.
–To listen to CDs or MP3 CDs.
–To control the radio using the steering column switch (satellite).
–To change various acoustic parameters (bass, treble, fader, etc.).
–To navigate on a colour screen (visual and audio guidance): for this function the system uses GPS, the
vehicle speed wire information and an internal gyroscope.
–To receive traffic information via RDS-TMC and to display it on the navigation map. Possibility of re-
routing according to traffic information.
–To display the time and temperature on the screen.
–To use the hands-free phone function (sound relayed to the radio speakers) with a Bluetooth phone (HFP
profile).
–To be protected by an immobiliser code.

Fault finding - Configurations and programming
SETTINGS
VP001: Write VIN
This command permits manual entry of the vehicle's VIN into the computer. Use this command each time
the computer is replaced. The VIN number is inscribed on the manufacturer's plate.
Procedure for writing the VIN
–Establish dialogue with the navigation computer.
–Select the Repair mode menu.
–Select the Other parameters menu.
–Select line VP001 Write VIN.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait for the end of power latch.
–Reread the VIN in the Identification menu for confirmation (ID014 VIN code).
VP003: "Enter After-Sales operation date"
This command is used to enter the date of the last After-Sales operation on the LPN* radio navigation
system.
VP005: Computer calibration and commissioning
This command is used to configure the LPN* radio navigation computer following its replacement. When
the command is complete, switch off the ignition, wait 2 minutes and switch on the ignition again. Check
that the configuration has registered correctly by re-reading the following configuration readings:
–LC008 "Vehicle configuration",
–LC012 "CD changer",
–LC015 "Vehicle type",
–LC016 "Distance units".
The radio is in factory mode after configuration (FM 87.5 MHz in scrambled mode for 2 minutes).
CONFIGURATIONS
CF013: CD changer
This command is used to indicate whether or not a CD changer is present under the front left-hand seat.
CF018: Distance units
This command is used to change the measurement unit for the distances displayed on the radio navigation
screen.
PROGRAMMING
There is no programming on the navigation system.
Important: After activating the system, the delay before establishing dialogue can last 20 seconds.
*LPN: Low Price NavigationNote:
Use the following commands if the configurations are incorrect after having used VP005 Computer calibration
and commissioning.
