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 - 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.
