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 - Replacement of components
For information on removing/refitting the LPN* radio navigation computer, refer to the MR for the vehicle concerned:
–Scénic II ph2 (see MR 370, Mechanical, 83C On-board telematics system, Navigation computer: Removal -
Refitting)
–Espace IV ph2 (see MR 405, Mechanical, 83C, On-board telematics system, Radio navigation:
Removal - Refitting)
–Trafic II ph2 (see MR 408, Mechanical, 83C, On-board telematics system, Radio navigation:
Removal - Refitting)
–Kangoo 2 (see MR 417, Mechanical, 83C On-board telematics system, Radio navigation:
Removal - Refitting)
Operations to be carried out before replacing the LPN* radio navigation computer:
Note:
If the LPN* radio navigation computer and the multimedia network interface unit are replaced
simultaneously, first configure the multimedia network interface unit (see 86D, multimedia network interface
unit, Configuration and programming).
1 -Before replacing the LPN* radio navigation computer (with Techline approval), perform a fault read and a
conformity check to confirm that it is defective.
2 -Before removing, eject the CD.
3 -After obtaining Techline approval, remove the LPN* radio navigation computer with the ignition off (wait
1 minute for the system to shut down completely).
The LPN* radio navigation computers available from the Parts Department are supplied unconfigured.
Operations to be carried out after replacing the LPN* radio navigation computer:
1. Configure the computer (see Configurations and Programming).
The LPN* radio navigation computer is in factory mode following configuration (FM 87.5 MHz in scrambled mode for
2 minutes).
Clear the present or stored faults using command RZ003 Fault memory.
2. Enter the unlocking code for the LPN* radio navigation system
How to obtain the unlocking code for the LPN* radio navigation system:
–switch on + after ignition feed (see Introduction),
–if the LPN* radio navigation system does not switch on when the + after ignition feed is activated, press the ON/
OFF button on the front panel,
–connect the Clip diagnostic tool,
–note the programming key number ID007 Radio programming key shown in the Identification menu.
–When you have this programming key number, consult Renault.net to obtain the LPN* radio navigation system
unlocking code. If the fault is still present, contact Techline.
–The unlocking code is requested 2 minutes after the LPN* radio navigation system has been switched on,
–enter the code using the radio control satellite under the steering wheel.
Important: After activating the system, the delay before establishing dialogue can last 20 seconds.
*LPN: Low Price NavigationNote:
Each time an incorrect code is entered, the waiting time doubles (maximum 32 minutes).

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
–the + after ignition feed is activated,
–the multimedia system has been switched on using the on/off button.
–move all the buttons on the LPN* radio navigation front panel,
–wait for 2 minutes.
Check the conformity of the LPN* radio navigation front panel buttons by viewing the following statuses:
–ET009 CD eject button,
–ET010 "Radio preselection button 1",
–ET011 "Radio preselection button 2",
–ET012 "Radio preselection button 3",
–ET013 "Radio preselection button 4",

–ET040 "‘SET’ button",
–ET041 "‘BACK’ button",
–ET042 "Repeat button",
–ET043 "Wheel left turn",
–ET044 "Wheel right turn".
If one of the statuses is PRESSED, move the corresponding button to change the status to RELEASED.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
