Fault finding - Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedure (this manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma (CD-ROM), paper.
Type of diagnostic tools
–CLIP + multiplex line sensor
Special tooling required
3. REMINDERS
Procedure
Scénic II ph2:
To run fault finding on the vehicle computers, switch on the forced + after ignition feed.
Proceed as follows:
*LPN: Low Price NavigationVehicle(s): Espace IV phase 2, Scénic II phase 2,
Trafic II phase 2, Kangoo 2
Function concerned: Radio, satellite navigationName of computer: LPN* radio navigation
VDIAG NO: C4
Special tooling required
Multimeter
Elé. 1681 Universal bornier
Switch on the forced + after ignition feed:
–with the vehicle card in the card reader,
–press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
–connect the diagnostic tool and perform the required operations.
Switching off the forced + after ignition feed:
Press the Start button twice briefly (less than 3 seconds).
See that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument
panel have gone out.

Fault finding - Conformity check
MAIN COMPUTER STATUSES AND PARAMETERS
*degrees/second
NOTESOnly check the conformity after a complete check with the diagnostic tool.
The values shown in this conformity check are given as a guide.
Application conditions: engine stopped, ignition on.
FunctionParameter, Status
checked or ActionDisplay and notes Fault finding
Vehicle speedPR010:Vehicle speedUnit: km/hIn the event of a fault, consult
the interpretation of parameter
PR010 Vehicle speed.
Satellite receptionPR008:Number of
satellites receivedIn an open area, the number of
satellites received should be
greater than 3 for the system to
operate correctly.In the event of a fault, consult
the interpretation of parameter
PR008 Number of satellites
received.
Angular position
sensorPR009:Angular positionUnit: ˚/s*
This parameter determines the
angular speed during cornering.In the event of a fault, consult
the interpretation of parameter
PR009 Angular position.

ALP 1 No dialogue with the LPN* computer
NOTESStart the engine.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2,
Trafic II ph2 or Kangoo 2.
Important: After activating the system, the delay before establishing dialogue can last
20 seconds.
Try the diagnostic tool on another vehicle.
Is dialogue possible with a computer?
YES NO
On the defective vehicle.
Check the voltage of the battery.
Check the condition and connection of the battery
connections.
Check the condition of the fuses.
Check:
–the connection between the diagnostic tool and
the diagnostic sensor (wiring in good condition),
–the connection between the diagnostic sensor
and the diagnostic socket (wiring in good
condition).
AFTER REPAIRCarry out a complete check with the diagnostic tool.
