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.

STOREDCOMPUTER
1.DEF: Internal electronic fault
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
–the multimedia system has been switched on using the on/off button,
–a road test in an area with no satellite coverage (tunnels, etc.).
Special note:
The vehicle position is incorrect.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Check that the PR010 Vehicle speed wire signal and the multiplex information on the instrument panel
correspond by carrying out a road test.
If both signals are identical but appear incorrect compared to the actual situation, run fault finding on the speed,
ABS or ABS/ESP computer depending on the equipment level (see 38G, Vehicle speed computer or 38C, Anti-
lock braking system).
Look for any damage to the wiring harness, and check the condition and connection of the connectors for
components 261 and 1094, 118 or 953 (depending on the equipment level).
Manipulate the wiring harness in order to observe a change in the fault status (present → stored).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Check the continuity, insulation and the absence of interference resistance on the following connection:
–Connection code 47F between components 261 and 1094, 118 or 953 depending on the equipment level.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
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.
