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 procedures (this document):
–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
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
–vehicle card in reader,
–press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled,
–connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–press the Start button twice briefly (less than 3 seconds),
–check that the computer warning lights on the instrument panel have gone out to confirm that the + after ignition
feed has been cut off. Vehicle: Scenic II ph2

4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or handling the wiring harness may temporarily remove, the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

+ 12 V SIDE LIGHTS FEED
NOTESVisually check that the side lights are working. Carry out fault finding on the steering
column switches and the side lights.
Use the Wiring Diagrams Technical Note, Scenic II.
Check the condition of the 7.5 A fuse in the engine compartment connection unit (component code 1337).
Check the condition and connection of the navigation central control connectors (component code 1657) and of
the CD changer (component code 1272) (broken, bent tabs).
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the LPG connection between
components 1337, 1272 and 1657.
If the connection is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring; otherwise, replace the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

NOTESOnly check the customer complaint after performing a full check with the
diagnostic tool.
Check that the customer is using the navigation system correctly.
Use the Wiring Diagrams Technical Note, Scenic II.
Check that the display has not been deactivated.
Press the LIGHT button on the central control for 2 seconds to reactivate the display.
To check the supply to the display, switch on
the ignition, switch on the navigation system
and eject the navigation DVD.
Has the DVD been removed?
YES
Check for + 12 V on connection BCP3 and an earth
on connection MAN of the display (component
code 1127).
Are these tests correct?
YES
Check the insulation, continuity and the absence
of interference resistance of connection 34HU
between components 1127 and 1272.
–If the connection is correct, replace the display.
–If any connection is faulty and if there is a repair
method (see Technical Note 6015A, Repairing

repair), repair the wiring; otherwise, replace
the wiring.
NOCheck the condition of the supply fuse
(20A) (component code 260).
Has the fault disappeared?
YES NO
Check for + 12 V on
connection BCP3 and an
earth on connection MX of
the navigation computer
(component code 662).
NOCheck the insulation,
continuity and the absence
of interference resistance
of connections 34DB, 34DC
et 34DD between
components 662 and 1127.
YES Are these checks correct?
NO
