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:Vehicle(s): Espace IV phase 2, Scénic II phase 2,
Trafic II phase 2, Kangoo 2
Function concerned: Multimedia
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).
Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.

Procedure (continued)
Espace IV ph2: To save energy, the UCH on the Espace IV Phase 2 cuts out the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed on for 1 hour by applying the following
procedure:
–Press the card unlocking button.
–Insert the card into the reader.
–Press the Start button (interrupting the timed + after ignition feed mode).
–Press and hold the Start button for over 5 seconds until the engine immobiliser warning light starts to flash
rapidly (4 Hz).
This forced + after ignition feed mode remains on for 1 hour.
Pressing the Start button or removing the card from the reader cuts off the forced + after ignition feed but does not cut off
the timed forced + after ignition feed mode. As long as one hour has not elapsed the + after ignition feed function restarts
the forced + after ignition feed for the remaining time.
Trafic II ph2 and Kangoo 2:
To run fault finding on the vehicle computers, switch on the forced + after ignition feed.
Faults
Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they are still
present but cannot be diagnosed in the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used following the +
after ignition supply being switched on (without operating the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the data is
inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repair.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the corresponding
fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints.
A summary of the overall procedure to follow is provided on the following page in the form
of a flow chart

4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating 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.
Tactile 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 to another wire.
If a fault is detected, repair or replace the wiring harness.
