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 manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu Schéma (CD-ROM), paper.
Type of diagnostic tools
–CLIP
Special tooling required
3. REMINDERS
Procedure
To run fault finding on the vehicle computers, switch on the ignition. Proceed as follows:
–turn the ignition key to APC,
–connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–turn the ignition key to OFF,
–verify that the forced + after ignition feed has been switched off by checking that the computer warning lights on
the control panel have gone out. Vehicle(s): New Twingo

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 the + 12 V feed or with another wire.
If a fault is detected, repair or replace the wiring harness.

INSTRUMENT PANEL
Fault finding - Function
The instrument panel provides the following functions:
–Illumination of the direction indicator light:
The dual direction indicator light comes on if the driver has manipulated the indicator switch to inform of a change in
direction.
–Illumination of the light indicator lights:
–The side light indicator light comes on when the side lights are switched on.
–The dipped headlights indicator light comes on when the dipped headlights are switched on.
–The main beam headlights indicator light comes on when the main beam headlights are switched on.
–The front fog light indicator light comes on when the front fog lights are switched on.
–The rear fog light indicator light comes on when the rear fog lights are switched on.
–Side lights reminder buzzer:
–The “side lights reminder” buzzer sounds when the driver's or passenger's door is opened, with the APC off and
the side lights on, to warn the driver that the lights are still on.
–Operation of the “automatic headlighting activation - deactivation or automatic locking when driving”
buzzer:
–The “connection” warning sound is emitted by the instrument panel buzzer when the “automatic headlighting” or
“automatic locking when driving” functions are activated.
–The “disconnection” warning sound is emitted by the instrument panel buzzer when the “automatic headlighting” or
“automatic locking when driving” functions are deactivated.
–“Overspeed function - Arabia” buzzer operation:
Warns the driver that the speed threshold has been exceeded, depending on the country and the equipment.
