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 + 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

Fault finding - Interpretation of statuses
ET002
SIDE LIGHTS SWITCH
STATUS
DEFINITION–ACTIVE: This status indicates that the side light control is active.
–INACTIVE: This status indicates that the side light control is inactive.
NOTES–Ignition on.
–Side lights on.
If the status of the side light control remains at status INACTIVE, apply the following fault finding procedure.
Check fuse F43 (10A) of the passenger compartment fuse box, component code 1016.
Check that the connection and condition of the rev counter connector are correct (see Wiring Diagram Technical
Note, Twingo II, Component code 995).
If there is a repair method (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair)
repair the connector, otherwise replace the wiring.
Check the + 12 V feed on connection LPG of component 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Check the continuity and insulation of:
Connection LPG between the passenger compartment fuse box, component code 1016 and the rev
counter, component code 995.
Connection MAM of the rev counter, component code 995.
Connection MAN of the rev counter, component code 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault is still present, contact the techline.
