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
Special tooling required
3. REMINDERS
Procedure
To save energy, the vehicle's UCH interrupts the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the following
procedure:
– press the unlocking button on the card,
– insert the card in the reader,
– press the start button (interrupting the timed + after ignition feed mode),
– press the start button for more than 5 seconds, without conditions for starting being met, until the immobiliser
warning light flashes rapidly (4 Hz).
This forced + after ignition feed mode is active for 1 hour.
Pressing the start button or removing the card from the card reader interrupts the forced + after ignition feed, but
does not interrupt the time period for the forced + after ignition feed. Until one hour has elapsed, activating the +
after ignition feed will restart forced + after ignition feed for the remaining time. Vehicle(s): MEGANE II phase 2, SCENIC II
