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).
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:
–Renault card in the card reader (keyless vehicle scenario 1, entry level, not hands-free and scenario 2, top of the
range, hands-free),
–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 + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–Press the start button twice briefly (less than 3 seconds),
–Check that the + after ignition feed has been cut off by checking that the computer warning lights on the instrument
panel have gone out. Vehicle(s): Scénic II, Laguna II ph1, Velsatis

4. DEFECT MODE
If a system component is defective, no indicator lights up on the instrument panel.
The system then switches to defect mode.
If the computer detects a system fault, it sets the adjustment motors to the low or initial position.
If the computer detects a fault, there is no longer any initialisation when the lights are turned on.
