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 + multiplex line sensor
Special tooling required
3. REMINDERS
Procedure
In order to save energy, the LAGUNA II Phase 2 UCH cuts off the + after ignition feed after 3 minutes.
To run fault finding on a vehicle computer, it is possible to force the + after ignition feed 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 the start button for more than 5 seconds, without conditions for starting being met, until the
immobiliser warning light flashes rapidly (4Hz).
– Connect the diagnostic tool and perform the required operations.
This forced + after ignition feed mode remains active for 1 hour.
Pressing the Start button or removing the card from the card reader cuts off the + after ignition feed but does not
cut off the forced after ignition feed timed mode. As long as one hour has not elapsed the + after ignition feed
function restarts the forced + after ignition feed for the remaining time. Vehicles: MEGANE II ph1 and ph2, SCENIC II ph1

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
A drop in engine speed followed by nominal behaviour from the vehicle is possible.
Special notes:
If this fault is present:
– It is impossible to start the vehicle,
– the level 1 warning light is illuminated.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.

NOTESCheck the conformity of the + 12 V after relay supply line,
from connection 3FB (Mégane II and Laguna II) or 3FB1
(Scénic II) of component 1337 or 597.
Use the vehicle Wiring Diagrams Technical Note.
Check the camshaft sensor connections.
Check the injection computer connections.
Check the camshaft sensor fitting and positioning,
Also check its general condition, (damaged housing, overheating, etc.),
Carry out the necessary repairs.
Check the continuity and absence of interference resistance of the following connections:
– connection codes 3CQ and 3FJ between components 120 and 746.
With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between connections 3FJ and 3FB (Mégane II and Laguna II) or 3FB1
(Scénic II) of the camshaft sensor:
The voltage displayed should be equal to the battery voltage ± 0.08 V.
– If the voltage is outside permitted tolerance values, take the measurement again on the connector, with the
camshaft sensor disconnected,
– If the voltage is still outside permitted tolerance values with the sensor disconnected.
Check thecontinuity and the absence of interference resistance on connection 3FB (Mégane II and Laguna
II) or 3FB1 (Scénic II) between components 756 and 1337 or 597.
If the measured voltage is correct with the sensor disconnected.
Measure the resistance of the camshaft sensor between connections 3CQ and 3FB (Mégane II and Laguna II)
or 3FB1 (Scénic II).
Replace the sensor if its resistance is not 9750 Ω < X < 10750 Ω at 20°C
If the connection or connections are faulty and 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.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
