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. RECAP
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:
–vehicle card in reader,
–press and hold the Start button (longer than 5 seconds) with the starting conditions not fulfilled,
–connect the diagnostic tool and perform the required operations. Vehicle(s): Mégane II, Scénic IIComputer name: PAS Computer
Program No.: from 8341
Vdiag No.: 04, 06, 08, 0C and 12
Special tooling required
Multimeter
Elé. 1681 Universal bornier
Note (for Mégane II only):
The left-hand and right-hand xenon bulb computers are powered when the dipped headlights are lit. Fault finding
can only be run on them after the ignition has been switched on in fault finding mode (forced + after ignition feed)
and the dipped headlights are on.

Fault finding - Configurations and programming
VP004: STEERING WHEEL ANGLE SENSOR PROGRAMMING
NOTESThis programming procedure is performed after replacing the EPAS computer.
WARNING
Programming the steering wheel angle sensor means programming the 0 angle (wheels straight ahead position).
It must be done for any blank computer, and every time it is requested in this note.
The absence of or incorrect programming of this sensor will illuminate the Service warning light and create an
Electronic Stability Program fault.
OPERATIONS TO PERFORM BEFORE PROGRAMMING
–With the ignition on or engine running (to obtain maximum steering assistance), turn the steering wheel to full
left lock and then to full right lock,
–position the vehicle with the wheels straight ahead and the steering at the centre point (driving in a straight line),
–run the command by pressing the CONFIRM button,
–while the COMMAND IN PROGRESS message is displayed, turn the steering wheel a quarter of a turn from left
to right.
–Once the COMMAND COMPLETE message is displayed, exit fault finding mode (close dialogue with the
computer without switching off the tool) and then switch off the vehicle's ignition for 15 seconds minimum for
the programming to be registered.
Note:
To obtain a precise position with the wheels set straight ahead (driving in a straight line), this operation must be
performed on a front axle adjustment bench (especially for vehicles fitted with ESP).
OPERATIONS TO PERFORM AFTER PROGRAMMING
–Switch on the ignition and establish dialogue with the EPAS computer,
–turn the steering wheel to full left lock and then to full right lock,
–check that the programming has been properly registered: ET020 Steering wheel angle sensor programming
should be STATUS 4,
–check the conformity of the angle value by consulting parameter PR121 Steering wheel angle,
–check that there are no faults,
–carry out the necessary repairs, consulting the fault finding manual.
IMPORTANT
If the vehicle is fitted with ESP, establish dialogue with the ABS/ESP computer after the operation; if the function
is available (depending on computer version) clear the ESP sensor programming using command RZ003.
Make sure there are no ESP faults: make the necessary repairs, consulting the fault finding manual.

SC001: COMPUTER CALIBRATION
NOTESThis configuration is performed after replacing the EPAS computer.
WARNING
The computer is supplied with the default calibration 0.
An incorrect configuration may damage the function.
Command SC001 is used to define the vehicle specifications.
The configuration is determined by the following specifications:
–Vehicle type:
–The diameter of the vehicle wheel rims:
–The vehicle engine type and gearbox type:
CALIBRATION PROCEDURE:
–Connect the diagnostic tool and select EPAS,
–select command SC001 Computer calibration,
–configure the computer in line with the vehicle definition,
–exit fault finding mode without switching off the tool (close the application only),
–switch off the ignition,
–wait 15 seconds for the end of power-Iatch then restart,
–make sure that the configuration reading corresponds to the desired calibration:
LC005 or ET026 Computer calibration.
