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
Special tooling required
3. REMINDER
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 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),
–ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the instrument
panel have gone out. Vehicle(s): Scenic II

Fault finding – Configurations and programming
Summary table of configurations and configuration readings
GENERAL INSTRUCTIONS:
After replacing the EPAS computer/steering column unit, configure the computer's assistance strategy and program
the steering wheel angle sensor (only for Vdiag 05 and 09).
The following procedure must be followed in order to carry out the above configuration and programming:
–connect the diagnostic tool,
–switch on the ignition and establish dialogue with the electric power-assisted steering computer,
–select the "Repair mode" menu,
–configure the computer's assistance strategy and program the steering wheel angle sensor (see below),
–exit fault finding mode: stop dialogue with the electric power assisted steering computer without switching off the
CLIP tool,
–switch off the ignition for at least 15 seconds, without disconnecting the battery, for the configuration to be taken
into account by the EPAS computer,
–switch on the ignition again and establish dialogue with the electric power assisted steering computer,
–make sure the configuration readings have been properly registered,
–check that the system is operating correctly (steering assistance available when the engine is running).
A. STEERING WHEEL ANGLE SENSOR PROGRAMMING (only for Vdiag 05 and 09)
PROCEDURE COMPLETE:
(following replacement of the computer/steering column assembly).
Status ET020 Steering wheel angle sensor programming is STATUS 1 (SERVICE indicator light is continuously
lit, see interpretation of status).
–with the ignition on, connect the diagnostic tool and establish dialogue with the electric power assisted steering
computer,
–with the engine stopped or running (to obtain maximum steering assistance), turn the steering wheel to full left lock
and then to full right lock,
–set the vehicle wheels straight ahead, with the steering at the centre point (driving in a straight line),
–run command VP004 Steering wheel angle sensor programming by pressing the CONFIRM button,
–turn the steering wheel to full left lock and then to full right lock,
–Status ET020 Steering wheel angle sensor programming must be STATUS 4 (normal operational status),
–check that parameter PR121 Steering wheel angle varies within the limits indicated in the Conformity check
section and that DF038 Angle sensor is not present. VP001 Enter VIN ID010 VIN code
VP004Steering wheel angle sensor programming
(only for Vdiag 05 and 09)ET020Steering wheel angle sensor programming
(only for Vdiag 05 and 09)
VP005 Enter the APV* operation date ID018 Read last APV* operation date
SC001 Computer calibration ET026 Computer calibration
Note:
To obtain a precise wheels straight ahead position (straight line driving), carry out this operation on a front axle
adjustment bench (especially for vehicles fitted with ESP).
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 the computer version) clear the ESP sensor programming using command RZ003.
Make sure there are no ESP faults: carry out the necessary operations by referring to the Fault Finding Manual.

PROGRAMMING THE STEERING WHEEL ANGLE SENSOR
NOTESSpecial note:
–This status is declared correct when it is STATUS 4 (normal mode); in any other
case, apply this fault finding procedure.
–The SERVICE indicator light will come on if the steering wheel angle calibration has
not been carried out.
VARIOUS POSSIBLE STATUS VALUES (with the meaning):
STATUS 1:
–Straight ahead wheel position not programmed.
–Invalid angle value.
PROGRAMMING NOT COMPLETE.STATUS 3:
–Straight ahead wheel position not programmed.
–Invalid angle value.
–Steering wheel out of range ± 120˚ when after ignition
is switched on.
PROGRAMMING COMPLETE, ANGLE TO BE
CONFIRMED.
STATUS 2:
–Straight ahead wheel position not programmed.
–Invalid angle value.
PROGRAMMING NOT COMPLETE.STATUS 4:
–Straight ahead wheel position not programmed.
–Valid angle value.
PROGRAMMING COMPLETE.
STATUS 1 or STATUS 2
If the status is STATUS 1 or STATUS 2, program the steering wheel angle (see Configuration and
programming).
STATUS 3
If the status is STATUS 3, turn the steering wheel from right lock to left lock then slowly return it to slightly beyond
the centre point (PR135 "Column rotation speed" less than 200˚/s). The status should become STATUS 4.
Note:
A present or stored fault can impede STATUS 4 (carry out the necessary operations by referring to the Fault
Finding Manual).
AFTER REPAIRPerform a test using the diagnostic tool.
