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.

STARTING WITH WHEELS TURNED (OUTSIDE RANGE ± 120˚) (only for Vdiag 05 and 09)
When starting the engine with the wheels fully locked (outside range ± 120˚), status ET020 Steering wheel angle
sensor programming is STATUS 3. No fault is indicated by the EPAS or ESP and no indicator light comes on, as
this is a basic operation of the system.
In order for status ET020 to be STATUS 4 turn the wheels so that they are straight (normal operating range).
B. CONFIGURING THE STEERING ASSISTANCE STRATEGY
This configuration enables the computer's assistance strategy to be calibrated depending on the vehicle type, engine
type, gearbox type and tyre sizes.
–with the ignition on, connect the diagnostic tool and establish dialogue with the electric power assisted steering
computer,
–run command SC001 Computer calibration by pressing the CONFIRM button,
–enter the criteria corresponding to the vehicle,
–check, using status ET026 Computer calibration, that the criteria that have been entered correspond
to the vehicle.
