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.

LC005: COMPUTER CALIBRATION
Reading configuration LC005 enables you to check that the computer calibration corresponds with the vehicle type
undergoing fault finding.
The values of LC005 are interpreted in ET026 (see Interpretation of statuses).
If the calibration is not to your satisfaction, use command SC001 to redefine the vehicle specifications.

WARNING
Consult the fault contexts.
If PR143 Internal fault codes = 46 and the battery voltage when the fault occurs (PR108) is above 9 V, do not
clear the fault; contact the Techline.
If PR143 Internal fault code = 46 and the battery voltage when the fault occurs (PR108) is less than or equal to
9 V, run fault finding on the battery and charge circuit and clear the fault.
For other values of PR143, do not clear the fault, contact the Techline.
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after starting or a steering wheel movement from full lock
to full lock.
–Check the condition and connection of the battery terminals.
–Check that the EPAS black 2-track connector is correctly locked.
–Check that the EPAS black 8-track connector is correctly locked.
–Check the condition and conformity of the EPAS fuses: on the power fuse board (70A) and on the UPC (5A).
–Check the conformity of PR108 Computer feed voltage: 12 V < PR108 < 16 V.
Check that:
–there is a + 12 V before ignition feed on track 1 of the electric power steering black 2-track connector,
–there is an earth on track 2 of the electric power steering black 2-track connector,
–there is a + 12 V after ignition feed on track 8 of the steering column assembly black 8-track connector.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.
