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.

PR001
TORQUE APPLIED TO THE STEERING WHEEL
NOTESNone.
This parameter indicates the torque applied by the driver to the steering column. It is positive when the steering
wheel is turned to the right and negative when it is turned to the left.
If the parameter does not conform with the values indicated in the Conformity check, refer to the interpretation of
fault DF054 Torque sensor.
AFTER REPAIRPerform a test using the diagnostic tool.

PR007
STEERING WHEEL ANGLE DRIFT COMPENSATION
NOTESNone.
This parameter shows the correction of the angle value, implemented automatically by the EPAS computer. When
driving, if the steering wheel angle in the straight-ahead driving position is not 0˚, this parameter varies (offset from
the steering wheel angle value).
If the value of the parameter is different to 0 d˚ (± 10 d˚), check the value of parameter PR121 Steering wheel
angle with straight wheels, if PR121 > ± 10 d˚ program the steering wheel angle using command VP004 Steering
wheel sensor programming (see Configuration and programming, section C).
If PR121 < ± 10 d˚ and the vehicle is fitted with ESP, place the vehicle on a geometry test bench (front axle test
bench).. Position the vehicle wheels in the straight line driving position (steering centre point).
Program the steering wheel angle using command VP004 Steering wheel angle sensor programming (see
Configuration and programming).
AFTER REPAIRPerform a test using the diagnostic tool.

PR121
STEERING WHEEL ANGLE
NOTESNone.
This parameter shows the steering wheel position in relation to the programmed zero (performed by command
VP004 "Steering wheel angle sensor programming").
This parameter is positive to the right and negative to the left.
If the angle remains at 3696˚, either:
–the steering wheel angle programming has not been carried out (ET020 Steering wheel angle programming
is STATUS 1 or STATUS 2),
–or the steering wheel is outside the range ± 120 d˚ (ET020 Steering wheel angle programming is STATUS 3),
when the APC is switched on, therefore the angle is valid; the angle is STATUS 4 only if the steering wheel is
within the range ± 120 d˚. As the sensor's coverage is not complete, it needs to come within this zone to detect
its position.
Thus, when the APC is switched on, if the steering wheel is not within the range ± 120 d˚ then the angle is invalid
(ET020 Steering wheel angle programming is STATUS 3). Simply rotating the steering wheel so that it is in the
± 120 d˚ range will allow a valid angle to be found (ET020 Steering wheel angle programming is STATUS 4),
when the EPAS is operating correctly,
–the sensor is faulty DF038 Angle sensor.
If the angle remains at 3696˚, with action on the steering wheel and status ET020 Steering wheel angle
programming is STATUS 4, contact the Techline.
If the parameter does not correspond to the values shown in the Conformity check, place the vehicle on a
geometry test bench (front axle bench). Position the vehicle wheels in the straight line driving position (steering
centre point).
Program the steering wheel angle using command VP004 Steering wheel angle sensor programming (see
Configuration and programming).
AFTER REPAIRPerform a test using the diagnostic tool.

Run fault finding on the multiplex network.
Check the voltage of the vehicle battery (the EPAS system only reacts between 10 V and 18 V).
Repair if necessary.
Try the diagnostic tool on another vehicle.
Check:
–the connection between the diagnostic tool and the diagnostic probe (lead in good condition),
–the connection between the diagnostic sensor and the diagnostic socket (lead in good condition).
Check the condition of the EPAS fuses and their contacts:
80A BP81 Power fuse in the engine fuse box.
5A AP44 + after ignition fuse on the UPC.
Check for the presence of + 12 V battery feed on track 16, and + 12 V after ignition feed on track 1 and an earth
on track 5 and on track 4 of the diagnostic socket.
Repair if necessary.
Disconnect the two EPAS computer connectors.
Check the condition and conformity of the connectors and their clips.
Check the conformity of the electrical supplies (they must be equal to the battery voltage).
Electric Power Assisted Steering Computer Connector:
2-track connector track 1+ battery feed
