PROGRAMMING THE STEERING WHEEL ANGLE SENSOR
NOTESSpecial notes:
–The status is declared as correct when it is STATUS 4 (nominal mode). Otherwise,
apply this fault finding procedure.
–An unprogrammed steering wheel angle sensor will cause the Service warning light
to come on.
–If the steering wheel angle sensor has never been programmed, the Service warning
light will flash rapidly until the index position is detected.
VARIOUS POSSIBLE STATUS VALUES (with the meaning):
STATUS 1–Steering wheel index not detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–NOT PROGRAMMED: Program the steering wheel angle sensor.
STATUS 2–Steering wheel index detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–NOT PROGRAMMED: Program the steering wheel angle sensor.
STATUS 3–Steering wheel index not detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–PROGRAMMING DONE, CONFIRM ANGLE: Turn the steering wheel to right full lock, and then
left full lock; then slowly return to the centre point and go slightly beyond.
STATUS 4–Straight ahead wheel position not programmed.
–Valid angle value.
–PROGRAMMING COMPLETE
Note:
A present or stored fault may prevent the change to STATUS 4.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.

CONTINUED
STATUS 1 OR STATUS 2
If the status is STATUS 1 or STATUS 2, program the steering wheel angle sensor (see Configurations and
programming).
STATUS 3
If the status is STATUS 3, turn the steering wheel to right full lock, and then left full lock; then slowly return to the
centre point and go slightly beyond.
Status ET020 should become STATUS 4.
Note:
A present or stored fault can impede STATUS 4 (make the necessary repairs, consulting the fault finding manual).
After the battery is disconnected, status ET020 is STATUS 3 and PR121 Steering wheel angle remains 0.
Consult the Replacement of components section for the procedure to follow after disconnecting the battery.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.

STEERING WHEEL ANGLE
NOTESNone
The steering wheel angle, positive to the right or negative to the left, is the position of the steering wheel relative
to the zero value set when the steering wheel angle sensor is programmed.
If the parameter is not in line with the conformity check values (- 580˚ < X < 580˚), consult interpretation of faults
DF038 or DF059 Angle sensor.
Note:
If the angle remains 0˚:
–The steering wheel angle sensor has not been calibrated (status ET020 at status 1 or 2),
–the procedure to apply after disconnecting the battery was not observed,
–a fault is present. Deal with this fault.
AFTER REPAIRCarry out a road test, followed by a check with the diagnostic tool.

ALP4The steering wheel does not return by itself to the centre at low
vehicle speed: steering wheel self-centring inactive
NOTES
Check the condition and pressure of the tyres, the condition of the joints and the axle geometries.
Check the vehicle's battery voltage.
Repair if necessary.
Check that the steering wheel angle sensor is correctly calibrated and consistent with the position of the steering
wheel (status ET020 at status 3 or 4 and PR121 at 0˚ ± 5˚ with wheels set straight ahead).
Program the steering wheel angle again if necessary (see VP004 Steering wheel angle sensor programming).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

Repair if necessary.
Check the steering wheel angle sensor programming (ET020 = STATUS 4)
If the sensor is not calibrated, program the steering wheel angle sensor (procedure VP004 Steering wheel angle

ALP10 The vehicle pulls to the right or to the left
NOTESNone
Check that the casing under the steering wheel does not rub on the steering column or steering wheel.
Check the tyre pressures and the condition of the joints and the steering geometry.
Repair if necessary.
Check status ET020 Steering wheel angle sensor programming, which must be STATUS 4.
Position the vehicle wheels in the straight line driving position (steering centre point).
Consult parameter PR121 Steering wheel angle which must be between - 10d˚ < X < 10d˚.
Turn the steering wheel to full right lock then to full left lock, and check that the parameter varies within the
tolerances given in the Conformity check.
Check the position of the steering wheel on the splines of the steering column.
If parameter PR121 Steering wheel angle and status ET020 Steering wheel angle sensor programming listed
above are not correct:
Place the vehicle on a front axle adjusting 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).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check using the diagnostic tool.
