ALP4The steering wheel does not return by itself to the centre at low
speed: steering wheel return to centre point inactive
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the casing under the steering wheel does not rub on the steering column or steering wheel.
Check the pressure and condition of the tyres, the condition of the joints and the front axle geometry.
Check the vehicle battery voltage.
Check the charge circuit if necessary.
Refer to 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).
Refer to parameters PR121 Steering wheel angle which must be in the range - 10 d˚ < X < 10 d˚ and PR007
Steering wheel angle offset compensation which must be in the range - 10 d˚ < X < 10 d˚.
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".
If parameters PR121, PR007 and status ET020 listed above are not in conformity:
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 REPAIRPerform a test using the diagnostic tool.

ALP6 Too little assistance
NOTESNote :
With the steering wheel on full lock, assistance is reduced after 0.5 seconds.
Check the pressure and condition of the tyres, the condition of the joints and the front axle geometry.
Check the vehicle battery voltage.
Check the charge circuit if necessary.
Do not operate the EPAS for at least 1 hour.
Check that parameters PR008 Computer temperature, PR009 Steering motor temperature and PR014
Assistance level available are correct (see Conformity check).
Make sure that no component located in the vicinity of the electric power-assisted steering system causes an
abnormal temperature rise in the system.
If the fault is still present, contact the Techline.
Note:
After the steering system has been heated a number of times, the EPAS limits assistance itself to protect its
electrical components.
It is normal for the system to do this.
AFTER REPAIRPerform a test using the diagnostic tool.

ALP8Assistance available but Check Steering warning message
displayed and Service indicator light continuously lit
NOTESNone.
Check the vehicle battery voltage and the condition of the electric power-assisted steering connector.
Repair and check the charge circuit if necessary.
Vdiag 05 and 09: Check status ET020 Steering wheel angle programming which should be STATUS 4. If not,
program the steering wheel angle sensor VP004 Steering wheel angle programming (see Configuration and
programming).
If the fault is still present, contact the Techline.
AFTER REPAIRPerform a test using the diagnostic tool.

ALP9 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 pressure and condition of the tyres, the condition of the joints and the front axle geometry.
Repair if necessary.
Vdiag 05 and 09:
Refer to 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).
Refer to parameters PR121 Steering wheel angle which must be in the range - 10 d˚ < X < 10 d˚ and PR007
Steering wheel angle offset compensation which must be in the range - 10 d˚ < X < 10 d˚.
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 parameters PR121, PR007 and status ET020 listed above are not in conformity:
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 REPAIRPerform a test using the diagnostic tool.
