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.

ALP1 No dialogue with the computer
NOTESNone
Check the vehicle's battery voltage.
Repair if necessary.
Try the diagnostic tool on another computer on the same vehicle, or on a different vehicle.
Check the condition of the 5A fuse on the UPC (shared between Electric power-assisted steering and Airbag) and
attempt to run fault finding on the system.
If the condition of the fuse is not the cause, carry out the following operations:
–activate forced + after ignition feed or have the engine running,
–disconnect the Electric Power Assisted Steering power connector,
–check the connection by pushing and pulling the connector,
–try running fault finding again using the tool,
–if dialogue can be established the fault is repaired,
–if the fault is still present, apply the following procedure.
Check the electric power-assisted steering and engine compartment fuses (70A) and the passenger compartment
fuse (5A).
Check the continuity and absence of interference resistance on the wiring harness between the battery and
the variable power assisted steering computer:
Black 2-track connector track 1 + Battery
Black 2-track connector track 2 Battery 0 V
Black 8-track connector track 8 + After ignition
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise change the wiring.
Run fault finding on the multiplex network.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

ALP3 Poor vehicle handling
NOTESNone
Check using status ET026 Computer calibration that the computer configuration corresponds to the vehicle
equipment, wheel size, vehicle type and engine:
Configure the computer correctly using the diagnostic tool, if necessary (see SC001 Computer calibration).

Check the condition and pressure of the tyres, the condition of the joints and the front axle geometry.
Check the vehicle battery voltage and the condition of the battery terminals.
Repair if necessary.
Check the condition and presence of the electric power steering supply fuse.
Repair if necessary.
Check the condition of the electric power steering black 2-track power connector.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector, otherwise change the wiring.
If the fault is still present, contact the Techline.
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.
