PR001
TORQUE APPLIED TO THE STEERING WHEEL
NOTESNone.
This parameter indicates the torque applied by the driver to the steering column.
If the parameter does not conform with the values indicated in the Conformity check, consult the interpretation of
fault DF054 Torque sensor.
AFTER REPAIRPerform a test using the diagnostic tool.

MOTOR POWER (60 A)
CURRENT SETPOINT (60 A)
NOTESNone.
Parameter PR131 Current setpoint (60 A) indicates the current setpoint (power) sent by the EPAS computer to
the steering motor according to the torque applied to the steering wheel. Parameter PR129 Motor power (60 A)
indicates the electric current actually consumed by the EPAS motor.
The value of parameter PR131 Current setpoint (60 A) must be approximately equal to the value of parameter
PR129 Motor power (60 A).
If the parameters are not the same, contact the Techline.
AFTER REPAIRPerform a test using the diagnostic tool.

ALP 7 PERMANENT ASSISTANCE
NOTESOnly consult this customer complaint after a complete check with the
diagnostic tool.
Check the conformity of the computer and the steering column (45 or 60 A) in relation to the table below:
Left-hand drive Right-hand drive
Torque sensor wiring harness blue black
Motor wiring 45 A green black
Motor wiring 60 A blue grey
45 A 60 A
ECU label yellow white
In the event of non-conformity, consult RENAULT NET to repair the vehicle according to the technical vehicle
definition.
Check that the configuration reading LC002 Strategy number corresponds to the vehicle equipment.
Configure the computer correctly using the diagnostic tool, if necessary (see Configuration).
Check the pressure and condition of the tyres, the condition of the joints and the front axle geometry.
If the fault is still present, contact Techline.
AFTER REPAIRPerform a test using the diagnostic tool.

ALP 9 STEERING WHEEL VIBRATION OR PULSATING
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Use the Technical Note wiring diagram for New Twingo.
Connectors of component 502 disconnected, check the condition and conformity of the connectors and clips.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
With the connector of component 1016 disconnected:
Check the continuity and insulation of connection AP23 between components 502 and 1016.
Check the continuity and insulation of connection ML of component 502.
If the connection or connections are faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
If the checks reveal no faults, perform a conformity check of component 1016.
Check the conformity of PR001 Torque applied to steering wheel (see Conformity check).
If the value of this parameter changes drastically without any movement of the steering wheel, contact the
Techline
Check the conformity of PR129 Motor power (60 A) or PR130 Motor power (45 A) (see Conformity check).
If the value of this parameter changes drastically without any movement of the steering wheel, contact the
Techline.
If the incident is still present, contact the Techline.
AFTER REPAIRPerform a check using the diagnostic tool.
