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.
