4) Move the vehicle back, turning
the wheels through 90° (the closer the rota-
tion to 90°, the greater the accuracy of the
compensation) and press the ROC key on one
of the sensors. LED 2 (I fig. 25) will start to
flash. It stops flashing once the initial values
have been memorised; this occurs once the
values are stable.
5) Move the vehicle forward to the
initial position and press the ROC key. Press
the ROC key on one of the sensors.
6) If the final position values are too different
from the initial values, a procedural error
is signalled. LEDs 1 and 2 will
remain on; press the ROC key to repeat the
compensation. If the procedure is correct it
ends automatically.

rear sensors at a later point.
N.B. Any geometrical errors in the rim or clamp
mounting errors will not be considered.
In some conditions (e.g. cars with rigid suspen-
sion systems and alloy rims) it is advisable to
skip the compensation procedure because after
the car has been lifted the suspensions may
settle into a position different from the normal
operating position.
This may generate errors of a greater magnitude
than those caused by a misshapen rim.

sensors only; it will not be possible to use the
rear sensors at a later point.
N.B. This procedure is only recommended when
the sensors have not been removed from the
wheels, but it has been necessary to restart the
alignment procedure for some reason.
ROC x 1
Compensation can also be repeated on just
one wheel.
ROCx1 is used when a wheel has been removed
during wheel alignment operations. In this case,
perform the operations as described in points
1-7 of the 2-POINT ROC section from any axle
adjustment screen.
N.B. Any geometrical errors in the rim or clamp
mounting errors will not be considered.
In some conditions (e.g. cars with rigid suspen-
sion systems and alloy rims) it is advisable to
skip the compensation procedure because after
the car has been lifted the suspensions may
settle into a position different from the normal
operating position.
This may generate errors of a greater magnitude
than those caused by a misshapen rim.
Compensation correction
This procedure allows measurement of the
amount by which the wheel has rotated in rela-
tion to its final position during compensation,
for example when the car is lowered on the lift
after the compensation procedure.
Keep the ROC key (B fig.25) on the sensor which
is out-of-level until the LEDs 1 and 2 (G and I
fig.25) remain constantly on.
Release the sensor's brake and level it.
Press the ROC key to terminate the operation;
LEDs 1 and 2 go out.
