YAW SENSOR
Refitting
Disconnect the battery cables in the engine compartment.
Take off the instrument board covering.
Figure 97
Replacing the yaw sensor requires no calibration
procedure.
Unscrew the two sensor (2) fastening screws (1) by using a
suitable wrench to remove the side right screw, considering that
the latter cannot be accessed easily. Then, remove sensor (2).
!
Take off glove compartment (1) on the passenger’s
side. If the vehicle is equipped with passenger’s
airbag, follow the safety rules indicated in the
relevant chapter of the “Steering” section.
Re-attachment is carried out by reversing the order
of detachment operations. Also follow the advice

Replacing the modulator/control unit requires calibration of
the longitudinal acceleration sensor (described on page 64).
In this case, the steering angle sensor shall not be calibrated
since it features its own internal memory.
Re-attachment is carried out by reversing the order of
detachment operations. Also follow the advice below:
- connect the connector with great attention, taking care
to insert it perpendicularly to the seat to avoid damaging
the pins;
- after re-attachment has been completed, perform the
programming and calibration procedures described
below.

Programming
Programming requires entering the following variant codes
(by means of the diagnosis instrument): type of drive, engine,
MTT, wheelbase, type of front and rear suspensions, height.
Easy compares the type of vehicle (PIC reading) with the
control unit code to avoid installation errors (single wheels
instead of dual wheels), and downloads the variant codes into
the control unit.
