If after a complete checking of the anti intrusion system,
the replacement of the E.C.U. anti
intrusion is required, proceed as follows:
- remove from the central console the tape recorder’s frame and the tape recorder pulling
backward but without disconnecting the tape recorder from the vehicle’s wiring;
- dismount by detaching the aeration grill located on the right side of the central console ;
- dismount the t wo screws attaching t he E CU support i n t he ri ght side of the climate
control unit;
- take off the anti intrusion ECU together with its support through the central zone of the
central console; - disconnect the 24 ways connector from the anti intrusion ECU proceeding as follows:
remove towards exterior the two blocking clips of the connector and then carefully pull out the
connector; - dismount carefully the two way connector from the anti intrusion ECU;
- dismount the two screw attaching the anti intrusion ECU on its support;
- proceed the in reverse order of the dismounting;
- check the proper operation of the anti intrusion system. DISMOUNTING – REMOUNTING

DISMOUNTING-REMOUNTING OF TH E WINDSCREEN
WIPER MECHANISM
The windscreen wiper mechanism is mounted into the climate control box. This one, and his
components too, are in the next detailed drawing.
DISMOUNTING Disconnect the battery.
Release the protectors (A) from the axles.
Di smount the attachment nut ( B) of the
windscreen wiper mechanism’s arms and blades.
Dismount the attachment nut (C) of the axles from the windscreen’s lower frame; recuperate
the ruber gaskets and retaining washers.
Disconnect the wirring connectors from the windscreen wiper electric motor.
Dismount the mechanism’s attachment screw on the lower traverser windscreen.
Get off the mechanism.
REMOUNTING
Perform the dismounting operations in the reverse order.
NOTE:
When mounting the windscreen wiper mechanism’s arms the windscreen wiper
electric motor will be aligned in“stopped at fix point”.

RTICULARITIES REGARDING THE CONNECTORS
DISCONNECTING METHOD
Because this vehicle is equipped with electronics systems controlling and checking different
functions, it is necessary the execution of the electric connection by means of some connectors
provided with securing de vices after coupling performing. Due t o this reason, i n c ase t heir
disconnecting is necessary, proceed observing the following observations:
- connectors for: ignition coil (pos.1), canister purging valve (pos.2), AC pressure sensor (pos.3),
atmospheric pre ssure sensor(pos.4), siren(pos.4), step-by-step engine (pos.5), valve potentiometer
(p os.6), cooling blower (pos.7) are to be disconnected after easy pulling the locking clamp in the
di rection shown by the arrow.
- the connectors for: RPM sensor (pos.8), front hood contact (pos.9) are to be disconnected
after easy pulling the locking clamp (A) in the arrow direction, for unlocking.
