SUGGESTIONSDo not use this information before having done the complete
check- up with the tester!
Check if there are no broken tubes
Check if the air filter is not deformed.
Check the condition of the fittings.
Check if the exhaust collector is watertight.
Make sure that, after taking them off, the injectors do not leak.

Check if there are no broken tubes
Check the state of the sparking plugs and the ignition coil.
Check if there is petrol in the fuel tank (do not rely on the
on-board in dices). Check if it is the fuel recommended by
the manufa cturer. Check if there are no broken tubes.
Check if the exhaust circuit is not strangled-up and the
cata lyst is not stopped-up.Check the exhaust

Check if the clapper body is not clogged.
Check if there are cases of lack of watertightness (noise)
on the powe r-brakes.
Connect the tester “CLIP” and do the test corresponding
to the check-up of the rotation signal.
Check if the spurs, the brake cylinders and the wheel ball-
rings are no t seized-up.Check the body o f

Check the canister
draining valve Disconnect the tube between the draining valve and the in-

(STARTING – IGNITION SWITCH)
The anti theft mechanism is placed on the right part of the steering column and has the purpose
to starter control when electric system is connected, being provided in the same time also with a
steering locking device, with anti theft lock.
NOTE
At the anti theft mechanism there is not any more marked G position (garage) because
it does not allow the taking out of the key in this position but helps in pi n unblocking
for removing the mechanism from the steering column.
Disconnect the battery.
Dismount the steering wheel casings.
Disconnect the anti-starting bushing.
Remove the bushing off the steering column.
Disconnect the switch connection wires.
B ring the key in the interme diary position (ex G).
Dismount the attachment screw (1).
P ush the mobile pin ( 2) and pull backwards
the switch.
REMOUNTING
Mount the switch in its place.
Tighten the attachment screw(1).
Connect :
- the switch
- the battery.
Position and mount the anti-star ting bushing.
Connect the anti-starting bushing to the ve-
h icle wirin g.
Check the switch operation.
Mount the steering wheel casings. DISMOUNTING

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.
