Under steering wheel control
The under steering control assembly and the rotating contact included in this one are not to be
separated. The rotating contact is ensuring the electric connection between the steering column
and the steering wheel. This contact is connected with the from wiring by means of wires stacked
as tape-shaped having the necessary length provided to ensure 5 steering wheel rotations (limited
by the wheels camber plus one more for safety).
DISMOUNTIN G
AT T E N T ION !
It is forbidden the handling of the pyrotechnic system (airbag) near heating sources
or open fire, because there is a risk of undesirable starting of the system.
IMPORTANT !
Anytime when dismounting t he steering wheel, it i s necessary to dismount the airbag
connector (1). The airbag is provided with a connector who is short-circuited aft er
disconnecting the wiring connector, avoiding in this way all undesirable starting. Block the UCE airbag by means of the CLIP tester (see chapter 88 “ UCE airbag blocking” ).
The airbag indicator from the instrument panel is on. Disconnect the battery (-) terminal.
Set the steering on the middle point (straight on driving position of the vehicle).
Dismount the two attachment screws T ORX 20 of the airbag to the steering wheel.
Dismount the airbag connector ( 1).
Dismount the steering wheel attachment screw.
Carefully dismount the steering wheel for not damaging the “tape” connector of the rotating
contact; ensure that wheels are in straight-on vehicle driving position.
Dismount the three attachment screws TORX 20 of the steering wheel half-cases.
Detach from clips the steering wheel half-cases and remove them.
Disconnect the windscreen wiper connector, the lights and turning control connector and the
rotating contact connector. Loosen the screw (2 ) unblocking in this way the under steering wheel control assembly from
the attachment cone of the steering column.
Extract the under steerin g wheel control assemb ly off the attachment cone of the steerin g c olumn.
AT T E N T I ON !
It is forbidden the changing of the rotating contact position after dismounting the
under steering wheel control assembly because there is the risk of its damaging. The under steering wheel control – new i tem number- is provided with a pre-c ut
s elf-adhesive tape, stacked on the rotating contact and on the under steering wheel
control body that is not allowing the undesirable rotation of the rotating contact until
its m ounting on the attachment cone of t he steering column.

Tighten t he screw ( 2) so that i s blocking the under-steering wheel control on the steering
column. This operation is facilitated by a cutting-out in the lower half-case allowing the access to
the screw ( 2).
Carefully mount the steering wheel in order not to damage the “tape” connector of the rotating
contact, the steering wheel is having an area with no grooves, that must be corresponding to the
no-grooves area from the steering column. The steering wheel must easy enter in the grooves.
Replace the steering wheel attachment screw (TORX 50) after each dismounting and tighten
it to the required moment ( 4.4 daNm).
Reconnect the airbag connector (10.
M ount the two attachment screws TORX 20 of the airbag (required tightening moment is
0.65 daNm) Reconnect the battery (-) terminal.
Check the operation of the under steering weel control.
IMP ORTANT !
Before reconnecting the driver’s ai rbag connector, it is necessary to apply a check-
ing procedure of the system: - check if the airbag indicator from the instrument panel is on, when the contact
is set on; - connect the inert igniter to the airbag connector (to the wiring) and check if the
airbag indicator is off; - set the contact off, connect the airbag connector instead of the inert igniter and
attach the airbag on the steering wheel (required tightening m oment is 0.65 daNm). AT T E N T I ON !
Any doubts regarding a good centering of the rotating contact involves the applying
of its centering method: carefully rotate clockwise the upper part of the rotating con-
tact 2.5 complete rotations (or until it gets blocked), then rotate anti-c lockwise 2.5
complete rotations. In case of a steering dismounting operation, of t he engine or of the t ransmission
elements implying the steering rack or steering column uncoupling, the steering wheel
must be immobilized. After everything has been remounted, perform an airbag system checking by means
of the CLIP tester. If everything is correct, unblock the UCE airbag and check if the
airbag indicator from the instrument panel is on for 3 seconds from setting the contact
on, then it is off and is remaining off. If the airbag indicator is not operating as a.m .,
see chapter “Diagnostic” and check the system by means of the “CLIP” tester. AT T E N T I ON !
All non-observing of these prescriptions may c ause an abnormal operation of the
sy stem, even an undesirable starting of it.

AIRBAG OPERATION
When setting the contact on, the airbag system
control indicator from the instrument pa nel is
lighted for 3 seconds then it is off.
UCE airbag is entering in a lookout state and
is considering the vehicle decelerations due to a
s ignal m easured by an integrated e lectronic
decelerometer.
In case of a stronger frontal impact, the
security electromechanical captor is tripping the
igniter of the pyrotechnic gas generator, which is
inflating the driver’s airbag. The airbag system is not releasing in case of a
s ide impact or a re ar impact.
When started, the pyrotechnic gas generator
is generating a detonation and some smoke.
IMPORTANT!
This system must be checked by means of the
CLIP tester, immediately when:
-a n accident did not caused the
movement, -the ve h icle was stolen or a stilling tentative
has been produced. -before selling a second hand vehicle.
AIRBAG INDICATOR FROM INSTRUMENT PANEL
This indicator is showing the operation state of
the driver’s airbag.
It is lighted for 3 seconds from contact setting
on, and then it is getting off and it staying like this.
If it is not on when setting the contact on or it is
on during vehicle driving, this is indicating a failure
in the system (see chapter “Diagnostic”) .
After driver’s airbag releasing, the airba g
indicator from the instrument panel is on and UCE
airbag is automatically bl oc king the driver’s airbag releasin
g line, memorizing the releasin g.
That is why, after an impact generating the
airbag re leasing, i t is necessary the UCE
airbag unblocking, then the computer blocking
in order to block all releasing.
The erasing of the memorized failures it is
possible only aft er data reading from “Im-
p act context” , then the shock sensor con-
tact is restored and the c ontrol “Computer
unblocking” may be performed.
UCE AIRBAG
DISMOUNTING – REMOUNTING
UCE airbag is mounted on the tunnel in
front of the gearbox lever. UCE air bag is provided with: -a security electromechanical captor,
-a decelerometer for airbag
- an ignition circuit of the pyrotechnic
system -an electric energy reserve,
-a diagnostic and memorizing circuit
of the detected failures, -a control circuit of the alert indicator
from instrumen t panel.
-A K-L communication interface with
the diagnostic socket.
UCE AIRBAG BLOCKING

AT T E N T I ON!
N on-observing of these prescriptions may
ge ne rat e an abnorm a l ope rat i on of t he
sy stem, even undesirable releasing of the
airbag. UCE airbag may accept up to maximum
4 ai rbag re leasing (c ert ai n e lements are
loosing their nominal characteristics). It is
n ot necessary the systematic replacement
after each airbag releasing.
UCE AIRBAG UNBLOCKING
Af ter replacing UCE airbag it is necessary
the re leasing lines unblocking. The same
method as for the UCE airbag blocking is to
be used, by validation c ontrol “ Computer
unblocking”. The airbag indicator from the
instrument panel is getting off.
REMARK:
The 30 pins connecto r of the UCE
airbag has a shunt circuit that is short-
circuiting the different transmitting
lines of the releasing signal when this
one is disconnected, avoiding the
undesirable releasing of this system (by
antenna effect, for instance)
REMARK:
UCE airbag supply and the
pyrotechnic gas generator is performed
by means of the vehicle bat tery. UCE
airbag is disposing of a reserve electric
energy enabling nevertheless the airbag
r eleasing even if, at the be ginning of a
shock, the v ehicle battery i s not anymore
supplying the UCE airbag.

REMARK : By means of the CL IP
tester it is possible the visualization of
the releasing of the driver’s ai rbag.
If the airbag has been tripped: -replace the releasing elements and the
defective ones;
-check the failures absence by means
of the CLIP tester;
- check the necessity of UCE airbag
replacement.
When everyt hing is correct, unblock the
UC E air bag and the system is again
operational (the airbag indicator is getting off).
If t he CL IP t est er i s sti pul ati ng the
