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.

Ensure that steering is on middle point (wheels are in the straight-on driving position of the
ve h icle).
Position the under-steering wheel control assembly so that after remounting the two steering
wheel half-cases, the assembly handles are lined up with the instrument panel and the dashboard.
Reconnect the windscreen wiper connector, the lights and turning connector and the rotating
contact connector. Attach in clips the steering wheel half-cases.
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 - General
IMPORTANT!
All intervention on the airbag system
may be performed only by qualified staff.
The Dacia SOLENZ A vehi c les a re
equipped with a pa ssive securi ty system
composed of: -a driver frontal airbag with an inflata bl e
bag, -UCE airba g mounted in t he c entral
console tunnel.
In case of a front impact strong e nough,
theUCE airbag is releasing the airbag, which
is inflating in the steering wheel central part,
protecting in this way the driver’s face. The airbag is not reacting at decelerations
in t he dri ving di rection. A side impact or a
rollover may not lead to the airbag releasing. The vehicle projection energy is
transformed i nto distort ion energy of the
vehicle front part. The higher deceleration is,
the smaller vehicle distortion is, and the airbag
is quicker releasing.
The minimal speed at which the airbag is
releasing is increasing, a s the i mpact angle
between the vehicles is higher. If in case of a front al impact there are no
distortions in front of the front pedals support or
engine-frame impact, non-releasing of the airbag
is not to be considered an operation incident,
the releasing speed not being reached. By e xpe ri e nce, t he spe edome ter i s not
showing correctly the impact speed, this being,
generally, smaller t han the cruising speed had
before the impact.
A vehicle equipped with driver airbag is to be
identified by the marking “Airbag” from the
steering wheel pillow and a sticker placed on the
windscre en left side.
AT T E N T I ON !
Because the UCE airbag, steering wheel
airbag and the shock sensor are containing
se nsitive components, t hese are t o be shock-
proofed during their handling.
At every windscreen replacement, the sticker
mentioning that vehicle is equipped with airbag
is to be placed on the windscreen.

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
Connect the CLIP tester to the vehicle,
the contact being set off. Set the contact on.
Block the UCE airbag: -select the menu “ Diagnostic”
- select and validate the vehicle type.
-s elect and validate the diagnostic
system “Airbag / Pre-tensioning systems”.
