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”.

HECKING OF THE AIRBAG SYSTEM CIRCUITS.
The transmitting wiring of the airbag-releasing signal is integrated in the front wiring.
In case of an abnormality noticed on the transmitting wiring of the airbag-starting signal, this
is to be replaced a nd not repaired.
The security device can not tolerate a ny classical reparation intervention of this wiring or of
the connectors.
AT T E N T I ON !
When repositioning the new wiring, ensure that t his one is not in contact with sharpen
edges which m ay destroy it.
REMARK:
The airbag electric wires t est i s to be performed as follows: - Set the c ontact off
- Connect the CLIP tester to the vehicle
- Set t he contact on
- Block UCE airbag
- Set the c ontact off
- Disconnect the battery (-) terminal
- Dismount the central console
- Dismount the airbag attachment screws.
- Disconnect the airbag connector
- Connect the inert igniter.
- Disconnect the UCE airbag connector and connect the 30 pins adapter connector instead
of UCE airbag and the 30 pins adapter exit cables are to be connected, one by one to the CLIP

Diagnostic – Failure locating tree
Ensure t hat not CL IP tester i s the failure cause – try its communication with some ot her
vehicle UCE airbag. If CLIP tester is not the failure cause and the dialogue is not established
with no other computer of the same vehicle, it is possible that another damaged computer is
perturbing the diagnostic lines L and K.
Proceed by consecutive disconnection for damaged computer locating.
Check the battery voltage and perform the necessary interve ntions in order to obtain an
adequate vol tage, with the value between 10.5 volts and 15 volts.
Check the presence and condition of the supply fuse of UCE airbag.
Check the correct connection of the computer connector and the cables condition.
Check the computer correct supplying: -Disconnect UCE airbag then connect the 30 pins adapter B40.
- Check and ensure voltage presence be tween plugs marked mass and +DC (+ after
contact)
Check the correct supplying of the diagnostic socket: -supply + permanent at pin 16
- mass at pin 5
Check the continuity and insulation of the connection lines diagnostic socket / UCE airbag:
- plug 23 of UCE airba g pin 15 diagnostic socket (line L)
- plug 9 of UCE a irbag pin 7 di agnostic socket (line K)
If dialogue is not established after these checking, replace UCE airbag (see c hapter “UCE
airbag replacement) .
