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”.

In case of an i nt e r vention on the
vehicle (on exhaust, carriage body, etc),
block the UCE airbag by means of the
CL IP t e st er, wai t for 2 se c onds aft e r
s etting t he contact off (necessary time for
automatic di scharge of the UCE airbag),
then you may use hammers or shock

which may be generating magnetic field,
is not to be mounted near UCE airbag.
UCE AIR BAG DISMOUNTING
Set the contact off. Disconnect the battery

Dismount the UCE airbag connector.
Dismount the UCE airbag attachment screws

AIRBAG SYSTEM CONFIGURATION
Because the vehicle is e quipped only the

configuration only “with driver’s airbag”.
In case UCE airbag configuration does not
match with the vehicle equipping, the airbag
indicator will remain lighted.

In the case of the UCE airbag configuration, the

remaining lighted because new UCE airbag are
delivered in blocked state. -S elect mode “ Control”, select mode “

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.

IMPORTANT
After remounting, che ck the system operation, by means of the CLIP tester. If
everything is correct, unblock UCE airbag (see “Unblocking UCE airbag”). If it is not
correct, see chapter “Diagnostic. Check if t he airbag i ndicator is l ighted when setting
contact on, it is remaining lighted for 3 seconds, then it is turning off and is remaining
off.
OBSERVAT ION:
UCE airbag may accept up to 4 airbag releasing (some elements are loosing their
n ominal characteristics). It is not necessary the systematic replacement after each airbag
r eleasing.
REMARK :
The driver airbag – new item number- is provided with a self-adhesive protective foil
stacked over the airbag connector. Unstacking of t he protection foi l is to be done
ONLY in the moment of m ounting.

In case of an intervention at the airbag

order to avoid undesirable releasing (al l

operation mode is signaled by the airbag

This i s allowing, by m eans of the CLIP

APPLICATION CONDITIONS OF THE CHECKING DEFINED
AT DIAGNOSTIC
Each failure is interpreted for a specific memorizing type (present failure, memorized failure,
memorized or present failure).
The defined checking for each failure tracing is not to be applied unless the failure is interpreted
for the failure type declared by the CLIP tester.
If a failure is not interpreted in diagnostic or it is declared “present”, the diagnostic application
when the failure is only “memorized” will not allow the location of the memorizing origin of that
failure.
In this case, only a wiring and respective element connector checking must be performed (it
is recommended the wiring movement in order to try the passing visualization from state
“memorized failure” to state “present failure”).
If a failure is interpreted when it is declared “memorized”, the confirmation conditions of the
failure real presence (and the necessity of diagnostic application) are to be found at
”Recommendations” or at the beginning of the failure interpretation.
REMARK:
Before releasing diagnostic, the cont act must be off.
AT T E N T I O N !
Before any intervention at t he airbag system, i t i s obligatory t he UCE airbag blocking
by means of the CLIP tester, using the control “Computer blocking”. The confirmation
of this cont rol perform ing will be visual ized by permane nt lighting of the airbag
indicator from instrument panel and t he releasing line will be blocked, av oiding i n
this way the undesirable releasing of t he airbag during the intervention.
AT T E N T I O N !
〈〈〈〈If
the intervention is taking place after the vehicle has suffered a collision followed
by the driver’s airbag releasing, UCE airbag blocking is possible only after performing
its unblocking control performing.
〈〈 〈〈Further to a shock causing the airbag releasing, the erasing of the memorized
failures it is possible only after dat a reading from “Imp act context”, followed by
“Computer unblocking” control.
〈〈 〈〈The electrical measurements on the airbag releasing l ine are t o be pe rformed
only by using the function “ Airbag beam t ests” of the CL IP tester. It is strictly forbidden
the use in this purpose of the ohmmeter type measurement devices.
〈〈 〈〈Before using the inert igniter, check that its resistance is between 1.8 – 2.5 ¿.
