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

The driver’s airbag is located in the steering
wheel pillow. The driver’s airbag is composed of: -an inflatable pillow
-a pyrotechnic gas generator with a n
igniter.
These elements can not be separated.
REMARK:
When the airbag is released, the
steering wheel cover is broken. The airbag indicator from the instrument
panel is controlling the good operation of the
driver’s airbag. REMARK:
The system is operational only after
settin g the contact on.
A vehicle equipped with driver’s airbag is
to be i dentifi ed by the inscription “Airbag”
from the steering wheel central pillow.
DISMOUNTIN G
AT T E N T ION!
It is forbidden the pyrotechnic system
handling near heating sources or open
fire because of risk of the s ystem
undesirable releasing.
OBSERVAT ION
Before dism ounting the airbag pillow,
bloc the UCE airbag by means of the CLIP
tester (see “Blocking UCE airbag”. When
this function i s active, al l t ransmitting lines
of the releasing signal are inhibited. The
airbag indicator from the instrument panel
is on.
IMP ORTANT:
Before di smounting the steering wheel, i t
is necessary the di sconnecting of t he airbag
connector (1). OBSERVAT ION
The driver’s airbag pillow is provided with
a connector that is short-circui ting after
disconne ctin g the wiring conn ector,
avoiding in this way all undesi rable
r eleasing.
REMARK:
After releasing, UCE airbag is
automatically blocking all releasing lines.
DISMOUNTING OF THE DRIVER’S AIRBAG
Set the contact off
Dismount the two attachment screws located
under steering wheel, attaching the airbag pillow. Disconnect the airbag connector.
IMP ORTANT:
After airbag pillow replacement
considered discard bu t not tripped, its
destroying procedure is to be imposed (see
chapter “Destroying procedure”).
R EMOU NT I NG
Check if th e airba g indicator fro m the
instrument panel is on with the contact set on. Conne c t the i ne rt i gni ter t o the airba g

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.

30 PINS ADAPTER – B40
AT T E N T I O N !
In case of an intervention at the airbag
sy stem, it is obligatory t he UCE airbag
blocking by means of the CLIP tester in
order to avoid undesirable releasing (al l
relea sin g lines are inhibited). This
operation mode is signaled by the airbag
indicator lighting from the instrument
panel.
The adapter B40 i s to be connected on
line instead of UCE airbag.
This i s allowing, by m eans of the CLIP
tester, the control of all system lines, the
measurement of the UCE airbag supply
voltage a nd the compulsion of the airbag
indicator lighting from the instrument panel.
The termin als are allowing in the same time,
the perform i ng of t he c he cking of t he

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 ¿.
〈〈〈〈Ensure that during intervention, the computer supply voltage is not less than
10 V.
