F010 AIRBAG DEFECTIVE INDICATOR CIRCUIT
PRESENT CC.1 : short-circuit at + 12 volts
CC.0 : open circuit or short-circuit a t mass
RECOMMENDATIONSCharacteristics: the measurement of the airbag releasing lines is to
be performed only by means of the CLIP tester.
Use 30 pins adapter B40 for the intervention at the l evel of the
computer connector (the gray connector of the 30 pins adapter).
CC.1
RECOMMENDATIONS Nothing to notice
Block the computer by means of the CLIP tester (see “ Blocking UCE airbag”)
Check the condition the airbag indicator from instrument panel.
Check insulation against 12 volts between: airbag indicator pin 7 of the 30 pins connector
C0.0
RECOMMENDATIONSNothing to notice
Indicator off after setting the contact on
Block the airbag computer by means of the CLIP tester (see “ Blocking UCE airbag”)
Check the condition the airbag indicator from instrument panel.
Check continuity between: airbag indicator pin 7 of the 30 pins connector
Check the supply with 12 volts of the airbag indicator.
If the performed checking did not evidence any failure, disconnect UCE airbag and connect
instead of it t he 30 pins adapter. Check only by means of the CLIP tester the operation of the
airbag indicator from instrument panel, using the gray connector of the adapter B40.
If the airbag indicator lighting is possible by means of the CLIP tester, replace UCE airbag (see
chapter <> for this intervention).
If airbag indicator lighting is not possible, perform again the checking previously described.
Indicator on after setti ng the contact on
Block the airbag computer by means of the CLIP tester (see “ Blocking UCE airbag”)
Disconnect UCE airbag connector and check the presence of the 5 pegs that are ensuring shunt
unblocking of the 30 pins connector of UCE airbag.
Ensure insulation against mass of the route: airbag indicator pin 7 of 30 pins connector

PRESENT
RECOMMENDATIONSCharacteristics: nothing to notice.
Diagnostic – Failure interpretation
The presence of this failure is correspo nding to an incoherence between the computer configuration
and the vehicle equipping, detected by the CLIP tester.
Modify the UCE airbag configuration by means of the CLIP tester, using the control “System
elements configuration”. AFT ER Erase the failures memorized by UCE airbag then turn the contact off.

DF034 BLOCKED COMPUTER
PRESENT 1. DEF : blocked further to a shock
2. DEF : blocked by m eans of CL IP t ester.
RECOMMENDATIONS Characteristics : nothing to notice
This failure is allowing visualization of the blocking state of the airbag computer.
When present, all releasing lines are inhibited, driver’s airbag releasing being not possible.
1. DEFRECOMMENDATIONS Nothing to notice
This failure is present after airbag releasing.
It is obligatory UCE airbag replacement and of the airbag pillow after shock producing
2. DEF RECOMMENDATIONS Nothing to notice
This failure is present in the following situation s:
- UCE airbag is new ( t his one is delivered blocked)
-I n case of an intervention on the vehicle, the computer blocking control is used, by
means of CLIP tester.
Unblocking : Perform again a checking by means of CLIP tester ; in case of failure absence,
unblock the computer.
Erase the memorized failure then turn t he contact off. AFTER Erase the failures memorized by UCE airbag, then turn the contact off.
IN TERVENTION Perform again a checking by means of the CLIP tester; in case of
failure absence, unblock the computer.

Diagnostic – Help
UCE A IRB AG REPL ACEMENT
New airbag computer are delivered in blocked condition in order to avoid all risks of
undesirable releasing (all releasing lines are inhibited).
This “blocked” mode is noticed by the airbag indicator lighting from the instrument panel
when setting the contact on. In order to replace t he UCE airbag, proceed as follows:
- set the c ontact off,
- dismount the central console tunnel,
- disconnect the UCE airbag connector,
- dismount the UCE airbag attachment screws,
- mount the new UCE airbag, the arrow from UCE a irbag being oriented towards front
of the vehicle, - reconnect UCE airbag connector,
- check t he system by means of the CLIP tester,
- modify if necessary the airbag computer configuration using the control “Configuration”,
- unblock the computer only in case of a failure absence, declared by the CLIP t ester.

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) .
