CONTINUATION
CC.1 – CC.0
RECOMMENDATIONS
Nothing to notice
Block the computer by means of the CLIP tester (see “Blocking UCE airbag”)
Set the contact off and dismount the two attachment screws of the airbag on the steering wheel.
Check the condition of the airbag releasing lines.
Only CLIP tester is to be used for measuring the isolation in point C2 of the airbag circuit (using
cable A of the 30 pins adapter).
If value resulted is not correct, replace the control under steering wheel.
Reconnect the rotating contact of the control under steering wheel, disconnect the computer
connector and connect in its place the 30 pins adapter B40.
Only CLIP tester is to be used for measuring the resistance of the driver’s airbag releasing line,
using cable A of the 30 pins adapter.
If value resulted is not correct, check the 30 pins connector (pins 10 and 11) and replace the
front wiring if necessary.
AFTER
Connect UCE airbag and driver’s airbag then set the contact on.
INTERVENTION Erase by means of the CLIP tester the failures memorized by UCE
airbag, then turn the contact off.
Perform again a checking by means of the CLIP tester; in case of failure
absence, unblock the computer.
Destroy the airbag pillow, if you are replacing it (see “Destroying
procedure”)

AIRBAG DEFECTIVE INDICATOR CIRCUIT
PRESENT
CC.1 : short-circuit at + 12 volts
CC.0 : open circuit or short-circuit at mass
RECOMMENDATIONS
Characteristics: 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 level 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
RECOMMENDATIONS
Nothing 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 the 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 <<Help>> for this intervention).
If airbag indicator lighting is not possible, perform again the checking previously described.
Indicator on after setting 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
AFTER
Erase the failures memorized by UCE airbag, then turn the contact off.
INTERVENTION
Perform again a checking by means of the CLIP tester; in case of failure

COMPUTER CONFIGURATION
PRESENT
RECOMMENDATIONS
Characteristics: nothing to notice.
Diagnostic – Failure interpretation
The presence of this failure is corresponding 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”.
AFTER
Erase the failures memorized by UCE airbag then turn the contact off.
INTERVENTION
Perform again a checking by means of the CLIP tester; and in case of

BLOCKED COMPUTER
PRESENT
1. DEF : blocked further to a shock
2. DEF : blocked by means of CLIP tester.
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. DEF
RECOMMENDATIONS
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 situations:
- UCE airbag is new ( this one is delivered blocked)
- In 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 the contact off.
AFTER
Erase the failures memorized by UCE airbag, then turn the contact off.
INTERVENTION Perform again a checking by means of the CLIP tester; in case of
failure absence, unblock the computer.
