Multimeter.
– Set of adapters and borniers for using the airbag and
pretensioner wiring harness check function on CLIP and XRBAG
tools for updates comprising the borniers listed below.
Modifying the series of new airbag ignition module connectors
entails modifying the dummy ignition module.
LOCAL MODIFICATION OF THE DUMMY IGNITION MODULE
Remove the ignition module from its red mounting and remove

5. FAULT FINDING LOG
You will always be asked for this log:
– when requesting technical assistance from Techline,
– when requesting approval before replacing parts for which approval is compulsory,
– to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions.
During work on the airbag/seat belt pretensioner systems, it is essential that you lock the computer using
the diagnostic tool to prevent any risk of accidental triggering (all the trigger lines will be disabled).
The locked mode is indicated when the instrument panel warning light comes on.
If it is impossible to connect the diagnostic tool, switch off the ignition, remove the system power supply
fuse and wait at least 2 seconds for the discharge of the reserve power capacity.
Never measure the airbag or pretensioner trigger lines with any device other than XRBAG or CLIP's "Airbag
and pretensioner wiring harness check".
Before using a dummy ignition module, check to make sure that its resistance is between 1.8 et 2.5 Ω.
During the procedure, check that the computer feed voltage does not drop below 10 V.
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools.
The FAULT FINDING LOG, which should be completed during the fault finding procedure,
ensures a record is kept of the procedure carried out. It is an essential document when
consulting the manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.
IMPORTANT
Airbag and pretensioner destruction and scrapping is subject to national legislation.

correctly connected.
Disconnect the ignition module from the passenger's rear side chest-level airbag and connect a dummy ignition
module to the ignition module connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the passenger's rear side chest-level airbag if the fault becomes stored (fault no longer declared
present).
Disconnect the 64-track computer connector and check the connections (tracks 57 and 58). Repair if necessary.
Fit the 64-track test adapter (Elé. 1717) to the airbag wiring (point C0).
The CLIP or XRBAG tool must be used to measure the resistance on the cable L. If the value obtained is
incorrect, the wiring between the computer connector and passenger rear chest-level side airbag (C0/C3) is
faulty; replace the wiring if necessary.
AFTER REPAIRReconnect the computer and the ignition module of the passenger's rear chest-level
side airbag module then switch on the ignition again. Clear the computer fault memory.
Switch off the ignition.
Carry out the check again using the diagnostic tool and if there are no faults, unlock
the computer. When replacing the airbag module, do not forget to reconnect the earth
on the new module.
Destroy the passenger rear chest-level side airbag module if it has been replaced
(tool Elé.1287).
