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.
