5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from Techline,
●for approval requests when replacing parts for which approval is mandatory,
●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 vital 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, ensure that its resistance is between 1.8 and 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 procedure, enables you to keep
track of the procedure which is 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 WARRANT RETURNS
DEPARTMENT.
IMPORTANT
Airbag and pretensioner destruction and scrapping is subject to national legislation.
