Air bags and seat belt pretensioners

SPECIAL TOOLING
These systems can have fault finding carried out
using the following fault finding tools :
•
XR25
only for pretensioners and front air
bags,
•
NXR or OPTIMA 5800
for pretensioners and
front and side air bags (except self contained
side air bags).
These tools allow faults in the computer or faulty
lines in the system to be detected (see the"Fault
Finding
" section).
NOTE :
These tools have an additional function
which allows the trigger lines to be deactivated,
to prevent triggering of the pyrotechnic gas gene-
rators.
XRBAG TEST KIT (Elé. 1288)
This equipment is a specially designed tool for
testing and fault finding of air bag and seat belt
pretensioner devices.
It allows electrical measurements to be made on
the various lines of the systems (see the "Fault
finding
" section).
IMPORTANT
: no measurements may be made on
these systems using an ohmmeter or any other
electrical measuring equipment: the system may
be triggered due to the operating current of the
measuring equipment.
14328S
This bornier is connected in place of the compu-
ter.
Using the
XRBAG
, it allows all the trigger lines to
be checked, the computer supply voltage to be
measured and forces the air bag warning light on
the instrument panel to illuminate.
Terminals also allow continuity checks on the dia-
gnostic lines, on the warning light lines and on
the supply to the computer (see "Fault Finding"
section).
