Transporter 2016 ➤
General body repairs, interior - Edition 03.2020
♦ Remaining sensors for lateral acceleration in event of defor‐
mation of attachment points in vicinity of sensors
Additionally:
♦ All belt inertia reels with triggered belt tensioners
♦ All belt inertia reels with triggered belt tensioners
♦ Belt buckles for all belt inertia reels with triggered belt ten‐
sioners
♦ Belt adjuster (mechanical and electrical) for all belt inertia reels
with triggered belt tensioners
– If you suspect that belt tensioners or belt force limiters have
been triggered, connect a vehicle diagnostic tester .
– Under "15 - Airbag" in »Guided Fault Finding« check whether
there is a crash entry logged for the airbag control unit.
– At the same time check whether the "Resistance too high" fault
is also logged for belt tensioners and/or belt force limiters.
Triggered belt tensioners and/or belt force limiters have to
meet both conditions. "Prerequisite: The airbag control unit
has not yet been renewed".
Note
The "Resistance too high" fault can also be logged in the event
♦
of a cable break. Under normal circumstances, no crash entry
is then logged.
Depending on the crash intensity, it is possible that the belt
♦
tensioner was triggered but not the belt force limiter. In this
case, observe notes on disposal of pyrotechnic components
⇒ page 5 .
In addition, note the section: Checking seat belts
♦
⇒ page 12 .
Deployed belt force limiters can be identified by the following
♦
features:
The pin -1- and lug -3- have popped out of the belt force limiter
♦
housing on the belt inertia reel.
♦ The strap -2- is no longer vertical but is pointing diagonally
outwards.
– If parts of the belt system are removed because of an accident,
the belt system bolts must be renewed.
– In addition, the following must also be replaced if necessary
(visual check): all damaged components.
1.13 Checking airbag securing parts after an
accident
All damaged securing parts must always be renewed. It is not
permissible to bend the components back into shape or »make
them fit«.
The following components must be checked after the relevant
airbag has been triggered.
In the event of the front passenger airbag being triggered:
♦ Central tube for dash panel; it must be possible to install the
supports for the front passenger airbag and front passenger
airbag unit tension-free. Otherwise the central tube must also
be renewed.
