Self-diagnosis of airbag system

Description of system

Airbag system comprises:
♦ Airbag control units
♦ Side crash sensor
♦ Driver airbag
♦ Passenger airbag
♦ Driver and passenger side airbag
♦ Mechanically ignited seat belt tensioner for
driver and passenger seat belts
♦ Switch for front passenger airbags (special
equipment vehicles MY03 ®)
The described airbag system consists of the
actuators, driver airbag, passenger airbag, driver
and passenger side airbags and two front seat
belt tensioners.
These are directly ignited by the airbag control
unit (J234) in the event of a crash as soon as
the given activation criteria are exceeded.
The belt tensioners are ignited independently
of the signal from the airbag control unit.
It is possible to re-activate or deactivate the front
passenger airbag using the self-diagnosis
⇒ page 01-15.10.
If the front passenger airbag unit is deactivated,
a fault relating to erasing airbag unit is stored in
the fault memory and after the airbag unit is sub-
sequently re-activated, it is erased from the fault
memory (only for vehicles which do not have a
switch for the front passenger airbag).
The switching on and off operations are underta-
ken by means of the switch for the front passen-
ger airbag if the vehicle is fitted with such a switch.
When igniting the driver and front passenger
front airbag, the fault „crash data stored" is ente-
red into the fault memory and the airbag control
unit must be replaced with a new original part.
If the control unit detects a side collision, it ig-
nites the side airbag on the crash side. The fault
„crash data of driver side airbag stored" or „crash
data of front passenger side airbag stored" is
entered in the fault memory. These data can be
erased 3x at the most, after which the control
unit must be replaced with a new original part
(valid for vehicles 08.00 ®).
For vehicles ® 07.00 these data cannot be era-
sed, the control must be replaced with a new
original part.
Code the new control unit when it is put into
service ⇒ page 01-11.
