Airbag system, On Board
Diagnostic (OBD)
Function
The Airbag Control Module -J234- is located
behind the console on the tunnel. It is
equipped with a DTC memory. The On
Board Diagnostic (OBD) connection is
located under the driver's knee bar to left of
the steering wheel.
The control module detects malfunctions in
the airbag system and stores them in a
permanent memory.
Malfunctions which can be attributed to a
temporary open circuit in the wiring or a
loose contact, will also be stored. These
malfunctions will be displayed as sporadic
DTCs "SP".
After the ignition is switched on, the Airbag
Malfunction Indicator Lamp (MIL) -K75-
comes on for about 4 seconds and then
goes out again. If the lamp then flashes for a
further 15 seconds this signals that the
airbags or the belt tensioners are
electronically blocked.
