Airbag system, On Board<br />

Diagnostic (OBD)<br />

Function<br />

The Airbag Control Module -J234- is located<br />

behind the console on the tunnel. It is<br />

equipped with a DTC memory. The On<br />

Board Diagnostic (OBD) connection is<br />

located under the driver's knee bar to left of<br />

the steering wheel.<br />

The control module detects malfunctions in<br />

the airbag system and stores them in a<br />

permanent memory.<br />

Malfunctions which can be attributed to a<br />

temporary open circuit in the wiring or a<br />

loose contact, will also be stored. These<br />

malfunctions will be displayed as sporadic<br />

DTCs "SP".<br />

After the ignition is switched on, the Airbag<br />

Malfunction Indicator Lamp (MIL) -K75-<br />

comes on for about 4 seconds and then<br />

goes out again. If the lamp then flashes for a<br />

further 15 seconds this signals that the<br />

airbags or the belt tensioners are<br />

electronically blocked.<br />
