tldr: airbag lamp glows on startup for 1-2 mins, and I have problems connecting a diagnostic tool.

I have a 1996 c180. Recently I removed the gaguecluster to check on the lamps. After putting it back in the airbag lamp started glowing on startup for 1-2 minutes.

I suspected that the removement of the gaguecluster induced a faultcode so I baught a diagnosis tool (iCarsoft MB V1.0) and a adapter connected at pin 1, 3, and 4.

After some trying out and even resoldering the connections to pin 1, 2, and 15, it still didn't work.

Do any of you have some advice for me, or should I seek professional help?
