airbag control unit not speaking to Alfadiag

I have a 2000 Spider with the usual "airbag light on" problem. Underseat
connections have been cleaned with magic spray and should now be ok.
I have the AlfaDiag software / interface and it works perfectly with the
ECU, but switch from pin 7 to pin 3 for the Airbag controller and it won't
communicate.
AlfaDiag were very helpful but can't suggest anything more to try, and as
the car is a German import I'm wondering if there is a different protocol
used by our teutonic friends.
The Airbag controller is a TRW 202862-112. Anyone had difficulties with
airbag controllers?
Cheers,
Rod

I have this problem, too.

It's caused by either an internal airbag ECU failure or a non-clearable
without replacing a component fail.

I'm just going to take the bulb out.
