Do you remember what it was?
In my case supply & earth are ok, airbag module (the later type) communicates fine in another car after interchange, but in wifes car no communication to the SRS DCU (3 modules tested).
Until now (if gets dark & cold outside) I think the Pink/White wire from OBD7 to the module causes trouble. The connection from OBD-7 over C0287-16 to C0287-19 to the SRS DCU is fine, but:
~2,4Meg to GND (other car without trouble: ~180k)
~4V to GND with ignition on (other car ~11,1V)
I checked C0287 and found out, that there is a 3rd pink-white wire (C0287-17)
EDIT: Although the schematic says C0287-17 goes to the auto gearbox ecu, I have a 1.8T manual.
Otherwise: C0287-18 is not wired, although it should lead to the engine ecu. Nevermind, the KW-wires are all shorted in C0287-15..C0287-20. Will try another ecu and investigate further 2morrow.
