Review the circuit again:

1- The fact that you jump 30 and 87 and the Air Pump runs proves that:
* Fuse 107 is OK and Air Pump is OK.

2- The "control circuit": is fuse 31 OK?

3- Lastly, does the DME send out signal via pin labeled "X60004".

4- Also check the fuse for the "Secondary air pump valve" too.

5- Is the Secondary air pump valve working?

PS: Maybe you should try the SAS Delete and forget about this whole SAS thingy (see my other thread on ideas how to do a SAS Delete!):
