1998 S70 T5 ABS relay location?

After an extensive search of this site for existing posts on my problem I now need to ask: Where is the ABS relay located? I have the following code; ABS-443 (pump motor electrical or Mechanical fault) Many posts on the subject refer to a ABS relay, I either can't find it or have a misunderstanding of what it is. I own 3 similar cars so I often swap suspected problem parts between them to help diagnose problems. If the problem transfers to the other car I have found the culprit. I have swapped the ABS control module between 2 cars with out change, so have eliminated that from the possibilities. I next want to try swapping the relay to either confirm or eliminate it as my problem.

Thanks CN90 I had read through that thread before. In it is mentioned a relay and the control module. I have experience with the control module and don't believe that to be the problem, but I don't know what is being referred to when it mentions replacing the relay.

There is no relay, the motor control is a solid state circuit built into the module. The 443 code is one of the telltale codes of broken solder joints on the circuit board.

So since I have eliminated that possibility by switching the module with another car with no change to either car, I am beginning to think that I need a new pump.

Ohm out the pump or apply 12 volts to it. It's a lot easier than replacing it.

On my 1997 850 T5, removal of fuse 9 generates ABS-443 (if removed by itself, without removing any of the other two ABS fuses).
