Testing ABS Pump Module

[Tcrate]

I have a 1998 M3 and my AST and ABS light are on. I took it to a mechanic and he tried to pull codes.... He could not connect and told me the issue was with the pump module. I pulled it out of the car tonight and was expecting a different setup on the solenoid wiring. I am not sure where to go now. I would like to find someone who can run a diagnosis on this for me while it is out. Does such a shop or service exist?

Thanks
Thom
