Pin Test For ACC II Saab 9000

Hi
I wanted to test the signals coming out from my ACC controller unit 4071742 on a UK 1993 9000 2.3 CSE. I previously saw a diagram with the tests to run using a multimeter but cannot seem to find the article. Does anyone have the test procedure please? I am not refferring to the Self Test on the front unit but testing the pin connectors on the rear of the unit using a meter.
I have a compressor problem, where there is no power gettting to the compressor. The compressor clutch is fine, the relays seem fine, the ACC tries to cool the car and adjusts everything including the idle, but the compressor won't cut in, so I want to see if the unit is sending the power signal out. If I directly power the compressor it all runs good. The AirCon is fully charged.
Thank You
Shane
