Did you do the test for each terminal using 6v power source? My backup Haynes says; "If servo vibrates slightly during these tests, it's OK. If not replace." "...note whether there's any vibration..."

I've never done the test but it looks like a short (slight) vibration is a pass. Did you test TPS?
