The motor on a DBW is continually...and very fast, switched from one direction to the other. How fast will depend what frequency you have set or the DBW controller itself will dictate. Probably a few thousand Hz.

SO doubtful you'll get any meaningful measurement from it with a multimeter.

And are you saying the DBW blade is not moving at all ? Ever ?

What conditions are you testing under ? engine running or off ?

Are you getting any errors ?

Is both pedal and blade position all set and calibrated correctly ? etc etc etc etc

It turned out to be a simple polarity wiring issue at the throttle, basic system tracing resolved it. Serves me right for trying to compress all the wiring into a tight timeframe!
