3 phase pumps are easily evaluated in Picoscope using XY mode.

Thanks for the Info

[@omarmargi7142]

which phase gets power to prime when opening door or unlocking car?

[@AutolandScientechUSACedarPark]

All three are controlled to activate the pump. See the start up waveform in the video.

Does anyone know if the fpc will function without the crash data signal hooked up?

[@AutolandScientechUSACedarPark]

No, it will not.
