Bosch ABS sensor

Hi there! Been trying to work out how to use bosch abs M5 sensors to use directly as speed sensors, I belive the pinout should be just digital signal/digital gnd but i cant get any reading at all.

Tried using a m18 sensor and it gets frequency, and it wont change with polarity it seems.
Its configured as VR sensor (tried Hall aswell) and no pullup (tried 1k pulldown just incase)

Thanks in advance!

they are MR sensors nor VR, you need 12V and a signal with a pulldown.

Like Greg said, they are called MR or 2-wire Hall sensors.

Check out the manual for the WheelSpeedToCAN module.
Everything about those sensors is described in there.
