do you know what sort of reading they should be
what if they all read but all different readings
totally to confuse the issue as its going to be a pain in the arse as its 4wd with 1 jack and no axle stands at the minute
The ABS sensors work on the principle of magnetic induction. The sensor consists of a magnet mounted in close proximity to a toothed "reference ring" that spins at wheel speed causing a "sine wave" (a low-voltage rhythmic pulse) to be generated by the magnet. Your picking up this pulse on the multimeter
Other than that yes the multimeter will read something (which is all you need to know to see if its working) it will either read or not.
As for the 4x4 thing take it out of gear to spin the wheels
