Iain, forgive me but I'm not sure what you mean by "tails" and therefore how you've wired your test equipment.

The ABS sensors are active devices so need to be connected to the ECU at all times. Are you therefore using a "break out" loom in series with the sensor and ECU which enables you to make measurements whilst maintaining full connection?
