Wasn't sure where to put this, so apologies if it's in the wrong place.
My '93 3.2S has a very strange ABS fault.
When starting her up the dash light goes out fine, however, when I turn hard right (mini roundabout or similar) it comes on, and will then go off when I straighten up the wheel again.
Occasionally the light decides to stay on continually after a right turn, but if I switch the ignition off then back on again it goes out immediately.
Any ideas where to start?

When the wheels straighten up again the gap is again inside the tolerances, the flux increases and the fault is cleared by the ECU.

I traced the fault to a faulty abs ecu in the boot, I swapped it for another one and the problem was cured for good.
Strange but true.
I hope this helps.
