ABS LIGHT SHOWING ON DASHBOARD AND WHIRRING NOISE (FAN?) FROM UNDER THE BONNET SEEMS TO COME FROM ABS CONTROL UNIT, EVEN WHEN ENGINE SWITCHED OFF.

1995 Subaru Legacy • 120,000 miles

Disconnected battery overnight to avoid draining it with (possible) fan running. Stopped once battery disconnected. No other problems - braking normal, no other noises.

Could be the relay stuck on.

ABS on means it's not working. You just have normal brakes.

Thanks for that. So how do I check that it's the relay? You're talking to a non-mechanic here by the way. What's the step-by-step to check that?
