'90 Legacy ABS light problem

[tcarney]

Hope someone can assist: our 90 Legacy with 140,00 kilometres has the ABS
warning light on. My shade tree mechanic (very good, but not a Subaru
specialist) finds a code reading #9. According to his 'puter, this can mean
either the ABS relay (relatively cheap, I presume), or it can mean a new
ABS pump/motor.

My mechanic, an honest bloke, says it can take hours of diagnostics
(hence, expense) to determine which it is: Anyone have experience with this?
Are the relays prone to malfunction more than the pumps? I hate to just
guess, but I am inclining toward putting in a new relay and see whether that
fixes it or not...If not, then I might scout around for a used ABS pump....
Thanks for your advice if possible.

Have a competent mechanic check the wiring harness. Next I would guess that
the system had been improperly bled...this can really foul up an ABS system.
Of course if you know someone bled the system ask them how and if they
didn't follow the correct procedure then I guess they owe you a repair. TG
