Hi i have a classic wrx 1995 turbo and the abs light keeps coming on and i have noticed a strange sort of whirring noise when it happens????? any ideas

 

Get your wheels off and check every thing as it should be, sensors, rotors, etc.
Nothing anyone can really say on here with out seeing/hearing/feeling the problem.

 

you will do mate, when an abs sensor goes, the car thinks one of thewheels is out of range so trys to compansate. the brakes bind, as if your scidding

all you can really do is replace the abs sensor thats damaged mate
i also have a 95 turbo. and in the middle of changing mine.
easy to do, just remember mate, when looking for sensors, the early ones are metal & not the full on plastic type. the metal casing ones are slight smaller diamitor

 

pretty much what i though with it being intermitent , bloody thins lol , cheers

 

im still yet to find out how to test which one it is.

every time i ask, no one seems to know. im changing all 4
but would be good to find out how to test the early classic ones

 

i would have thought trial and error, swap one and if its ok you have cracked it if not try another

 

its alot of hasle as with these, they dont always just come on.
you have to drive, mine come on if say going round a corner quick.

drive normal, light dont come on, but binds just before hand
there must be an easyer way to tell

 

cant the ecu codes pick up which one it is

 

dont think they do on the classics, only the engine codes.
been after this information for a couple of years now.

i changed the abs sensors a while back, but its happening again
just a ball acke changing all 4.

the newer cars are obe2 plug in and it tells you, dont think theres such thing with the early classics
