Hi/

It appears that my abs is always on when I brake. I would assume this is down to a faulty sensor. Is it possible to remove each sensor and test i.e drive up the road to see which one is at fault? Or is there another way

Thanks,
Jamie

Hi Jamie
What symptoms do you have and what age is the car.  Is the ABS light on?

Hi/

1998 CDX 71,000 miles. Juddering upon braking. ABS light is not on.

Sounds more likely to be warped discs.

Or buggered front wishbone bushes......

it happened all of a sudden. the car was fine then not used for a two weeks (due to heavy snow), then when i used it the juddering started.

I'm pretty sure that due to the way ABS systems have to be fail-safe, this is actually impossible.  "Safe" in this context  meaning "Does nothing to interfere with the normal braking system"
So if there is any fault detected by its 'selfchecking' it simply does nothing, as if it weren't fitted at all.

So i have three options abs faulty, wishbone bushes or discs.

I assume then that i can take the sensors out and the abs (if it is this) would not judder, as its not sensing. With the wishbone i would thought this would happen all the time? I will check the discs but it seems strange that it can happen straight away, like flicking a switch i thought you might see some deterioration

Does the ABS light come on with the ignition, and then go out again?
If so I think you can rule out ABS problems.

There's a fuse to the abs in the fusebox. Pull it out and abs is of. Then you can se if the problem is still there.

Thanks Monza GSE. I like that one.

also, if ABS is running (i.e. modulating), you'll be able to hear the recirculation pump running.
