I have a 4x4 sapph, the abs light comes on when i start the car, which it's supposed to do i believe, then it goes off.
But sometimes when i go to drive away the ABS comes on and the brakes don't work, the pedal judders like the abs has cut in, but when i reach over 20moh, the light comes on and the brakes work ok again.
Sorry if that doesn't make much sense but has this happened to anyone else here before?

i have this to. when im braking soft the abs cuts in. but when i brake hard its ok.
a bloke told me once that it could be the wires which are connected to the hubs (spelling).

cheers

 

It's a common problem m8, could be a faulty hub sensor, bad electrical connection or a problem with the ABS unit itself.

Maybe best try someone else's ABS unit first if you can, otherwise, change sensors. I believe (really not sure on that one), that they are the same as on Granadas which may be cheaper than buying ones for a cossie (or, more easily available from a breaker's yard).
If changing sensors didn't help, you have a wiring problem.

good luck.

 

sensor if you got 1 from the breakers check it on a good system then put it on yours and swap around the 1 you take off start with the n/s/f main one that goes and the back ones are diffent

 

i should have spare ones for you when i get home!

 

Disconnect the sensor plug and check resistance with a multimeter you should not have continuity repeat as per four ,clean all four plug connections after check.

4x4's have a different ABS module Bob, I have one from BNO if you are really stuck rog!
