abs failure

[Anonymous]

Anyone had abs failure yet. Wife went to change 1st set of tyres(20K), soon as she fired up abs warning light was on! Fitters said 'nothing we've done', went to Toyota dealer for diagnostic check which pointed to abs accumulator failure, which is located in the front under the plastic cover. New part £600+ vat + fitting. Expensive tyres! Obviously just out of warranty so Toyota aren't interested (no surprise there). Is it time to visit the breakers or has anyone had experience of this?

Also brakes have started rumbling now as well (like pads are badly worn but they're not).

Very odd.

could just be the sensor got a little dirty? have toyota said you definatly need a new part?

SteveJ is the expert on this one as he had an ABS failure too, although I believe his was never fixed properly - he may be able to assist with some advice though.

My ABS failure was somewhat more serious than that - the error light never came on but the rear wheels locked whilst the ABS released the brakes on the front wheels - not good @ 70mph with a stationary vehicle 30 yards in front of you  s:? :? s:?

Toyota eventualy replaced the vehicle (after a 6 month battle) as the fault existed when the car was delivered.

Given the timing of your problem, I would suspect the wire has been damaged to one of the ABS sensors - almost certainly by the tyre fitters.

MrT will have just checked the error code from the OBDII port and probably not done any investigation. First thing to do is remove all of the wheels in turn and check there is no damage to the ABS sensor wire. After that I would suggest you head off to an ABS specialist (avoid Mr T as they will charge like a wounded bull)

Nasty, at least our car isn't trying to kill us. I have actually already tried
what you have just mentioned as this is what i thought of first myself after bitter experience with my old alfa 3.0 when the dealer said their equipment will find the fault. It didn't, they then proceeded to just replace parts until it worked. I'm sure toyota uses the same theory.
The car has been to an ABS specialist to test the wires to the sensors and these (unfortunately!) checked ok and i have had all the wheels off for a visual inspection and couldn't spot anything either. Specialist said the abs system has its own ecu which he could send off and have checked (for  a price). All seems a bit extreme, the only wory now is if i get a accumulator from a breakers will it be compatible with our car's abs ecu i wonder?
My head hurts.
