Brake switch failure will need a reset of the ecu,dont go wasting time in breakers yards - get someone to read the codes.

i wouldnt bother tryin to remove a sensor its more than likely seized into the hub so unless you know its faulty id leave well alone.
the fault codes in abs are pretty accurate so my advise is to get your codes read, what will it cost you- 1/2hour labour at dealer and if its somethin simple theyll probs do it part of the process,
theres not a lot you can do without that code,
posible faults,
brake switch
abs sensor or curcuit fault
air gap too big or small
ecu ground reference fault
wires to hdc switch faulty
there are lots that can go wrong so a code to pinpoint it would help you no end

As LR Guy says abs fault codes are worth reading - even I still use Testbook as first choice with abs.The passive sensors on early F/L's are generally reliable,so unless a wheel bearing has developed play I would put my money elsewhere.Testbook,Rovacom,Autologic and Auto diagnos diagnostic computers should all be capable of finding what is wrong.
If the Ecu is registering intermittent faults on wheel sensor inputs I use a Pico Oscilliscope to monitor the sensor waveforms - often it is not necessary to go to these lengths,but the hall effect sensors on later F/L's are expensive and I dont like telling people that is what they need then it doesnt work.
Correct diagnosis is the way to go - not just throwing parts at it.

Sarky sodming said:But do the fault codes inhibit the abs? mondo ya really impressed me wiv yer knowledge mate [hall effect and all that] yer a bit off a dark horse,[full respect]. . .
But yer like the other lads say twill save a lot of hasstle to go the testbook route and pinpoint it
LR should do one free when yer buy a new motor
