   my abs light has just appeared in my saxo, i look it to an wide open space, (runway) and at 60mph stood on the brakes, the left wheel locked and the right side did its abs thing, the car started to spin. do i need a new pump or is it just a clean the sensor job? i know it sounds like a dangerous way of testing the abs but on my old alfa it just used to stay on even when it worked. cheers

   just try cleaning it first
   
   then if that doesnt work replace the sensor

   As above.
   
   Forgot how much they are, but they aren't that expensive to replace.

   Light came on mine today.
   
   Stand on the brakes and it tries to turn/spin to the left towards the kerb.
   
   So I assume its the left side but cant tell ifs its front or back
   
   Didnt realise they were that expensive either

   Take it yours is a vts
   
   if so yer. I was thinking it could be the rear as mine feels like it wants to spin kind of like the handbrake is on if you hammer on the brakes once it slows to below 10-20mph

   if ABS light is on the abs is deactivated as a safety measure, so your experiences are just from individual tyre grip, camber of the road, weight on each wheel etc etc. needs to be put on diagnostics £10 ish will give you a 100% accurate conclusion on which sensor needs cleaning or replacing.

   So it definatly deactivates them all?
   
   
   Might have to to give it ago in an empty open car park where its 100% flat. Might been I have a sticky caliper too

    yup, its a safety measure, could you imagine the result if two sensors on the left hand side failed under heavy breaking in the wet the car would swerve drastically to the right and most likley spin.

    if i remember right diagnostics only tells you if its front or rear but not which side... i may be wrong... but i know both rear are same and both front are same there is no o/s n/s variation....

    There is a guide on here somewhere that explains how to test the sensors with a multimeter from the multiplug that sits on top of the ABS pump. have a search or someone may be able to dig it out for you.
    
    My light was on and i had no clue which sensor it was. Used the guide and found out it was the N/S rear sensor. I replaced the sensor and the light went off.

    Nah it does say which sensor it is whether its N/s or o/s , front or rear

    Yeah it was on 106 owners, somewhere lol.

    I've had a similar in the past on my saxo, there should be an orange wire/plug under the drivers seat just unplug it and re plug it in and should go off (the light)
    
    Hope this helps.
    
    Regards

    How to find out what sensor is goosed.
    
    They work using magnetic fields, so I can't see cleaning up a broken sensor making any difference.

    I think you are refering to airbag lights
    
    
    Cheers for the link Lee
    
    
    How would you go about checking it with a multimeter. ie put a pin on each one but what reading would you be looking for?
    
    Im a thicko when it comes to electronics

    you need to measure the resistance of the pins, you should be reading about 1100 Ohms on the correct pins, you need to find the pic on 106 owners to know which pins.

    Yip, the diagram in that link shows the two pins for each sensor. Check the resistance across each one - as Jordysport has said, roughly 1100 ohms means the sensor is fine, my broken one was showing 0 ohms.

    Just a note, i found it was different on Mk1's the pin arrangement, (1998 VTS)

    my cars gay as its a mk2 but one of the very first so still has an array of mk1 parts on it so it will be a suprise
