    Icon10 That bloody ABS light again

    Hi guys,

    I was just wondering if someone else had this problem on their Mi16.

    Advertisement


    When the car is cold or the outside temp is really cold and I move off without letting it warm up too much, the abs light comes on.

    If I turn the motor off the ECU resets and it goes away (usually).

    Is this just a bad earth, if so where should I look to fix it?
    I know the ABS play up on the series 1 but it seems to be working fine.

    cheers

    If it ain't broke, use a 12" shifter.....that usually does the trick!!

    David,

    If you take each wheel off and look at the back of the actual hubs, you'll find a serrated wheel. Mounted with just a mm or so of clearance is the sensor (easily found by following the co-ax that aattches to it) and the way the ABS works is that the sensor (a magnet) counts the number of serrations as they pass by it. When a wheel starts to lock up, the speed of the serrations passing the sensor slows down and that is when the ABS takes over and tries to keep them all going at the same speed.
    Given the location of the sensor and the serrated wheel, they attract a lot of dirt, grome and rust as well as any grease that may fly off a front wheel due to a busted CV boot and this will affect the operation.
    The sensors can be unbolted and cleaned and the serrated wheel cleaned up and often this is where the problems with these ABS systems stems from.

    This is what an ABS sensor looks like; in this I was greasing the sides where it is held in the mount. The face is the square end pointing towards you. That is what has to be cleanes and the wheel sits directly under it when it's mounted in the car.





    Hope that is some help.
