ABS fault light intermittently flashing - 605

    For a few weeks the ABS light on the dashboard has been flashing
    intermittently, but a few days ago came on and now won't go out. The car
    brakes perfectly ok but I assume the ABS doesn't work, but haven't found
    that out yet.
    Can anyone offer any ideas? I initially suspected a bad connection but have
    no idea where to look for the appropriate electronics. Any help
    appreciated.

    Wheel sensors are often the cause of this problem. replacing each sensor in
    turn with a resistor 500 -1000 ohms and seeing when the light goes out might
    help you locate which wheel.

  3. Hi Mike

    For a Bendix system, the wheel sensors' resistance should be 1000-1400 ohms.
    You can measure the sensors by unplugging the connection to the wiring
    harness. The front sensors gap is adjustable, the rear sensors' is not
    adjustable.
    As Bob said, the wheel sensors are the most likely source of your trouble.
    Note that the ABS ECU stores errors and the codes can be read.
    If the sensors are OK, you might try disconnecting the battery for about 15
    minutes, to reset the ECU. If the error resurfaces, get someone to read the
    codes!

    On a 405 my first action was to pull off and then reconnect one by one
    the connections at the unit inside the engine bay on the driver's side
    wing. This cured it. Wherever the unit is I would try the simplest
    option first...
