[Shotimes] ABS

[Carl Prochilo]

Maybe I don't understand what you mean by blink, but the normal case is that
when you start the car, the Anti-Lock light is illuminated.  The system runs
a POST (power on self test), at which time you will feel a bump in the brake
pedal.  Once the test completes, the light will turn off and the ABS system
is activated.

When my LH Rear sensor was starting to fail, I might get the light to blink
as I made a low speed turn.  Over time, the cable started to degrade more
and more to the point that once the system detected an open condition in the
circuit, it just disabled the ABS and left the Anti-Lock light on.

If you are missing a whole sensor, then the ABS system should leave the
Anti-Lock light on by failing the POST.  If that's not the case, then you
have a safety issue.
