Looking for some ideas/help as to why my ABS light is flashing. It's on in Park or Neutral, then flashes constantly when in gear. Need some input as to where to start with this, other than black tape over light (I already know how to do that).

Anti-lock still seems to be working, I tried to lock 'em up in snow last night, felt like the front was working anyway, but the rear really didn't seem to get wild either. I haven't looked into the sensor on the rear yet, thought that's where I'd probably start. I've got a firm pedal, no pulling when I stop.

Looks like a Kelsey-Hayes 3 channel system.


Thanks for any help.

Check all the fuses and relays, but take the connector off the rear end housing and clean it.
