I replaced the rear ABS sensor(again) but Ive still got constant ABS and Brake idiot lights on.I also pulled the power to reset the system,but it came back on right after flickering off.Verified that the rear ABS doesnt work by flat spotting my tires at about 15mph....didnt take much effort!
The rear ABS seems very simple,just a small set of solenoids and a few wires below the MC.Are they prone to failure?Wiring/plugs looks good.
I also noticed on the underhood fuse box theres a relay postion named "ABS yellow light".....but theres no relay and no prongs for there to be a relay,just holes in the plastic.Perhaps this relay is only used if you purchased 4 wheel ABS?

from what i read the relay is for 4 wheel ABS.my lights are still on,checked every thing even the vaccum sensor on the driver side fender well. turned out that the ground wire somked that came from the RWL abs valve on the firewall.the box that controlles the rwl shorted out but ne fuse blew,so i pulled the fuse for the box.
