while I have been working on selling this car, it started acting up with the ABS light/chime problem. It has had this problem before but and the computer code always said left front hub. I replaced the hub, the pigtail, even switched hubs between fronts and was able to get it under control.
This time I decided there was some problem upstream of the pigtail. So last night I followed the wire bundle up to the ABS control module. Sure enough I found a section where the wires were laying on the transmission and evidence it was rubbing on the trans in one spot. I put the plastic wire loom holder back on the stud there and replaced the corrugated wire loom with a new piece. Presto problem fixed!
One thing I see on this police car is that the corrugated wire loom gets brittle and falls apart - mostly due to sitting there idling so many hours which eventually wrecks the plastic.
