Re: Intermittant ABS light '93 GC
Which one may look fine but be salted up? I presume you mean the
sensors and/or their connectors. In my case the big ABS module 40+pin
connector was pristine. It looked like no water or anything had ever
gotten into it.

Any of the connectors but usually it's the big connector on the ABS
computer. http://www.revbeergoggles.com/Fixes/computer-abs.jpg
It might look fine but it's probably not. The 93 ZJ drains water
from the hood right down on the top of that connector and it's
subjected to air/road stuff that makes it in past the seals around
the intake and left headlamp.
The place stuff gets into is under the connectors hood where the
wires go in. If you take the back shell off and tap it you will
probably see lots of dirt fall out. That's the side that gets
contaminated with road salt/etc and develops small current leaks
between wires. Since the ABS sensors are so sensitive, even the
smallest current leaks can cause problems.
Usually have to clean mine about once every 2-3 years.
If you take the air filter top off and remove the filter, that
spot makes a good location to set a plastic bag and clean the
connector. You don't want to use connector cleaner over paint
as it's also good paint stripper. The bag and a paper towel
catches the excess fluid/debris.
The stuff I use is TechSpray, Econoline Contact Cleaner #1622-10S
(Safe on _most_ plastics) :) Connectors are ok, soft rubber
or vinyl tape ... that's another story...
I usually pull the ABS computer fuse before working on that connector
although contact cleaner is non-conductive. If you use a brass brush
to clean the connectors make sure you vac and examine for loose bristles.
