ABS light comes on when it rains 850 1994

It's crazy, but I've narrowed it down to this: when it rains, I can be sure the ABS light will come on. But never when it's dry weather.

The '94-95s don't seem to have problems with the ABS Control Units like the other years.
So, would it be a sensor acting up or something else?

what is the fault code when the light comes on? if it has a problem relating to rain, maybe this will help find the culprit.

OK, I just read the codes:
2.1.3
2.1.4
1.4.1
1.4.2

Looks like both rear sensors and a brake peddle switch shorted.
Any advice from here? (repair or replace?)

I think the idea that the exposed wires may have corroded is good, and will check that out.

Thanks everybody,
Don

Could be a wheel sensor, but on my 96 it was the two wires coming from the ABS control unit to the ABS pump. The insulation was coming off and causing the unit to short out. If your insulation is cracked, the moisture could be completing the short.

Just my two cents worth.
