Odds are the ABS computer connector is full of junk and needs a good cleaning.

Take the connector off, take the backshell off, spray it with TechClean or
similar contact cleaner, pack the connectors with dielectric grease then slap
it back together.

Watch the contact cleaner as it will eat paint. I find it easier to work over
the air filter box and use a plastic bag and paper towel to collect debris.

Problem with the ABS system, if the ABS light stays on then the ABS function
is disbled but the brakes will still work normally. Could be a wheel sensor
(cheap) or the ABS control unit (not cheap). If you've had all that rain I'd
suspect a wheel sensor plug got some water in it.

Re: ABS light ON???
 

It can be one of two things, and is probably one or more speed sensor on the
wheels, but could be the valve body that routes the brake fluid to the
wheels.

It depends on when the ABS light comes on. If you start the car and the
light comes on with the key, but goes out after a few seconds, then comes
again BEFORE you start moving, this normally means one of the selonoids in
the valve body is toast. On my BMW, the valve body is about $1000. If the
light comes on with the key then goes out, then comes on again AFTER you are
moving, then you have lost a speed sensor in one of the wheels.

Be wary of the speed sensors because they are susceptible to poor electrical
connection, but are often replaced at a cost of about $100 each - again,
pricing from my BMW - when they often will work again if they are just
unplugged and plugged back in. Perhaps a shot of contact cleaner while they
are unplugged ...
