Unhappy ABS light

Ok. So after getting stuck in some snow/slush/ice mix the other day on my first true off road drive i notice on the ride back that the ABS light was on. I read somewhere that it could be just tire spinning that causes a false code. If it is just a false code, will it simply reset it self or what would i have to do? Also whats else could it be?

P.S. Ill get some video of it up later.

didn't get many answers did ya. Anyway I have the same problem. My dash has gone ABS light happy. If i spin a tire it comes on, if i slide just a foot with one wheel it comes on and if it hasn't been on a while it will just turn on for no reason. I'm planning on just pulling the fuse out because i hate abs anyway. I was coming down a steep trail of loose rock and the abs engauged and i went flying down the hill almost over a cliff out of control because the brakes just wouldn't grab. i went down the hill later with the abs light on just fine since the abs was not working. i feel abs is only for tailgaters on the highway so they don't hit the car in front of them. don't tailgate and you don't have to suddenly hit breaks so hard all the time.
but back to the issue. An ideas why the ABS light has been so sensitve and If i pull the fuse out will the abs light on the dash go out or just stay on.

Rule for ABS when coming down a hill, put the car in neutral, otherwise the ABS, the driveline and physics all fight eachother. That usually solves the down hill issue.

As far as the light, why doesn anyone ever bother to do diagnositcs on these things, its not that hard. Porcupine has a good write up on it.

As far as what the problem is, its usually a bad wheel sensor. The sensors are cylinder shaped. Slight erosion of the sensor will cause the sensor to send a fault code to the computer.

PS mud, deep water and dirt can cause the light to come on temporarily, though i dont see this issue often with soobies, i do with other cars and it is considered normal. It is also possible you broke a wheel speed sensor wire.

Yes I think on that era with external type tone ring sometimes mud or ice would get into the tone ring and mess things up temporarily. Here's my abs-2e info with info borrowed from various sources for reading out the codes, but you might have a later system. If you search abs at www.endwrench.com there is an article that tells how to read the codes from all subaru abs systems and how to tell which system you have.

AH yes, its a common problem as they age. One of the two relays on the ABS pump are stuck. Get them from a junkyard, as the dealer wants an insane amount of money for one.

Ok i pulled up that section of the manual. There are supposed to be two relays under the black cover. One is the valve relay, the other is the hydraulic pump relay.

Send me your email and ill email you the section.
