1995 Legacy - the ABS light came on and stayed on this morning. Also, the hydralic unit in the right front of the engine compartment is running constantly with and with-out the engine being on.

Any ideas?

Thanks!

Hi. Sounds like a faulty ABS hydraulic unit relay. There were issues with these sticking thus making the pump run constantly. There is info on endwrench.com about it.

You can unplug the ABS unit ***but be aware that this will disable it***. But it may not be working at the moment anyway.

At least that way your battery won't go dead until you figure it out.

I think there are two ABS fuses; one for the controller and one for the hydraulic unit. I think they might also run some other stuff too...

Here's the article from EndWrench I was thinknig of...
ABS Relay Sticking - Legacy, Impreza and SVX through 1996
If you encounter a case of the ABS hydraulic motor continuing to run or buzz when the ignition is off, and/or an illuminated ABS warning light and a Code 52 (faulty hydraulic motor and/or motor relay) stored in memory, follow these steps: Note: This condition may be intermittent and difficult to duplicate.

1. If the ABS hydraulic unit continues to run with the key off, confirm the trouble code, if any, and follow the diagnostic chart in the appropriate service manual.

2. Check the wiring harness to make sure it is not the source of the problem.

3. If you have determined that the ABS hydraulic control unit motor is indeed faulty, replace it with the modified relay, part number 26735AA012 (there will be a white line under the word “Japan” on the case). Always check part number supercession for any changes.

A lot of owners have had luck by just rapping on the ABS relay with a screwdriver handle, or smacking it with thier hand. Not a permanent fix, but it'll get you through until you can find a new relay.

I had the same problem as the original poster tonight. On a 95 Legacy Outback Wagon, the ABS light came on at startup, and I heard the hydraulic unit continue running 5 minutes later when I shut down. One tape on the side with a screwdriver handle shut it off. I'll look into it further this weekend. "Check the easy things first."
