Fuzpile Posted November 12, 2010 Share Posted November 12, 2010 1997 Legacy the unit is humming all the time like a motor running. It's humming at idle which I guess means all the solendoids are running like crazy looking for something. This can't be right. I had an earlier post and searched-can't find that. Real time info appreciated. Thx. Quote Link to comment Share on other sites More sharing options...

Real time info appreciated. Thx. My sons 96 legacy 2.2 had the battery die on me and then I realized there was a faint hum coming from the ABS unit (front passenger side of engine compartment) It will (should) kill your battery I disconnected the wire going to it and all is well...except no more ABS (your ABS light will come on) I would like to replace the electric part but I need to find one reasonable...especially now that winter is coming. I don;t know if it is real easy to replace this or not. maybe someone else can chime in Anyone got one for sale? Quote Link to comment Share on other sites More sharing options...
Fuzpile Posted November 12, 2010 Author Share Posted November 12, 2010 Well BG I thought my previous response went through. It didn't obviously. I should PM you because we can crack this nut. Quote Link to comment Share on other sites More sharing options...

[...] See http://www.ultimatesubaru.org/forum/showthread.php?t=116111 Is the dash ABS warning light lit? If so, codes can be retrieved that may help diagnose the problem.

The common cause is a stuck relay. See http://www.furi-dorifto.com/tech/Subaru_dox/ABSInsiderEWFall05.pdf Quote Link to comment Share on other sites More sharing options...
Fuzpile Posted November 12, 2010 Author Share Posted November 12, 2010 Thanks folks. It was kind to retreive that earlier thread for me too. Mine is unlike our other friend's problem. It doesn't drain the battery. That link may be of use to him . Noise went away for awhile and came back recently. Never an ABS light except on startup for a few secs. Thanks again for the help. I won't post again except to report the solution. Quote Link to comment Share on other sites More sharing options...
OB99W Posted November 12, 2010 Share Posted November 12, 2010 Intermittent "weirdness" with the ABS system is sometimes caused by a poor ground connection. You might want to check for corroded ground points near the ABS unit. Dirt/mud/filings on the wheel sensors or tone rings can also cause problems that come and go.

Fuzpile Posted November 12, 2010 Author Share Posted November 12, 2010 Gracias again sir. and I'll save those links. I really like this car a lot. They are so safe and agile. i notice them all over the place now. Some are beat to hell and look like nobody knows where the hood latch is. Then there are the newer ones which are cool. For every one problem mentioned here there are probably hundred if not thousands running around with no concerns to the drivers. Those of us -WHO LIVE WITHIN OUR MEANS- eventually get these gems after they've been a little screwed up. But with You and others here we have a resource that the PO's never knew. pretty neat:) Quote Link to comment Share on other sites More sharing options...
Fuzpile Posted February 13, 2011 Author Share Posted February 13, 2011 I need to clear something up which may come up as a previous thread re ABS "noise" at idle. Many more knowledgeble than myself came to another's aid and . What it is what they said the esteemed long-throw inside CV joints develop inside wear which is noticable in drive, at stop. That is, they may rattle a bit at stop because that is where the area in straight drive wears. Quote Link to comment Share on other sites More sharing options...
