lytnin88 Posted December 18, 2005 Share Posted December 18, 2005 I was looking around the under side of my '03 Forester today, and I noticed a small-diameter hose going to each of the front wheels. (Disc brakes in the front.) It wasn't the brake fluid line, which is a larger diameter hose. Anyone know what this hose is for? Quote Link to comment Share on other sites More sharing options...
Andyjo Posted December 18, 2005 Share Posted December 18, 2005 ABS (Anti-lock Brakes) cable? Quote Link to comment Share on other sites More sharing options...
nipper Posted December 18, 2005 Share Posted December 18, 2005 thats not a hose thats an electrical cable, its for the ABS sensors nipper Quote Link to comment Share on other sites More sharing options...
Gnuman Posted December 18, 2005 Share Posted December 18, 2005 that is not a dumb question. Actually there is no such thing as a dumb question, except the one you did not ask. so ask away, if you have any questions about your Forester. We will be glad to answer them. Oh, and that hose is actually a signal cable from the ABS sensor to tell the ABS computer whether the wheel is turning. It is large because they try to protect that wire as best they can, as no signal from that cable tells the the computer that the wheel is not turning, and it would disable that brake. . .

lytnin88 Posted December 19, 2005 Author Share Posted December 19, 2005 Thanks, Gnuman. So, where is the ABS computer? Is it that rectangular black box mounted back by the gas tank? Quote Link to comment Share on other sites More sharing options...
OB99W Posted December 19, 2005 Share Posted December 19, 2005 [...]So, where is the ABS computer?[...] As far as I know, since about '98 the ABS ECU (Electronic Control Unit) has been integrated with the hydraulic control. Look for a unit with four brake lines (steel tubing) coming out of it; on my '99 OBW, it's near the front right (passenger side) of the engine compartment. EDIT: Found this, might be interesting - http://endwrench.com/images/pdfs/ABS.pdf By the way, if an ABS wheel speed sensor cable gets damaged to the point that either its resistance or the signal from it changes enough from "normal", usually the ABS unit disables, signified by the dash ABS lamp being lit. With the Bosch system, you'll still have normal braking function, just no anti-lock. --OB99W Quote Link to comment Share on other sites More sharing options...
Andyjo Posted December 19, 2005 Share Posted December 19, 2005 good link! very helpful as for the box behind your gas tank, i believe that's the carbon canister... Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted December 19, 2005 Share Posted December 19, 2005 Thanks, Gnuman. So, where is the ABS computer? Is it that rectangular black box mounted back by the gas tank? The big "checkered" black box under the gas tank is the EVAP canister, it holds fuel vapors until the engine is at a certain perameter then it burns the vapors to keep from them being vented into the atmo.

seattlelegacy Posted December 19, 2005 Share Posted December 19, 2005 There's a weird metal container behind the passenger rear wheel well on my 93 legacy wagon. Its not black or checkered, but bare metal. What the heck is it? I found it when trying to replace my speakers (it actually gets in the way of the new speakers, so I'm going to have to find different ones.... ) http://bbs.legacycentral.org/viewforum.php?f=19&sid=5e0c4e16328b6a0ee7fdebacbe8bfbf0 Jordan Quote Link to comment Share on other sites More sharing options...
nipper Posted December 19, 2005 Share Posted December 19, 2005 Could be fuel seperator, some cars used that along with the Charcoal canister to catch fumes. Is it square in shape? Then thats what it is, whats it purpose is in life and how it works, your on your own nipper Quote Link to comment Share on other sites More sharing options...
