whitetm Posted April 7, 2012 Share Posted April 7, 2012 I have a 1996 Subaru Impreza Outback, the wire loom that has a black connector and 2 black wire terminals. the black connector it self has 3 wires in it and the colors are 1 blue, 1 blue/green, 1 white. the wire location in the plug are the blue is #1, white #2 and the blue/green #4. There are no wires in #3 and #6 positions, does anybody have a wiring diagram that can verify this configuration? the black plug is referred to as a B-82 plug from what i have. but the manual i have refers the color of wires to be 1 orange/white and a light-green/white. so i don't know if the manual is really the proper one for this car. I also noticed that fuse # 18 keeps blowing, I even disconnected the plugs that go to the ABS control/pump and the fuse still blows. Any ideas on that one?

idosubaru Posted April 7, 2012 Share Posted April 7, 2012 the fuse blows when? when you install it? when you turn the car on? when you use the brakes? something else??? unplug ABS controller and see if it blows? unplug all the ABS sensors and see if it blows?

It bows as soon as the key is turned on. It even blew after the abs plugs were removed from the whole control unit/pump. Is the pump and control unit one piece? right side of engine compartment? The light stays on constantly. Link to comment Share on other sites More sharing options...
idosubaru Posted April 7, 2012 Share Posted April 7, 2012 weird. have you tried disconnecting all the ABS sensors? can't imagine that would do it but it's easy to try. i'd be looking into a wiring diagram to see all the components and such and start disconnecting everything.

Any idea about the proper diagnostic connector? the one the repair manual that i have refers to the 6 pin connector and use the #3 and #6 termals, but there are no wires plugged into the #3 and #6 holes.

Fairtax4me Posted April 7, 2012 Share Posted April 7, 2012 Connector B82 appears to be for the Door Lock Timer. Fuse 18 is power for the ABS control module which IIRC is under the radio in the dash. It also provides power for the Cruise Control module, and main cruise switch. Check Here for the Factory Service Manual for that car. Download pt2. The first link is for RHD cars and all of the wiring is different. http://bustedfingermotorsports.com/forums/viewtopic.php?f=18&t=170&sid=e5ead9416ece08f7a3f07a35dd7a35f7 Link to comment Share on other sites More sharing options...
Gloyale Posted April 7, 2012 Share Posted April 7, 2012 Fuse 18 supply's power to the Cruise switch, and the cruise computer, as well as powering a portion of the ABS pump. It's a Blue (L on diagrams) wire to all of them. Try disconnecting the Cruise main switch. check fuse. Still blows? disconnect the cruise computer. If it still blows, there is a short somewhere on that wire. My book also says Or/w and Lg/W colors for the diag. connectors. Is your connector shaped like this? 1 - - 2 3 4 5 6 Link to comment Share on other sites More sharing options...

The plug is shaped the same as you illistrated, but the wires are 1 blue, 1 blue/green, 1 white. the wire location in the plug are the blue is #1, white #2 and the blue/green #4 and the 2 grounding terminals come out of the same wire loom as the black plug as well.

Gloyale Posted April 8, 2012 Share Posted April 8, 2012 OK.....I think we may be looking at wrong diagrams. 96 legacy not impreza. Checking impreza manuals now.... It seems fuse 18 sends power to the ABS "G sensor" and "ABS module" seperate from the hydraulic pump.Still a Blue(L) wire. It actually doesn't directly power the pump. Pump power comes out of the ABS module. Also, I think the test leads and connector you found are for the Trans Computer. Looking up unit locations and test connector locations now.

Gloyale Posted April 8, 2012 Share Posted April 8, 2012 Also, the wiring for the cruise is still there, even if you don't have it. So maybe check the loctaions where the cruise master switch, and cruise computer would be mounted.....maybe an unused connector got wedged in somewhere in the dash and is shorting out?

Gloyale Posted April 8, 2012 Share Posted April 8, 2012 Check connector for that model ABS is actually a 2 prong, black connector. You can use those ground probes you found though, and ground terminal "L" to output codes. Although, if you can't keep a fuse in it, probably won't get a code.

Fairtax4me Posted April 8, 2012 Share Posted April 8, 2012 Gloyale did you find out where the ABS control module is? I dug and dug but never found the chart that showed where it actually is. Unplugging the connector at the module could rule it out as the source of the short. You can check for continuity to ground from that connector. If you get no evidence of shorting to ground from there, the module is likely shorted internally. Link to comment Share on other sites More sharing options...

I did find the chart but it's not a great illustration. Chart is in the supplementals section. The G sensor is on the passenger side of engine bay, mounted low to the inner side of the strut tower, down low. Link to comment Share on other sites More sharing options...

whitetm Posted April 8, 2012 Author Share Posted April 8, 2012 Fairtax3me gave me a link to get another service manual to look at. I did see the 2 wire data connector in that manual withe the same wire color code as mine does. My question would be, which wire of the data connector would be connected to the grd terminal to get the abs codes? The wire colors in the black data connector are gy and wr.

Fairtax4me Posted April 8, 2012 Share Posted April 8, 2012 Dunno about the test plug but as Gloyale said earlier I don't think you're going to get anything if the fuse for the module keeps blowing the module will get no power for diagnostics. The Legacy models have two ABS modules, one driver module which is located on the pump housing, and a main control module under the radio in the dash. From what I remember the manual said pin number 4 on connector P13? Is the power from fuse 18 for the control module. The "P" wire harness is for the Power windows, which means it is inside the car. The module should be visible under the ash tray area at the bottom of the center console/ dash. Link to comment Share on other sites More sharing options...

The one under the radio is mounted to the hump of the floor just forward of the transmission shifter and it's label is the SRS control box with yellow plugs to designate that.

You, like I was at first,......are looking at a 96-98 Legacy FSM The Imp it's seperate units. Download the service manual link that was poster in this thread earlier. That is for 95 imp.

Download the service manual link that was poster in this thread earlier. That is for 95 imp. I did that. but when i pulled the radio console and the center console out if the car to expose everything there, thats what is mounted to the car. and there's nothing mounted under the passenger seat.

But if you download pt.2 of that manual.......look in the diagnostic section, it's way down. This is the name of the PDF "MSA5TCD95I19351.pdf" about 3/4 of the way down in the diagnositic section. It clearly shows the ABS control module in the cabin...possibly under the passenger seat? Link to comment Share on other sites More sharing options...

There's only a heater duct under the passenger seat. I wonder on this '96 Impreza Outback if it happened to be during a change to a new configuration when it was manufactured?

whitetm Posted April 9, 2012 Author Share Posted April 9, 2012 You were right I ended up pulling out the passenger seat and pulling up the carpet and found it. Time to due a little processes of elimination to find out whats going on with it. Link to comment Share on other sites More sharing options...
whitetm Posted April 9, 2012 Author Share Posted April 9, 2012 Hey Gloyale, Well I plugged everything back in except the ABS control module and the fuse did NOT blow. I'm wondering if I should now disconnect each wheel sensor and plu the ABS control module back in and see if the fuse blows? If you have any suggestions to diagnose what could be bad, I would greatly appreciate it. I did talk to my nephew about the problems with the car and he told me ever sense the fuse link blew when the alternator went ballistic, thats when all the problems started. slowly but surely I've been correcting each of the problems and the only one left is the ABS situation.

naru Posted April 9, 2012 Share Posted April 9, 2012 (edited) ABS control module. Ohmmeter will likely show low resistance between the power input and ground Disconnecting each wheel sensor is a waste of time.
