greenieman7 Posted August 25, 2010 Share Posted August 25, 2010 Other than disconnecting the battery for x amount of minutes, is there a 'correct way' to reset airbag computer after repairs that the average idiot (such as myself) can accomplish without a full set of Subaru Official Tools?

mdjdc Posted August 25, 2010 Share Posted August 25, 2010 If the airbags went off you will have to replace the airbag control module. If you did not have the airbags go off, there is no reset for them. Just hook the battery back up and the system should be good to go. Link to comment Share on other sites More sharing options...
greenieman7 Posted August 25, 2010 Author Share Posted August 25, 2010 Expanding on my question, if any of you are very confident in your knowledge about airbag systems, I would like to run a diagnostics on mine. The connector (yellow) has 7 pins, 3 one row, 4 in the other. Looking at the connector (describing it from memory; I will recheck and correct if I have it wrong), pins facing me, 3 on top, 4 on the bottom, there is a dark green/white wire on top left, then light green/ red and dark green red to the right. Bottom row left, Yellow/red, white, blue, finally brown / red /black wire to the lower right. Reading other posts, its seems I want to jump the dark green white (upper left) to ground, then turn the key to on and look for codes. I would guess the br/rd/black wire is ground, although going directly to frame might be safer while staying well clear of the bag inflation path just in case. Anyway, am i close? If there is a link to a careful description of the process as well as a list of error codes, or if someone feels comfortable describing the process, I would be most grateful.

mdjdc Posted August 25, 2010 Share Posted August 25, 2010 You didn't mention if the system needed to be rebuilt due to having deployed. If the airbags were deployed you cando all the diagnostics in the world and you will STILL have to replace the main control unit. They are a one shot and throw it away unit. They do not have a reset. What type of repair work was done? Link to comment Share on other sites More sharing options...
greenieman7 Posted August 25, 2010 Author Share Posted August 25, 2010 To my knowledge it was not deployed; if it was deployed, it was deployed be fore I owned it Link to comment Share on other sites More sharing options...
greenieman7 Posted August 25, 2010 Author Share Posted August 25, 2010 Sorry; missed last question. Again, I don't know of any repair work. I am acting on the premise that a good starting point is running the diagnostics Link to comment Share on other sites More sharing options...
mdjdc Posted August 25, 2010 Share Posted August 25, 2010 I am assuming that your airbag light is on. If that is the case, then you definitely need to run diagnostics and get the coeds. Unfortunately, I do not know how to do that. I'm sure that there are folks on hee that know how to run the diagnostics though. Link to comment Share on other sites More sharing options...

OB99W Posted August 26, 2010 Share Posted August 26, 2010 It's much safer to use a diagnostic connector than one that's part of the SRS. See if you can find the one shown in http://www.ultimatesubaru.org/forum/showpost.php?p=668884 The connector and the "diagnosis terminals" ("ground probes") are usually under the dash to the right of the steering column, above the accelerator pedal. If they haven't been used previously, or were returned to the factory position, they may be taped to the harness, and appear to be a "lump" there. If you locate the connector (which should currrently have nothing plugged into it), let us know, and I or someone else can tell you how to use it to retrieve the SRS codes and/or clear the memory.

greenieman7 Posted August 26, 2010 Author Share Posted August 26, 2010 I found 1 single wire (black, possibly white flecks on it) such as in the diagram, not 2 and my yellow plug is a bit different as per above description, but could this be due to mine being a 1993, not a 1996? If this is correct, which wire do I connect it to? I would guess the brown/black/red one, but I would prefer to be certain with the key off, then turn the key to on to read codes, but I would prefer to be certain. Thank you Link to comment Share on other sites More sharing options...
greenieman7 Posted August 26, 2010 Author Share Posted August 26, 2010 I was able to find a single black wire (I believe with white flecks) taped up to the harness, but not 2. My plug is as described above; I am wondering if these differences are because I am working on a 1993 Legacy, not a 1996? Anyway, I I would guess that I plug this wire into one of the wires on the yellow connector, likely the brown/black/red one, then turn the ignition key on and read the codes, but I would like to be sure. Very sure! Thank you Link to comment Share on other sites More sharing options...
OB99W Posted August 26, 2010 Share Posted August 26, 2010 It seems like you didn't find the diagnosis connector -- it's not part of the SRS (Airbag) system, although it's wired to it. The 6-pin B82 connector is typically black in color. As I mentioned previously, you should find nothing connected to it (no mating connection). Look for a couple of loose green connectors (don't connect them) -- B82 should be nearby. Check near the bulkhead (firewall), it's possibly taped to the harness there. I also want to be very sure to give you accurate information. I believe that your "guess" about which wire to use is wrong. Could you verify the wire colors and locations (pin numbers) in the yellow connector? Please make sure to use lots of light, so that the colors are accurate. (It's easy to confuse yellow and white, for example, with insufficient light.) Link to comment Share on other sites More sharing options...
greenieman7 Posted August 26, 2010 Author Share Posted August 26, 2010 OK: I did not notice that the diagram in the link said black (otherwise I can not find where black was mentioned before), but anyway, thank you, yes the black plug is right there in front of my face :-) (I was myopically focused on yellow because of it being an airbag system). There appears however to be just one black single wire; the diagram shows 2. I have looked carefully. Unless it is tucked away in an entirely different harness. Is the correct procedure to connect the single wire into the the black wire in the plug, turn the key to on and read code? Thank you Link to comment Share on other sites More sharing options...

There appears however to be just one black single wire; the diagram shows 2. I have looked carefully. Unless it is tucked away in an entirely different harness. There should be two "ground probes", right next to each other, since both are used to clear the memory. (Diagnosis only requires one.) But just to be clear -- they're usually thinner gauge than others in the harness, and have a metal pin ("probe") on the free end. Is the correct procedure to connect the single wire into the the black wire in the plug, turn the key to on and read code? Thank you No, a black wire in B82 isn't for SRS diagnosis. And you're welcome. I want to make absolutely certain that you've found the correct connector. Please determine what color the wires going to pins #1 and #2 of B82 are (see the diagram for pin numbers), and get back to us. If they're correct, I'll post the procedure. Sorry if it seems that this is taking a long time to get to the point, but since you're rightly concerned about making an error, I certainly don't want to assume anything from about 3000 miles away (if "East Bay" is in CA). Some people have done damage to their cars by working with an incorrect connector and/or pin number -- let's not do that. Link to comment Share on other sites More sharing options...
greenieman7 Posted August 26, 2010 Author Share Posted August 26, 2010 OK: #1> blue, #2> white, #3 empty, #4>Red/Blue, #5> Black/white, #6> empty. I appreciate your approach. I dont want to blow my head off any more than you dont want to guide me into blowing my head off. Besides all other precautions, I will be well clear of the bag inflation zone at every step. ;-) I have looked again and again, pulled off all electrical tape in the area and still can only find 1 wire, a black wire with white (possibly silver) flecks that meets the description. There are other single wires, but they all have big plastic connectors on them. Link to comment Share on other sites More sharing options...
OB99W Posted August 27, 2010 Share Posted August 27, 2010 (edited) We're good -- let's start by getting the trouble code(s). Turn the ignition switch "ON" (engine not running). Plug a ground probe into B82 pin #1 (blue wire). The lamp should start flashing. The length and sequence of the flashing determines a code. Trouble codes will be in "longs" and "shorts", with the longs the first digit, and the shorts the second. Single digit codes have no longs. See my post #3 in http://www.ultimatesubaru.org/forum/showthread.php?t=114914 . Let the flashes cycle until they repeat, to make sure you get all possible codes. Once you retrieve the code(s), post what you get and we can tell you what they indicate. Edited August 27, 2010 by OB99W Fixed typo Link to comment Share on other sites More sharing options...
greenieman7 Posted August 27, 2010 Author Share Posted August 27, 2010 So, it is code 14. Link to comment Share on other sites More sharing options...
OB99W Posted August 27, 2010 Share Posted August 27, 2010 (edited) So, it is code 14. Code 14 indicates that at least one of the connectors to the airbags, front left and right sensors, or the control module are not properly connected. There are switches built into those connectors, and if they aren't properly latched the control module can sense it. Sometimes unlatching and reconnecting the connectors will resolve the problem. Before trying that, be sure to disconnect the battery, and wait for at least a minute so that the back-up capacitors can discharge. Make sure that the connectors are double-locked. Do you know where all the connectors are located? EDIT: The link below was unavailable for quite a while, but I just verified that it's back online. Download the PDF files (for '95, but should apply), and you'll have complete troubleshooting info for the SRS, including what the codes mean and how to check for the causes. http://hp.auto.ru/Subaru%20Legacy/1995/Service%20Manual/TROUBLESHOOTING%20SECTION/SUPPLEMENTAL%20RESTRAINT%20SYSTEM/ Edited August 27, 2010 by OB99W Added link to SRS diagnostics Link to comment Share on other sites More sharing options...

greenieman7 Posted August 27, 2010 Author Share Posted August 27, 2010 feeling stupid but cant find the airbag control module. the drawing makes it look like it is under dash on top of trans tunnel, but dont see it there, no big wire bundles lead there. is it under the shifter center console? Link to comment Share on other sites More sharing options...
mdjdc Posted August 27, 2010 Share Posted August 27, 2010 It is within the center console under the radio and ashtray. You need to take the console out and take out the radio and you will see it inside there. Look for the yellow wires. Link to comment Share on other sites More sharing options...
greenieman7 Posted August 27, 2010 Author Share Posted August 27, 2010 OK, thank you! Does anyone know how to clear codes with cars with only 1 single wire? I was able to read them with this wire, but as I understand it, there are usually 2 single wires. This car only has one; is there a different trick? Id like to clear and see if they come back. Disconnecting the batt does not do it. Thank you Link to comment Share on other sites More sharing options...
mdjdc Posted August 27, 2010 Share Posted August 27, 2010 You can only clear the code by fixing the problem that is coming up. Once the problem is fixed the airbag light will go out. This is not a system that stores codes. Link to comment Share on other sites More sharing options...
