Which PDF Manual ?

My Intro

My (jhs@) car (Subaru Legacy 1998) air bag warning light was iffy, then came on solid. Subaru Dealers had failed to fix several times { Retired first dealer seemed to improve it, but he wasn'' happy it would last, & he didn''t say how he''d fixed it (trade secret or more likely foreign language limitations) (I noted at 2019-10 that the cable reel (informally: Clock Spring) seal is broken). 2nd dealer had no time on 1 or 2 services, then mechanic admitted he did not like doing electrics}. ( Pages=4442_121M_liberty_1998_2003.pdf Page=3599 of calls this "Roll connector" )

My Battery

I (jhs@) disconnected battery, left it to stand, touched brake pedals in case any electrolytics anywhere in car might be storing charge.
Subaru dealers tell me Subarus do not have a supplementary 2nd battery, unlike some other manufacturers example BMW!-- Nigel warned me of BMW

My Static

My (jhs@) synthetic material shirts & non leather footwear can give static shocks Wonder if bags probably blow on real current to heat explosive, or can also blow just on voltage (like silicon chips) ? - so I (jhs@) grounded myself to wheel chassis before removing bag.

Name SRS & Takata

"SRS Airbag" just means "Supplementary Restraint System", ie they expect safety belt to have held your body back in a crash before the bag explodes in your face . SRS is not a trade name (as I had falsely assumed it was), so seeing "SRS" does not mean you don''t have a Takata air bag, Takata are bad news:

How To Videos

There are Lots of How To videos on YouTube.com, examples: Most for different newer models I (jhs@) do not have, with sundry different tips, inc. eg:

    Comments
    +Mart Brandjes: In North America OBD2 was standard in 1995 for Subarus.

    Bóbr Bobrowski 1 year ago
    in Europe some cars from 98 have OBD style socket with subaru protocol all after 00 have same thing and after 02 its full OBD support present

    Marc Instone 3 years ago
    Is pin 7 what they call the K-Line ?

    +Marc I believe that''s right. To be honest, I''m not really sure what it means, just haven''t researched it.

    BUSARU 1 year ago
    +Bóbr Bobrowski Sorry mate, I should have mentioned that in the video - 98 Legacy.

    jhs@:He lists where pin numbers on OBD socket go to, but Not to another older diagnostic socket on a Subaru, but to a Subaru ECM (ECU = Engine Control Unit) (for some VW project).

    OBD-II Conflict Of Pin-Out Numbering

    Subaru Pin numbering conflicts with industry standards, example all of The Subaru manuals I've looked at all have same pin-out numbering (all with pins 1-8 on narrow side, thus all wrong, as all inconsistent with wikipedia that has pins 1-8 on wide side of connector).
    (Maybe Subaru might have corrected manuals for newer models, I've not looked.)
    Subaru manuals:: It is important to realise how Subaru Pin numbering is screwed up, for when looking at Subaru circuit diagrams, & pin-outs of their other connectors, to figure how to connect wires from an industry standard OBD-II connector socket to a Subaru connector.

    How to read Pre-99 Subaru Engine Error Codes

    Join the 2 black plugs, turn on ignition (don''t start engine)
    "Check Engine" flashes (if a previous vendor has not crippled it).
    Count number of flashes
    If the CEL flashes regularly ie more than 6 long flashes, then there are no stored codes.
    Reset ECU by disconnecting battery overnight.
  • https://www.youtube.com/watch?v=DhDzA-6dFm4 Title: "How to check fault codes on Subaru Legacy forester, Impreza or outback WITHOUT scanner"

    Ignition off; Insert a wire in Pin 6; Ignition On; Starts & Ends with 11;
    [He had 2 fault codes to clear.] To Clear: Leave Ignition on; Remove pin 6, ; 3 times within 12 secs, hold in for at least .2 of a second; Pin 6 Back in & leave. Ignition off & on; Should now just show 11; Remove pin & insulate.
    I tried this 2024-04-05 it didnt work, I still have same My trouble codes: when I earth pin 1,

    This DIY video applies to all 1993-2001 Subaru Impreza models, however, Subaru used this diagnostic approach for many other models over the years, so this video actually has a much broader application across the entire platform. www.SubaruONLY.com

    youtube . com / watch ? v=3y55wdRsa3Q By Justin in Seattle on a 1992 Subaru Legacy
    Light brown (became yellow by my later car) plug:
    is oldest Subaru plug for diagnostic scanner.
    Called: Select Monitor One.
    Looks like 4 slots in a row, + 1 small hole in middle . But I think its actually 9 pins. Was normal up to 1995, still present in some models after

    Called D (Dealer) Check Connector.
    2 contacts at right angles
    turns all solenoids on. (I (jhs@) tried it, on & off maybe each second)
    Listen for solenoid clicks & fans whirring.
    2 black Connectors
    2 Connectors (I (jhs@) think
    for error codes "U Check")
    Singular black connector:
    7 pin, used with ground wires, to set a condition to get more error codes

    top left of U is pin 1, top right is 2,

    there are 2 loose pins for shorting
    depending on model both black, or black & white.
    • pin 1 if earthed (with ignition on): initiates error display
    • pin 2 if earthed as well as 1 (with ignition on): clears error memory.
    • long blink indicates decades of error codes 10, 20 etc,

I (jhs@) needed to mentally rotate connector, as it''s an oblong stretched U format (not a square or round pin connector). & mine (jhs@) appeared with pins 1 & 2 apparently down, not up :
      • Blink on for 1.2 secs is decades, eg: 10, 20, 30
      • Blink on for 0.3 secs is units, eg: 1, 2, 3
      • Steady on & off with each 0.6 secs = all OK, no error.
    • Note the error (or all errors, may be more than one). To clear the error log: Put 2nd wire in pin 2 while blinking for minimum 3 secs.

Video Title: "Subaru OBD1 Scanner - The B10 scan tool"
- The B10 scan tool Selector Monitor Connector is a mid brown (the software on screen says "Yellow 9-pin Subaru Select Monitor port", my screen shows dark yellow), one can make a cable with a subaru stereo plug to parallel port of a PC. Software running shows on his screen as:

The video has a picture of a translucent nylon plug (ie male pins) that would fit the yellow socket in my car.
He says same sort as used on Subaru stereo.

Diagnosis Connector: Yellow 9 Pin - Same as above I think

Looks like may be same plug as would fit socket pictured on front page of adapter cable on "Select Monitor - Instruction Manual - Technical Trainiing" SSM Intro Booklet0001.PDF ssm_intro_booklet0001.pdf from http://www.subaru-svx.net/forum/showthread.php?t=45762
9 pin connector, yellow
Picture of a yellow 9 pin "diagnosis connector" from surrealmirage . com / vrg3 / b10scan/ Titled "B10 Scan Tool", Where they call it a diagnosis connector,
But my (jhs@) manual calls a different plug a Diagnostic Connector (6 Pin Black B82)
(but I (jhs@) have pictures of that yellow plug in my (jhs@) car, (a green plug seems adjacent in photo, though depth of perspective unknown) though my (jhs@) car is a next generation Legacy 2)
"B10 Scan Tool
This is a very simple scan tool to read some parameters in real-time from the ECU on 1990-1994 North American Subaru Legacy models using x86-based computers.

Select Monitor connector Under the driver side dash there is a yellow 9-pin diagnosis connector intended to interface with the Subaru Select Monitor."

Notes from https://www.youtube.com/watch?v=3y55wdRsa3Q by (Justin at all wheel drive auto)
  • My 1998 Yellow are shown as his 1992 Legacy pale brown/ tan. He calls it "subaru select monitor one", for up to 1995, still on a few models after
  • The 2 green single spade are "Dealer Check" only connected to cycle all solenoids on & off so technician can easily listen to stuff
  • 2 Black single spade are called "U Check connectors": Connect first then turn engine on.

  My (jhs@) Log & next moves

  • Done

    • My (jhs@) Case:
      • My (jhs@) car is older than cars in most videos, it does not have an OBD-II connector socket
      • I''ve taken off: air bag, steering wheel, & flexible flat ribbon cable reel (the circular disc containing thin flexible ribbon cable that American youtube videos call a "Clock Spring").
      • My (jhs@) car has just 2 (yellow) wires on the back of the air bag (though I (jhs@) have a horn too).
      • 3 other wires out of the cable reel all go to a 2nd white nylon plug with just 1 pin : which connects to steering wheel chassis, (bottom most nearest edge of wheel)
      • The assembly of the air bag is on 4 nylon posts/ locaters, presumably insulated from chassis of stearing wheel except when the horn = airbag assembly is pushed, when presumably it touches wheel chassis.
      • When the system is powered up with a dummy resistor instead of an air bag, the air bag is still on (not suprising it probably would remai so unless cleared which I dont have a note that I tried, so probably I did not try to clear).
      • There is about 9V between both terminals of the dummy resistor & stearing wheel chassis.
      • I can''t see one of the resistor terminals being more positive than the other.
      • I took lots of photos, some could go online later.
      • My (jhs@) car has no standard shape OBD Connector, though there is one (maybe 6 pin) plug hangs loose near steering.
    • I tried the 6pin b82 with pin 1 & 2 method - 5-5_[T4A1] = Page=2150 of Pages=2436_86M_1998.pdf) Didnt work.
    • I tried the 6pin b82 with pin 6 in & out method: Didnt work
    • The pin 1 does show error codes, so that proves at least 1 of the 2 test wire works.
    • Remove lower facsia to get access to connectors
    • Checked both Diagnosis Terminal are less than half ohm to earth. (Manual show them as earthed at Page=2001 of Pages=2436_86M_1998.pdf)
      This was checked when green led in middle of a cig. socket plug was glowing, (Unfortunate that it was glowing, cos I''d wanted to test when no power to cig socket, to see if that intermittent fault was assoiated with a common ground fault or just an intermittent +12V fault.)
    • Found location of ECM (Engine Control ) : Passenger side ! Section=2-7_[T2A1] Page=1291 of Pages=2436_86M_1998.pdf
    • Now cigarette socket & air select light happen to work, (perhaps indicating some intermittent earth is currently working), Tried clearing errors usin the pin 1 & 2 method. Failed again.

  • To Do Next

    • Wiggle just all yellow cables. (yellow is an industry standard, regardless of manufacturer)?
    • Confirm theres nothing but heating cable in seats ?
    • Maybe try & set the connectors before turning on ignition ? as shown in https://www.youtube.com/watch?v=g1K7PqhmDW8 - Up to now I''ve turned on ignition then set the pins
    • Disconnect cables from battery & short out the cables to reset any ECM computers, or leave to run flat (how long ?!)
    • check fuse no 8. = middle row left
    • To access ECM: Remove glove compartment probably near (Page=1226 of Pages=2436_86M_1998.pdf)<<!--}-->
    • Locate ECM Connector B84 Pin 93 Colour=OrW (From Section=6-3_[D1A0] (Pages=2436_86M_1998.pdf) is Orange base White strip ), Doesnt seem to be connected to anything else - is there even a cable resident or is it an unused connector ?
      Add Cable to my OBD-II Wiki Pin 7 (K-Line).
    • cd ~/public_html/txt/airbag; vi manual/tree/subarulegacy_1998/1998/service_manual/diagnostics_section/supplemental_restraint_system/all.txt
      Check connector (AB6) connected to airbag con-
      Also check connectors, terminals, wiring harness
    • Wobble all connectors on yellow circuits
    • cd ~/public_html/txt/airbag; vi manual/tree/subarulegacy_1998/1998/service_manual/diagnostics_section/supplemental_restraint_system/all.txt
