Reading SRS / Airbag codes '98 OBW- finding the connector!
Posted 31 May 2009 - 04:59 PM
I'm trying to sort out an airbag warning light on my wife's '98 OBW. I'm having trouble finding the diagnostic connector and none of the diagrams on line seem to match the pinout. (Wrong number of pins, wrong shape connector, etc.)
I've got an orange connector, a grey connector, a black connector and two green connectors all loose by the accellerator pedal. I know the green connectors (with a single wire going to each one) are not the airbag diagnostic wires.
I'd really appreciate any advice finding the connector and knowing which terminal to ground to read the codes.

Just did it a few weeks ago. Best 50 bucks I've spent in a long time.
CLock spring (or whatever Subaru calls it) was bad. On the way I realized the horn didn't blow and that it was probably the clock spring.
They found the ABS connectors (jambed BEHIND the fuse block and almost crushed), flashed the code. Grabbed a wireing harness section with a resistor and confirmed the clock spring.
I could have spent many days(partly because I'm not very good at electrical stuff) and don't have the necessary expertise or patience for any sophisticated electrical problem. SRS stuff is on a whole different level?
Replaced the clock spring on thursday and the light went off.

Once you get the airbag light flashing, the codes are 2-digit, with ''longs'' of 1.2 seconds indicating tens and ''shorts'' of 0.3 seconds indicating ones, with 0.3 second spacing. If there's more than one code, they'll flash in sequence, with a 1.2 second space between. As the EndWrench article states, the ''normal'' code is an on/off sequence of 0.6 seconds for each state. Be sure to note if the ''normal'' code is outputed following the trouble code(s), as that has meaning.
If you don't have the code list, post what you read and I can tell you what they refer to.

Added color of B82 connector

Just for kicks, I decided to examine the pass side airbag; got under the dash on the RH side and noticed two airbag related connectors. The connectors themselves were seated properly, but one of the wires had a mounting bracket on it which was loose, so the wire could flex. I repositioned the wire, cleared the codes and the SRS light is now operating normally. I'm sure the problem isn't solved - there must be a broken wire, a loose crimp connection or something. I'll monitor the situation and see if/when it acts up again and try to narrow it down.
