1993 Legacy Airbag Reset

[OB99W]

Yes, fixing the problem that's causing the warning light to come on will allow the light to go out. That's a good way to tell that the problem has been repaired.

 

However, most of the codes are stored in memory. One reason is that a problem may be intermittent. The memory ensures that even if the light is out (because the problem isn't occurring currently), a code history can be retrieved so that you can diagnose the intermittent problem.

 

Any codes can be cleared using the correct procedure, but only if the problem isn't happening at the time. Currently ocurring SRS codes can't be cleared to "see if they come back".

 

Pin #2 (white wire) of the B82 diagnosis connector is used for clearing memory. It needs to be grounded, as per the manual pages that I previously gave a link to. But first the problem should be repaired so that the warning light goes out.

Thank You. Ididn't know that. I had never seen a reference to clearing the codes, just fixing them. I guess I learned something new. I love this board for that reason.

Something I found out this weekend. My friend had a 95 legacy withthe aribag light on and we could pull no codes from the control unit. After much searching we found that the green safety latches on oa few of the airbag connectors were not locked. It seems that these connector locks finalize the connection and if they aren't locked the airbag light will stay on. We found the ones that were unlocked and locked them. Immediately, the airbag light went out.

 

I don't kinw if this will help you out, but I just wanted to put it out there.

Yes, and code 14 which the OP reported is specific to improperly locked connectors. See my post #19 in this thread.

I understand the 14 code, but all we got was a constant airbag light and the book had an entire laundry list of things to look at. WE aere going to take the dash out to inspect for other problems when i decided to look at each of the connectors. Maybe because it was three connectors the module couldn't read out a code. Not sure, but glad that it is now fixed. I really didn't like my friend driving around with inoperable airbags.

 

Thanks for your help too.
