So today I get into my car (97 sohc) and the SRS light is on, so can I figure out whats wrong by pulling the codes with a normal OBD2 scanner, or will that not work? If not how do I find out whats throwing the code.

Some scanners don't support SRS/Airbag but worth a try. I'm assuming you only have the driver's airbag as it's a SOHC or do you have passenger airbag as well? Usually it's just the airbag but sometines the seatbelts can set it off and the sensors in the front bar. Can't remember what these things have LOL. Have you recently unplugged anything?
It has both airbags, and I haven't messed with anything recently so I am thinking it is the seat belt. It doesn't like to go back into place, you have to feed it in. I have only heard of this problem a couple of times which is why I am suspicious that it is one of the airbags.:(
Try disconnecting the battery for a minute or so as it will clear any codes and see if it comes back. If you do change the seatbelt do it while the battery is disconnected as it will throw the code again as soon as you unplug the seatbelt sensor.
^ what he said. My SRS light came on when my battery died and I couldn't figure out how to turn it off. There weren't any problems and I couldn't use a logger to figure out the problem. Fortunately, the light went away after a few days of normal driving. Disconnecting the battery for a few minutes and then hooking it back up ought to clear any memory that your srs computer has of a fault and it will not return unless there is a recurring problem.
Thanks guys, if the light comes back on I will try to use a logger to figure out what the problem is.
P.S. Joe, your gto is epic.
Thanks mate. Pic in sig is pretty crappy cus it was taken on my phone. But I love it. My missus can't understand it LOL. Mind you she likes dumb stuff like shoes hahahahahahaQuote:

SRS light is not affected by seatbelts. SRS is for the supplemental restraint, aka the airbags, and the airbags alone. The seatbelts are in no way connected to the SRS computer or ECU.
Wasn't sure about that one. I have had experience with other cars where this has happened. If the sensor in the seatbelt fails or is unplugged the airbag light comes on and must be cleared. Same with the sensors on the front bar if unplugged or faulty. So I guess the 3000GT/Stealth doesn't have these sensors?
Nope. It wouldn't make any sense to me that any car would honestly. If there is a seatbelt error the airbag is a back up. If a seat belt error causes an airbag error, then doesn't that defeat the purpose?
Nope.Quote:

Also, disconnecting the battery only seems to work if the light was triggered by a low battery condition.
All other errors are stored, and maintained by the SRS unit's internal battery.
They can be cleared by the $ealer..
FWIW the low battery condition can also be cleared by turning the key off and on (don't start the car, just turn it until the dash lights up) 30 times. (I guess that's supposed to be ~ two weeks of driving assuming two trips a day?)
BTW - I agree with Stealthee, tying the seatbelts into the SRS doesn't make any sense..
You might be thinking of the Butt sensor that some systems use to enable the passenger side air bag?
It's part of the safety restraint system and will give a warning to say it's not working. I have seen this on Volvos, Fords and GM. However our cars must not use it.
[QUOTE=Steve '92ES;22618]Nope.

I think I will give that a try just for the hell of it.
I won't touch the making sense part... That's the engineer's department. I just fix them and don't try to make sense of it all. But in comparison, our restraint system is pretty old school. Most modern systems have seat belt pretensioners that blow the seatbelt buckles back in a crash, as well as body weight sensors in the seats. I fix seatbelt related SRS codes all the time...Quote:

I have had this light on for about a year now but never cared since I heard a lot of people get this random light for weird reasons. My seatbelt doesn't feed itself back in but I dont know if that is the reason or not.
As has been stated, a 3S SRS system does not monitor or know anything about the status of the seat belts... The consequences of the light being on vary depending on the code. The system could be fully operational with a code in memory, partially handicapped, or fully shut down... I've never really checked into the failure management strategy on these particular systems, so I don't really know the specifics of how they handle each different code.Quote:

Any shop with a Snap-On scan tool and the Asian software can hook up to the SRS. That's all I use...Quote:

I've mentioned this at the old site before, but the back up fuse is tied into the SRS system for god knows whatever reason. When i bought my 96TT years ago, the SRS lamp was on. I drove to the old Mitsu dealership that i used to work at and plugged in the MUTII and pulled the code "## Low IG voltage". As i attempted to clear it, it would not clear. Checking the wiring diagram, noticed the SRS was tied into the "reverse lamp" circuit. Wouldn't you know it, but my reverse lamps weren't working also. I traced my reverse lamp failure to the backup fuse under the dash. Once i replaced the fuse, the SRS code was able to clear with the scan tool. Of course, the light came back on again the very second i dropped my transmission into reverse (i ended up having a failed reverse switch at the transmission that would blow the fuse in reverse). I ended up replacing the switch, installing a new fuse, reclearing the code- and all has been well since.
This "Low IG voltage" code can also appear when disconnecting your battery with the ignition switch in the ON position. So when doing any service work that requires a battery disconnect, be SURE the key is off before disconnecting the negative cable end.

From what i remember back in my days with Mitsu- if the SRS light is off, the system is defeated (off). If there are stored codes, but the light is off, the system is operational.Quote:

This is good, seeing as the closest mitsu dealer is 2 hours away.Quote:
