SRS Warning Light

For the first time, I was driving my 1993 NSX and the red SRS warning light remained on for about 15 minutes and then went out. I checked the service manual and it said if the light remains on or flashes, to take it to Acura for service. Has anyone else experienced this or heard of it happening? The manual only indicated a ten year maintenance check for it.
 
Did the "check engine light" also activate at the same time? I had a problem a while back where the check engine and SRS light activated and remained on until the module was replaced. Do a search for "check engine light" and you wil find what I determined to be the problem.
 
I had a similar problem with my 95. The SRS light would only come on under high performance conditions that I could repeat consistently. Basically the problem occured when the car was warm and pushing it into a tight right turn at just to point of starting to drift.

I tried to figure it out myself but finally took it to the local NSX tech. We went on a spirited test drive where I was able to make the system fail several times. After he blew chunks (just kidding) he spent about 3 hours trying to locate the problem with the help of Acura support. BTW he had one of the biggest smiles on his face because he said he's never been on a drive like I gave him.

Ultimately the problem was a connector under the center console that was being strained from my driving. The tech figured it occured from a combination of road vibration and hard braking followed by quick snap turns. The weight of the wiring harness in this area under the conditions was twisting the connector they figured. He re-inserted the connector and put some supporting ties on it so that it wouldn't happen again.

Can you repeat the condition? I'd try to identify the speed, g-force, turning direction, braking, vibration, etc. My tech told me the test drive with understanding these factors help him and Acura support narrow it down to either the SRS light, SRS light connector in the display console or the main connector behind the center console.
 
Thanks for the tips NSX4U2. The engine light did not come on but I will trouble shoot the check engine light.

hejo It is not like I don't push this sweetheart (I did have a Ninja ZX-12R a 200 MPH sportbike until I totalled it in May); I have found the rev limiter more often than naught...however, I think I would enjoy one of your spirited test drives if I am ever in Oregon! There is something about your wallet being 6 inches off the ground going over 150 MPH that I still haven't gotten use to yet! I was unfortunately going 55 MPH and will try to replicate. Thanks for your tips and sharing your spirited test drive story.

Well I feel a little stupid. I replicated the warning light anomaly. I drove in to work with no problems. I start the car to return home at the end of the day, and the warning light is on. The sun was baking the cabin and dash to "who knows what temperature"; when the cabin cooled down from the air conditioning (approx 15 minutes) the light went out

Sounds like a connection problem, either a connector is lose or you may have a cold solder joint. Remember my problem only occured once the car had been run hard and was up in temp. The radiator hoses run down the center and heat the center console some. That's where the main connector is and was the one that was lose on my car. Check it out.
