The supplemental restraint system could be diagnosed just like an ABS or Check engine light problem. I'd recommend you leave that up to an Acura dealer though.

The SRS has about 27 DTCs, more then half of them would require an SRS unit replacement as a corrective action. There's also a memory erase signal 2p connector.

If it occasionally comes on instead of staying on I would imagine that it's an intermittent failure that could possibly be erased.
