You did not remove the seat did you at any time? I have a 2003 Civic
that had an XM satellite radio installed where they mounted the power
converter under the seat.The SRS light came on due to the disconnection
and would not go out.There are some kind of seat connections that tie
into the airbag system.
The radio installer did not have the "code" to cancel the warning
light.So,I had to take it to the dealer to have it reset.I am not saying
this is your problem;just a thought.
