My 2004 Honda Civic Coupe Manual Transmission has it's airbag light constantly on. Honda just did a recall on them for the Takata airbag issue about 3 months ago.
I learned how to get the error code from: http://forums.clubrsx.com/showthread.php?t=636707
And to me it looks like the error code is 2-3, but that doesn't exist in their form.
Here is the video of the error code: https://goo.gl/photos/SU2TdFcFbtFYNxzW6
Maybe someone can tell me if I read it incorrectly.
