Disconnect the battery and fully charge it. The number of flashes does
reveal a coded fault message but it usually stems from low battery rather
than actually faulty airbag.
had the air bag light come on multiple times on the way home tonight.
on off on off. also the wipers were acting sort of flaky at the same
time. any ideas?? 1990 Miata.
Battery is only a year old. another thing that happened, would not
turn over tonight and appears to be the igition switch. figure maybe
it was not making contact and the air bag ckt was reseting.
from reading many posting at miata.net, my understanding is that a
blinking air bag light can be due to a faulty ignition switch. the
solution suggested over there is to exercise the ignition switch with
the key by moving it back and forth several times. that might be all it
needs to clean out some dirt clogging a contact. but a bad ignition
switch is also a pretty common issue for those that used heavy key
chains in the miata. there are also issues with the capacitors in the
air bag control module that means replacing the module (unless you have
some well honed soldering skills and want to get inside the module
itself), and there is some talk about failed fuses inside of the air bag
module itself that is not user replaceable.
but enough hearsay... this is what rod's manual says:
"Turn the ignition swith to ON and observe the airbag warning light in
the instrument panel.
