Well, my '93 Seville really really REALLY wants me to have that airbag system serviced.
So much so, in fact, that it's locked me out of reading any engine data 10 seconds
after I turn the ignition on. I can quickly scroll through the coolant temp, volts, oil life,
and fuel used, etc. but the "Service S.I.R." message comes back and stays there
until I shut it off again.

I've determined that the root cause of this is a bad ground somewhere, but I
haven't had the time or the patience to trace it down. Mechanic said not to be too
worried about the airbags not working should (god forbid) I need them, but cautioned
me about pulling fuses, controllers, wires, and whatnot. I'd rather not if I can avoid it...

Is there any way to bypass this (and other stuff) through the diagnostics mode? I've
played around it a little bit and know you can change settings and values and whatnot,
but I have no idea what I'm doing. I just changed the oil, and would like to reset the
oil life thing, but it won't even let me do that.

Thoughts? Ideas?

===============================
I suggest getting the FSM - Factory Service Manual -
I found the 2-volume set for $30 - with free shipping -

through the diagnostics mode?

I doubt there is a way to bypass the SIR system -

as for "other stuff" - the best answer would be "maybe" -
but usually any changes made through "diagnostics mode"
would be temporary - and limited to one ignition cycle -

I've played around it a little bit
and know you can change settings and values and whatnot,
but I have no idea what I'm doing.

the FSM lists ALL the parameters - and ALL the values -

I've determined that the root cause of this is a bad ground somewhere,
the FSM will help you trace electrical circuits -
and ground locations -
