Default 1989 Volvo 740 Turbo in "limp" mode?

Pretty sure my 740 Turbo is in limp mode. I think the SRS light on my dashboard, which correct me if I'm wrong, means there's something wrong with my airbags which may be keeping my car in limp mode? Anyone else having a similar problem? And if you did have a similar problem what did you do to fix it? Thanks, everyone for helping me with my previous post, I appreciate it.

afaik, SRS/airbags have *nothing* to do with LH2.2 EFI or the ignition system., there's simply no connection between the subsystems.

now, if your system voltage is too low, due to poor alternator, or bad grounds, or something, that could cause problems in both the SRS and the engine management.

I figured it may be that the airbag wouldn't engage which may of caused it to go into limp mode. But thanks for the advice.
