Any dash lights on? Do they all come on when you first turn on the key?
To check the systems you would need a good professional level scan tool or a shop with one. It would show you the various modules and you can test them. There is not a "crash module", there is an SRS module but it should not cause the other issues. It basically has impact sensors that trip and deploy the airbags.
In your case it seems like you have some bad wiring or damaged items.
Cigar lighter is fuse 12. And it also powers pin 16 on the data link connector. Check there for power. If it has power check the center pin of the lighter for battery power.
Do you have roof marker lights? Are they working? Radio works?
These share a ground with the cruise and 4X4 systems.
Beyond that a good visual inspection of the wiring and testing of the fuses might yield results. Use a test light with a good ground to test each fuse, I have had more than one that looked fine that was actually bad.
