If you go to a local autozone they will scan it and tell you the code/meaning. That would be your best place to start.

You can clear code by turning key on and depressing accelerator 5x's. the down side is you remove it and won't be able to see what the issue was

Does anyone else know if the NSBU is known to go out on this year? I know on a LB7 this would sound like a bad NSBU.
