I'm sorry guys, I know I'm probably getting a little annoying here but I've been reading some of these threads and I'm getting a little worried about a few things.

When I crank my accord, the D4 comes on momentarily on the dash display, is this or could this be a problem later on?

When I open the driver's side door the dash display shows that all doors are open on the little accord silhouette, this car has an alarm system which I have disabled, is this something that happens normally or do you think that it's associated with that POS annoying alarm system?

My ABS light comes on sporadically, I checked the reservoir and it's full, how would I go about servicing this? Do I need to just bleed the brakes or is it a more intensive procedure?

On a completely off-topic note, just for my own knowledge here. Is the front differential open, or limited slip?
