Need help with fault overload code1 by commodore

[James parry]

So I've been having some issues with my series 2 vy commodore Berlina other there week I started and drove my car got to my destination came back to the car 10mins later to it not wanting to start (well turns over then dies after firing ) After doing some research on this page I came to it being a few possible things dfi. Crank sensor. Keyhead I've replaced everything and it's still doing the same thing. The windows go down but the key doesn't lock or unlock the doors and the boot release in the glove box doesn't work the locksmith put his scan tool on the car and it said fault overload code 1 it's a long shot but would anyone know what code that is or anything I'm missing fuses are good fuel is good keys getting signal turns over fires then dies
