Vectra B 150 error codes

Dazerc

my friends vec B 2.2 150 had the ecu light on. i plugged my laptop in to see the error codes and it had C3f03, C3801 and P3000

I then reset the codes the light went out but some other codes came up C3F03, C387F and P0312 saying cylinder 1 2 misfire detected.

The central locking doesn't work even with the key in the door.
The car runs fine with no misfires and isn't down on power.
anyone know what the codes are?
Thanks

I am sure someone will help out with your question soon. One fault on a car can make others play up til the one fault is fixed. It happened on my 2.2 Astra Sri, I had one fault making 2 others play up even though they were ok.
