    Hi, i have two fault codes stored in the conv ECU,

    01811 voltage for door controller driver side (j386) faulty
    01812 voltage for door controller pass side faulty

    central locking, electric mirrors and the iluminations for both the front doors don't work.
    Fuses are all O.K.

    Has anyone had an issue like this?

    I know its both doors, but check the door hinge rubbers, wires break in there.

    The fact both are down, does make you think its elsewhere, but whats 5 minutes going to hurt you checking.

    Check fuses.

    Thanks for the replies guys.. checked the driver door harness and found that i had a live missing. Re checked the fuse that fed this wire and found a break in the spade of the fuse and not the fuse wire. so when i looked at the fuse in the first place it looked ok.
    So replaced fuse and everything is ok :)
