    1998 deville "theft system"

    Every time I start my deville it says "theft system problem car may not restart" but it always starts. Sometimes it will say "starting disabled wait three minutes" then it will start. Is it something to worry about? And what causes this problem? Thanks for any help.

    Pull codes, bet you have a VATS issue and do you have stock HU in the car?

    They'll be "B" codes.

    Do you not have an option to pull ALL codes? By module only?

    PZM I believe... possibly IPC. They will be B codes...
    Do what I do...video them all on phone and look at in the house while you figure it out.
