Ok, let's think about what "wakes up" those indicators. I know that turning the key on does, and turning ANY exterior lights on will as well. Opening the driver's door will.

Do you have the lights off? (**** points up.) Do all lights time out and go off?
If yes to both...

Does opening the driver's door turn the dome light on? If the key is in the ignition and you open driver's door, does the buzzer start up to tell you so?
Does the "key in" buzzer activate when it shouldnt? (That is, if the key is out and you open the door, if the "key in chime" sounds, then the key in sensor on the ignition switch is lying about there being a key in the ignition.)

If not the door ajar switch (there are two on the driver's door, one turns dome light on, one tells the system the door is open) may be indicating a constantly open driver's door.

I suppose a stuck traction control relay or engine control relay on the RCM could cause this, tho that is really unlikely and either would drain the battery in a matter of three to six hours.
