Electrical Gremlin....crash mode??

[4.6toddy]

Okay here's the symptoms
02 4.6IS

The X has been locked as normal. I unlock using either remote or key in door. When I start her up, the hazard lights come on, the dome light forward of sunroof (not the reading lights) come on, and all doors unlock.

There is no pattern that I can identify. Sometimes its cold out, sometimes warm. Sometimes it's been locked all night. Sometimes I've left it for 4 minutes. Key unlock or remote. Key lock or remote lock.

Sometimes it will go for a week without doing it. then it will do it two days in a row. sometimes it will go 30 key starts without a problem, then it will do it twice in 10 or 12 starts. Sooooooooo random.

Battery is new. Alternator is new. Belts are new. No codes show up on scan tool.


The only hint I have so far is that apparently when the X detects a collision (not sure how severe) it activates the hazard lights, puts the interior lights on and unlocks the doors automatically. Does anyone know anything about the crash mode? What would trigger it? What would cause it to think it's in that mode? a sensor? a module? a programmed code in the BCM?

Where the heck do I start?
