After i reset my ECU to get rid of a CEL, my doors infrequently all lock (except the drivers door) when I close the drivers door. Not everytime though, I haven't quite figured out the exact conditions that make it occur, but it does happen quite often.

When all the doors are unlocked, and I get in OR out of my car, and close my drivers door, every door except the drivers door locks. Never happened once before resetting my little ECU (if that's what you want to call that box.)

Is this a setting you can setup?

The ECU has nothing to do with your door locks.
The module that controls them is a totally different unit.

 

That's what I would assume, but I'm not just imagining this. I remember the first time my doors started automatically locking was shortly after resetting the ECU (first time it was ever done, had to cut out the plastic protector for the screw.)

Not just making it up.

Do anyone elses doors auto-lock?
