No, that doesn't apply to your truck. The AAM was redesigned in 2002, and actually I think this was all fixed by 2000 in production vehicles. The DTB you linked to relates to the 98s and 99s. There is a wiring change that would allow the seats to legally operate with the key off.
I had time later in the day to reacquaint myself with what I was trying to remember from past experience with the 2002 and newer trucks.
What the 2002 intro book states is this:
Convenience control
-If the ignition/start switch is moved from the On to the Off position and the front doors remain closed, the convenience control (power windows, sliding/lamella roof, seat adjustment, exterior mirror adjustment, interior lights) is active for 30 minutes. If one of the front doors is opened, the duration of the convenience control of 30 minutes is restarted. On US models, only the seat adjustment is still active after one of the two front doors is closed.
What I discovered today (or rediscovered I guess), is that if you leave the door OPEN for a half hour, the interior lights will shut off and the seats no longer work. I then closed the door, and the interior lights came on. I should have checked at that point if the seats would work, but I didn't. I am almost 100% sure that if the lights were "on" that the seats would have operated. I reopened the door right away instead, and the seats did operate.
If you are sure that the seats are inop immediately after shutting off the engine, I would say there is a problem with the programming in this truck. Maybe you can go to the dealer and ask them to look at it. Show the what it's doing wrong, and also possibly you can ask them to compare it with a different 2003, like on the showroom, and they can figure it out. Hopefully it's just the version coding in the AAM. Are the dome lamps working normally?
