Looks like the problem is some sort of failure in the little box under the
drivers seat that controls the passive seatbelt system. This little box has
all the relays and logic in it to control the movement of the belts using
the door switches, and little switches on the belt tracks to tell the box
when to move the belts, and in which position the belt is in, and whether or
not the belt is locked in place. This box has one wire that runs from it to
the instrument cluster to turn the little seatbelt light on and off. It
also has 2 wires that run to the cars ECU that control that little beeper
that comes on if you leave your lights on, or when the belts have not
reached their fully locked position after you get in the car and close the
door.
Solution: If you are somewhere in the states I would take the car to the
dealer and tell them you are having problems with the passive restraint
system, and that there is a recall to have this system including I would
assume the little control box checked out completely. If the seatbelt
system is under warranty for life like I have read on this egroup then they
should honor this request free of charge.
If you can not get to a dealer from the states, like me and other
non-stateside MX3ers, then I have come up with a way to disable the light
and the beeper. It involves taking the 4 bolts that hold the drivers side
seat out, removing the seat, taking the connector off of the seatbelt
control box, and using a small flat tip screwdriver to extract 3 pins, the
above 3 pins that I mentioned above that control the light and beeper. Here
is a link to a picture of the connector showing the 3 pins(highlighted in
little grey boxes) that must be removed:

Of course there is also the option of buying a replacement control box if
the dealer blows you off, and you don't feel comfortable disabling the
little warning light and beeper. I understand the fear that without the
warning light and beeper we will not know if the seatbelt control box is
working correctly, and since our shoulder belt working correctly, and
"safely" is in the frey on this problem. I personally don't mind the risk
because I can hear my seatbelts lock when they come all the way back in the
tracks, and I pull on them and they don't move a inch.
