This is not a TSB (no TSB issued for this problem that I can find), but rather an article that appeared in the July, 2005 edition of Honda Service News. Text below (sorry but they never cut and paste properly):
Power Doors Lock By
Themselves or Cycle Twice
NOTE: This article applies to ’03–05 Accords,
’05 Odysseys, and ’06 Ridgelines.
An open (ungrounded) driver’s door lock knob
unlock switch can cause the multiplex-controlled
power door locks to lock by themselves or to
cycle twice to unlock and then lock.
What’s going on is the multiplex control unit
"thinks" the driver’s door is locked. To try and
restore the unlock signal, the system unlocks the
door twice. The system then goes back to its
default position by locking the doors.
To fix this problem, here’s what you need to do:
1. Connect the HDS to the 16P data link
connector (DLC). Turn the ignition switch to
ON (II). Turn on the HDS.
2. At the screen prompts, enter the VIN and the
odometer reading.
3. From the
Select Mode screen, select Honda Systems.
From the
System Selection Menu, select Body Electrical.
4. Select Door Locks, and then select Data List.
5. Scroll down to the driver’s door lock (unlock)
data, and read the screen. The list says
ON when the door lock knob is unlocked;
OFF when it’s locked. If the driver’s door lock inputis incorrect, go to step 6.
6. Check for an open circuit in the WHT/BLK
wire between the door multiplex control unit
and the driver’s power door lock switch. If the
wires and connections are OK, go to step 7.
7. Check the lock knob switch ground. If it’s OK,
then replace the driver’s door lock actuator.
