power locks not working

I have a 2003 accord ex-l sedan V6 AT with power door locks and keyless entry. The issue I am having is that the doors will lock via the switch or keyless remote. Unlocking works both via switch and keyless. I can lock them manually by pushing the knob down on each door(1 by 1). if I put the key in the drivers door and lock it, only the drivers door will lock.



Looked online and in the FSM, all pointed to actuator. I changed drivers door actuator, no dice. After I replaced the actuator, it seems like all doors unlock when I unlock the drivers door with the key. Sometimes when I shut the drivers door (without locking) the alarm will activate and go off when I open the door again.



The door switches seem to work, when doors are opened the dome light comes on as it should and goes off when doors are shut.



Anyone else have this problem? Could it be the MICU?

With the MICU you would never know unless you took it to the dealer. They would be able to control the functions of the car using an HDS unit (Laptop and a MVCI hand held).

MICU is a pretty expensive part to replace. So your best bet is to hit up the local Honda dealer and have them diag it for you.
