I heard a lot about the BCM (body control module). As far as I know it controls almost the whole electric (power windows, power locks, keyless entry, alarmsystem, ...)an all 4th gen. Maximas have it.

My question is, can it be programmed (by my dealer) ? Because in my car the turnlights won`t flash when locking/unlocking the doors by remote. All other Maximas I know do that. I also can`t make my windows go down when I hold the unlock key down - other Maximas do. Or is is possible to programm it, so the the power for the power-windows stay on about 30 sec, after removing the key or so.

Thank you for your help !

Sorry for my bad English.

 

I believe that the Max's that came with a factory alarm and other remote features are controlled by a seperate control module. It's actually smaller than the BCM. With this little box/module, programming can be done. I would have to see one to know exactly how it's installed in the car, though. I had seen one on Ebay a couple of weeks ago if your trying to purchase one.
