the dome light won't turn off during normal circumstances when the selector is in the "door" position.

situation:
1.) the door-ajar indicator in the instrument cluster is off when all doors are closed- as usual. the dome light would still be on as well as the keyhole-illumination-ring; those remain on after all doors are closed and after those ~30 seconds that they're supposed to turn off.
2.) the dome light and illumination ring remain on after doors are closed, car is started.
3.) the dome light can be switched off in all above circumstances manually by selecting "off".
4.) illumination ring is on as we speak (i'm not concerned with the draw from that puny led).

so naturally, i turned to these:

^general gen5 info.

http://www.camrymanuals.com/manuals/02/Power_Source_Current_Flow_Chart.pdf
^basic power flow chart

http://www.camrymanuals.com/manuals/02/Interior_Light.pdf
^related wiring diagram from fuses-to-grounds.

i studied the wiring diagram. i've electronically checked the fuses: "DOME" (7.5A), "ECU-B" (10A), and "ECU-IG" (10A). none of them were busted. i've tried to remedy the situation by replacing those fuses anyways and checking the other fuses that might cause the situation (i would skip the power-seat fuse for example), but the situation stayed the same.


so what's up with that? did i miss a fuse, fry that "body ecu", or managed to get a harness disconnected?

that's just the obvious one...just unscrew the kick panel and pull it out and you'll see all the wonderful cables :D

but i'm not sure whether the US version have different plugs.. but the one i have is a white plug with two wires attached to it.

^dome light trigger? i'll check up on that tomorrow- as well as possible harnesses/plugs.

1:30 a.m. over here. i can't sleep on this so easily =(

thanks. hopefully it's a plug/harness. i really hope it's not a fried ecu.

it's been a while, but...

^i'll check on that. i'm having doubt that it's a faulty switch, cuz the door-ajar warning goes off when i close the door, unless that has nothing to do with it...
Does the remote key fob work to lock it?
yeah. if the fuse for that (which happens to be one of the fuses for the dome light as well) is also fine.

Find a similar camry in a salvage yard, With identical options as yours, ask them if you can swap BCM's with yours and see if that fixes, if so give them money for the module. Thats about all i can say to do from here.

holy crap... that whole thing i was staring at for the past couple months was the body ECU?!?!? :lol: for the whole time, i thought it was behind that thing or somewhere in the passenger side... LMAO

thanks a lot jsm and pooh. you guys have been great help. looks like i'll be going to a junkyard later if i'm unsuccessful with all the suggestions..
