Need canbus ID for controlling dome and footwell lights

[stephtech]

I got a black interior and the 4 reading lamps are just not bright enough at night. I am adding a led dome light in the middle of the headiner (no pano roof) and want to control/ connect it with the driver reading lamp. I am ok for the electrical connection portion.

My goal is to install a physical button attached micro controller that would send CANBUS messages to turn on all reading lamps AND the footwell lamps at the same time as there doesn't seem to have a manual way to turn those on other than opening a door or parking the car.

So I am looking for canbus messages to control the interior lights. If haven't found them in the lists floating around.

thanks

I would attach an analyser to the body canbus and turn them on/off a few times recording the time you did it, then sift through the logs. Take a bit of time but shouldn't be too hard.
I've done this with BMS commands and found them without much trouble.

yeah, I can do that but the one that would be harder is for the footwell as there is no control for it, maybe opening closing the doors might do the trick.

If nobody has the info, I might have to do that.

Please let me know if you find the messages for the footwell lights.
