The body control module (BCM) control base on inputs from door jamb switch, dome lamp switch or door handle switch. The BCM will supply a ground to the courtesy lamp relay when closing any one of the above switches to ground. the only way to find out is with a voltmeter and wires diagram checking all the input wires from the switches above, if you find a ground in one of this input that's the culprit,, other way you can unplug all the switches but that's waste too much time to find out you have a bad BCM..
