2014 qx70 3.7l. Car off, doors closed, key out, wait 30 mins and im getting a consistent draw of 250 milliamps from the battery. I have found the circuit that lowers that down to 60 milliamps. The room lamp circuit inside the car. Removal of 10a fuse drops the voltage. I disconnected each light on each door throughout the interior of the car 1 at a time and checked voltage. None of these dropped the voltage. The overhead lights didnt and neither did the glove box. The door actuators are working correctly. If all of those disconnects do not drop voltage, am I testing correctly or is the bcm really the issue? (Hopefully not). How can I test the bcm before it reaches the fuse? Back probe the harness on the back of the interior fuse box maybe? Or at the bcm? What would your next logical steps be?
