For an oil change it doesnt need to be removed.
However if you are going in for programming or diagnostic work the CAN wires MUST be removed. Map 0 is not sufficient enough. The system will not read the vehicle, it will try to connect and not detect the VIN. You can manually enter the VIN but it still will not connect and give an error to the tech. CAN wires need to be removed, everything else can stay connected.
