Simply disconnect the vehicle’s battery, remove the old module, plug in the new one, and reconnect the battery. While the module is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. This syncs the new BCM with the airbag system. There is no core charge, so you can keep your old part without any hassle.
