Why Choose Our Programmed 2003-2007 Hummer H2 BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair by programming the module with the latest GM software updates matched directly to your H2’s VIN. This ensures all vehicle options and systems communicate correctly from the moment you plug it in, eliminating the need for a costly trip to the dealership for programming.
Installation and Post-Install Considerations
Installation is straightforward for the average DIYer. The BCM is typically located on the driver’s side, under the dashboard near the steering column. Simply disconnect the vehicle’s battery, carefully unplug the electrical connectors from the old module, remove it, and install the new one. Reconnect the battery and start the vehicle. While our programming handles the majority of the setup, 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.
This module is a direct replacement for a wide range of GM part numbers, including: 15116066, 10383536, 15136225, 15136877, 15137394, 15198116, and more, ensuring broad compatibility with many GM trucks and SUVs from this era.
