Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle responsible for managing a wide range of electronic accessories and systems not related to the engine. This includes power windows, door locks, interior/exterior lighting, security systems, wipers, and more.
Is this part difficult to install?
The BCM on the 2008-2009 Hummer H2 is located on the driver’s side, near the firewall. Installation is typically straightforward for someone with moderate mechanical skill, involving disconnecting the battery and swapping electrical connectors. However, some post-install procedures, like an airbag system sync, may require a professional scan tool.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your H2’s specific features and options. This step is essential for a true plug-and-play installation and ensures all systems communicate correctly.
What happens if my airbag light comes on after installation?
In some cases, the new BCM may need to be synchronized with the airbag system’s computer (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a qualified technician with a high-end diagnostic tool to turn the light off.
