Post-Installation Information
While this module is designed for a simple installation, some GM vehicles may require additional steps after the part is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. On the Hummer H2, it’s located on the left-hand (driver’s side) firewall. Since our module comes pre-programmed, you avoid the complex step of software flashing.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to load the correct software for your specific vehicle before shipping the part.
What if my airbag light is on after installation?
This is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
