Common Symptoms of a Failing 2008-2009 HUMMER H2 BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights.
- ✔ Instrument cluster warning lights (like the security light) staying on.
- ✔ The vehicle’s security system preventing it from starting.
- ✔ Communication issues with diagnostic scan tools.
- ✔ Unresponsive key fobs or remote start functions.

Installation and Post-Install Considerations
Installation is typically straightforward, involving disconnecting the vehicle’s battery and swapping the old module with this new one. The BCM on the 2008-2009 Hummer H2 is located on the left-hand (driver’s side) firewall. However, after installation, some vehicles may require additional steps to ensure all systems are synchronized:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
