Are you experiencing frustrating electrical issues with your 2008-2009 Hummer H2? Bizarre problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up are often traced back to a single component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of confusing and intermittent symptoms. Restore your vehicle’s functionality and peace of mind with our pre-programmed, direct-fit replacement BCM.
This isn’t just a generic part. We program each module specifically to your vehicle’s VIN using the latest software updates from GM. This ensures seamless integration and proper function of all your vehicle’s features, right out of the box. Simply provide us with your VIN after purchase, and we’ll handle the complex programming before we ship it to you. This eliminates the need for an expensive trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Warning lights appearing on the dashboard for no apparent reason.
- ✔ The radio or climate control system behaving unpredictably.
- ✔ A no-start condition where the engine cranks but won’t fire up due to security system issues.

Installation and Post-Install Notes
While installation is straightforward for many DIY mechanics, some post-installation procedures may be necessary depending on your vehicle’s specific configuration. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control function, a brake pedal position sensor relearn might be required.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic functions, such as power windows, locks, lights, security system, and wipers. It acts as a central hub for these systems.
Do I need to program this Hummer H2 Body Control Module?
No. We program the module for you before shipping. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready to be installed.
Where is the BCM located on a 2008-2009 Hummer H2?
On the 2008-2009 Hummer H2, the Body Control Module is typically located on the driver’s side, attached to the LH firewall area, often behind the lower dash panel.
What information do you need from me?
We need your vehicle’s 17-digit Vehicle Identification Number (VIN) to program the BCM with the correct software and settings for your H2’s specific options.
What if my airbag light comes on after I install it?
This is a possibility. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us.
