Is Your HUMMER H2 Plagued by Electrical Gremlins?
If you’re dealing with bizarre and unpredictable electrical issues in your 2008-2009 HUMMER H2, a failing Body Control Module (BCM) is the most common culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights and security system. When it starts to fail, it can cause a cascade of frustrating problems that are difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Vehicle security system faults or random alarm activation.
- ✔ A/C and heater controls not responding correctly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ Intermittent no-start condition, often with a security light illuminated.
The Plug-and-Play Solution
Don’t let a faulty BCM keep your H2 off the road. This is a direct replacement HUMMER H2 Body Control Module, part number 15093910, that arrives at your door pre-programmed for your specific vehicle. We use your Vehicle Identification Number (VIN) to load the latest GM software, ensuring a perfect match to your vehicle’s options and configuration. This eliminates the need for an expensive trip to the dealership for programming.
Post-Installation Information
Installation is straightforward, but in some cases, minor follow-up procedures may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor relearn might be necessary.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related electronic functions, such as lights, power windows, security systems, door locks, and climate controls.
Is this part ready to install out of the box?
Yes! We program the module with the latest GM software using the VIN you provide. This makes the installation process much simpler, though some vehicles may require minor post-installation relearn procedures as noted.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note to your order or reply to your order confirmation email with the information. We cannot ship the part until we have programmed it.
What if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix all of my H2’s electrical problems?
This module will correct all issues directly caused by a faulty BCM. However, it’s important to ensure your vehicle’s issues are not from other sources like a weak battery, bad grounds, or faulty wiring before ordering.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
