Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep or dispose of your original module, making the process simple and hassle-free.
Is any additional programming required after installation?
In most cases, no. The BCM comes fully programmed for your vehicle’s main functions. However, if your airbag light is on after installation, a simple “Setup SDM Primary Key” procedure may be needed with a professional scan tool to sync the new BCM with the airbag system.
Where is the BCM located on my vehicle?
On most compatible models like the Silverado, Tahoe, and Hummer H2, the BCM is located under the driver’s side dashboard, near the steering column. On Express and Savana vans, it is typically found in the center dash area.
Will this fix my “Service Airbag” light?
If the airbag light is caused by a BCM communication error (like DTC B1001), then replacing the module will resolve the root cause. After installing the new 2003-2007 Hummer H2 Body Control Module, you may need to perform the SDM key sync procedure mentioned above to turn off the light.
What tools are needed for installation?
Installation is straightforward and typically requires only basic hand tools, such as a socket set or nut driver, to remove the lower dash panel for access. The module itself is held in by clips or small bolts and has several color-coded electrical connectors that are easy to unplug and reconnect.
