Expert Insight from Our Technicians
As veteran mechanics, we’ve seen countless GM trucks and SUVs suffer from frustrating BCM failures. One of the most overlooked aspects during replacement is the vehicle’s grounding system. Before installing your new 2007-2011 Avalanche 1500 Body Control Module, take a few extra minutes to inspect and clean the main ground points under the dash and on the A-pillar. A poor ground can cause voltage spikes that damage sensitive electronics and mimic the symptoms of a failed module. This simple step can prevent a repeat failure and ensure your new BCM provides years of reliable service.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install, saving you time and money.
How difficult is the installation?
Installation is very straightforward for most DIYers. The BCM is typically located under the driver’s side dashboard near the steering column. It’s a simple process of disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. The entire job can usually be done in under 15 minutes.
What if my airbag light is on after I install the new module?
This is a common occurrence on these GM platforms. If the airbag light persists (often with code B1001), you will need to perform an ‘SDM Key Update’ or ‘Setup SDM Primary Key in BCM’ procedure. This requires a professional-grade scan tool and syncs the new BCM with the vehicle’s existing airbag system. This is a simple procedure for any qualified repair shop.
Will this 2007-2011 Avalanche 1500 Body Control Module fit other GM vehicles?
Yes, absolutely. This module is compatible with a wide range of GM trucks and SUVs from 2007-2013, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. Please check the detailed fitment list on this page to confirm it matches your specific year and model.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can keep your old module, which means no core charge and no hassle with return shipping.
