Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we pre-program the module to your vehicle’s specific VIN before it ships. This makes the installation plug-and-play, saving you the time, cost, and hassle of a dealership visit.
What if my airbag light stays on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is done through a procedure called ‘Setup SDM Primary Key in BCM’ which requires a professional-grade scan tool. This is only necessary if the airbag light appears after the new BCM is installed.
Where is the BCM located on my Avalanche 2500?
On the 2002-2006 Chevrolet Avalanche 2500, the Body Control Module is located under the driver’s side of the dashboard, near the steering column. It’s a black box with several large electrical connectors.
Is this a difficult part to install myself?
For most DIYers, this is a very simple installation. It typically involves removing a lower dash panel for access, disconnecting the negative battery terminal, unplugging the electrical connectors from the old BCM, unbolting it, and then reversing the process. The entire job can often be completed in under 10 minutes.
Will this module fit other GM trucks and SUVs?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade, and Hummer H2. Please verify the part number or use our vehicle fitment tool to ensure it is correct for your specific model.
Do I need to send my old part back?
