Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes. We use the VIN you provide during checkout to program the module with the latest GM software specific to your vehicle’s configuration. This ensures it communicates correctly with your truck’s other systems right out of the box, with no additional programming required.
What if my airbag light is on after installation?
In some cases, if the airbag light is illuminated after installing the new BCM, a simple procedure called “Setup SDM Primary Key in BCM” may be needed. This requires a professional-grade scan tool to sync the BCM with the airbag system and turn off the light.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep your old module, which saves you the time and hassle of shipping it back.
How can I be sure my BCM is the problem?
While the symptoms listed above are strong indicators, the best way to confirm is with a proper diagnosis from a qualified technician using a high-level scan tool. A failing BCM often triggers multiple communication-related DTCs. This 2003-2007 Sierra Denali Body Control Module is the direct solution for those confirmed failures.
Will this fit other GM trucks besides the Sierra Denali?
Absolutely. This BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Avalanche, Suburban, Tahoe, Express Van, Cadillac Escalade, and Hummer H2. Please check the compatibility list on this page to confirm the fit for your specific model.
