Frequently Asked Questions
What does a Body Control Module do on a Sierra Denali?
The BCM acts as the central computer for your truck’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC blower motor, ensuring all these convenience and safety features work together correctly.
Is this BCM difficult to install?
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. Since our module is pre-programmed, no complex computer work is needed for the initial setup.
Do I need to take my truck to the dealership after installation?
In most cases, no. Our VIN programming handles the primary setup. However, if your airbag light remains on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system. This is a common step for this vehicle platform.
How do I know this is the correct BCM for my truck?
This module is a direct fit for the 2003-2007 GMC Sierra Denali Body Control Module. It also cross-references with numerous other part numbers listed in the product details. To ensure a perfect match, you can compare the part number on your existing BCM with our list of compatible numbers or provide us with your VIN at checkout.
What if my key fob doesn’t work after installation?
While the VIN programming handles most functions, key fobs may occasionally need to be re-paired to the new BCM. This is a simple procedure that can typically be found in your vehicle’s owner’s manual or online and does not require special tools.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old module back to us, which makes for a simpler and faster repair process.
