- Intermittent or non-working power windows, door locks, or interior/exterior lights.
- HVAC controls that are unresponsive or a blower motor that works sporadically.
- An airbag warning light that won’t turn off, often accompanied by DTC B1001.
- Security system malfunctions, causing no-start conditions or stalling.
- A host of seemingly unrelated diagnostic trouble codes (DTCs) related to body electronics.
This VIN-programmed module is the definitive solution, designed to be a direct replacement for your original part. By ordering a pre-flashed unit, you eliminate the need for expensive dealership programming, making this the most efficient and cost-effective way to fix your 2011 GMC Sierra Denali 1500 BCM and get back on the road.

Expert Insight from Our Technicians
Before you replace your 2011 GMC Sierra Denali 1500 BCM, take a moment to inspect the main ground connections, especially the one located on the driver’s side frame rail beneath the door. On these GM platforms, a corroded or loose ground can cause erratic voltage and mimic the symptoms of a failed BCM. Cleaning and securing this connection is a 10-minute job that can sometimes solve the issue. If the problems persist after checking the ground, you can be confident that the BCM itself is the root cause.
Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we flash the module with your vehicle’s unique 17-digit Vehicle Identification Number (VIN) before shipping it to you. This ensures the BCM has the correct software and configuration for your specific options, allowing it to communicate perfectly with your truck’s other computers right out of the box.
Is this a difficult part to install myself?
For most DIYers, this is a straightforward installation. The BCM is typically located under the driver’s side dashboard near the steering column. It usually takes less than 15 minutes to swap out. No special tools are required beyond basic hand tools to remove the lower dash panel.
My airbag light is on. Will this BCM fix it?
If the airbag light is caused by a BCM communication error (like DTC B1001), this replacement module will resolve the root cause. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system and clear the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module, which saves you the hassle and expense of shipping it back.
How can I be sure this part fits my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs. The best way to confirm is to match the part number from your original BCM to one of the compatible numbers listed, such as 25790509. Providing your VIN at checkout guarantees we will program and send the correct part for your exact 2011 GMC Sierra Denali 1500 BCM configuration.
