Installation and Post-Install Notes
While installation is straightforward, some GM vehicles may require a simple relearn procedure. If the airbag warning light is illuminated after installing the new BCM, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new module with the airbag system. In some cases, a Brake Pedal Position Relearn may also be needed to ensure proper brake light and stability control function. Always consult a service manual or qualified technician if you are unsure. This is the direct solution for a faulty 2011 Sierra Denali BCM, getting you back on the road safely and quickly.
Frequently Asked Questions
What does the Body Control Module do on my 2011 Sierra?
The BCM is the main computer for your truck’s comfort and convenience features. It controls the power windows, door locks, interior and exterior lighting, wipers, security system, and HVAC climate controls.
Why is VIN programming so important?
VIN programming loads your truck’s specific configuration and software into the BCM. Without it, the module won’t know which features your vehicle has (like power-folding mirrors or specific lighting packages), leading to incorrect operation. Our pre-programming service makes it a true plug-and-play part.
Can I install this BCM myself?
Yes, for many DIYers, this is a simple installation. The BCM is typically located under the steering column and is held in by a few clips or bolts. The entire swap can often be done in under 15 minutes with basic hand tools.
Will this fix my airbag light that’s on with code B1001?
A faulty BCM is a common cause of the B1001 code. Replacing it will likely solve the root problem, but you will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure after installation to sync the modules and turn off the light.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for a wide range of part numbers, including 25844480, 25835966, 15943678, 20939137, 22860591, and more. It is designed for many 2007-2013 GM trucks and SUVs.
