From the Diagnostic Bay
n
We had a 2011 Sierra Denali in the shop with a classic case of BCM failure. The owner had already replaced the battery and checked fuses, but the dash lights would flicker randomly and the radio would cut out. After confirming power and ground to the module were solid, we knew the internal logic had failed. Installing a VIN-programmed BCM like this one solved every single issue in under 10 minutes. The customer was thrilled to have their truck back to normal without a costly trip to the dealership for programming.

While installation is simple, be aware that on some vehicles, an airbag light may persist. This can be cleared using a professional scan tool with the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with the airbag system. For a reliable repair, it’s always wise to check for and correct any poor ground connections when replacing your 2011 Sierra Denali BCM.

Frequently Asked Questions
What does this Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and HVAC fan speeds.
Will I need to have this module programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping it to you. This allows for a simple, plug-and-play installation without requiring any additional dealership programming.
Where is the BCM located on my 2011 Sierra Denali?
The Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. Installation usually takes just a few minutes.
My airbag light is on. Will this fix it?
A failing BCM can cause the airbag light to come on. While this module will fix the root cause, you may need to perform an ‘SDM Key relearn’ or ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to turn the light off after installation.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your old, faulty module, making the replacement process faster and more convenient for you.
