Restore Full Electrical Function to Your GM Truck or SUV
Are you battling bizarre electrical issues in your Chevrolet Silverado, Tahoe, or GMC Sierra? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or random warning lights are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. This OEM-quality replacement BCM, part number 15284816, is the definitive solution, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2010 Silverado 1500 in the shop that was driving the owner crazy. The radio would cut out, the power locks worked only half the time, and the ‘Service Airbag’ light was constantly on with a B1001 code. After confirming the battery and main grounds were solid, all signs pointed to the BCM. We installed one of our VIN-programmed modules, and it was like flipping a switch. Every function returned to normal immediately. The customer was thrilled to have his truck back without a costly trip to the dealership for programming.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- ✔ Intermittent or completely dead HVAC controls and blower motor function.
- ✔ Power windows, door locks, or interior/exterior lights not working correctly.
- ✔ An active airbag warning light, often with DTC B1001.
- ✔ Security system errors, causing no-start conditions, stalling, or misfires.
- ✔ A variety of seemingly unrelated diagnostic trouble codes (DTCs).
- ✔ Problems with windshield wipers or other accessory circuits.

This critical step ensures that the module communicates perfectly with your truck’s other systems right out of the box. We load the latest GM software updates, which can resolve issues that were present even in the original factory programming. This module is a direct replacement for a wide range of part numbers, including 15284816, 25844480, 25835966, 15943678, 20939137, and 22860591, making it a versatile fix for many 2007-2013 GM trucks and SUVs.
Installation and Post-Install Considerations
Physically installing the BCM is straightforward. It’s typically located under the driver’s side dashboard, near the steering column, and can be swapped in under 5 minutes. While our VIN programming handles the majority of the setup, some vehicles may require additional steps:
- Airbag System Sync: If the airbag warning light appears after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your old module without the hassle of returning it. By choosing our pre-programmed 2007-2011 Silverado BCM, you’re not just buying a part; you’re buying a complete, hassle-free solution to get your truck back in top shape.
Frequently Asked Questions
What does a Body Control Module do in a 2007-2011 Silverado?
The BCM is the central computer for your truck’s body electronics. It controls functions like the interior and exterior lights, power windows, door locks, HVAC system, security system, and wipers.
Is this BCM difficult to install?
The physical installation is very simple and usually takes less than 5 minutes. It’s located under the dash and is easily accessible. Our VIN programming eliminates the need for complex computer setup, making the process much easier than with an unprogrammed module.
Do I need to take my truck to the dealer after installing this part?

My airbag light is on after installation. What should I do?
