Are you chasing electrical gremlins in your GM truck or SUV? Intermittent power windows, a flickering dash, or an A/C system with a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and hard-to-diagnose issues. This OEM-quality replacement, part number 15284816, is the definitive solution for restoring order and reliability to your vehicle’s essential functions.

We pre-program each 2007-2011 GM Body Control Module to your vehicle’s specific VIN, ensuring it communicates flawlessly with your existing systems right out of the box. This critical step eliminates the need for expensive dealership programming, saving you time and money and getting you back on the road faster. It’s designed to be a direct-fit replacement for a wide range of popular GM models, including the Chevrolet Silverado, GMC Sierra, Tahoe, and Cadillac Escalade.
Case Study: The 2008 Silverado’s Ghost
A customer brought in a 2008 Silverado 1500 with a laundry list of bizarre symptoms: the radio would cut out, the driver’s side power window worked only when it wanted to, and the airbag light was on. Initially, we suspected a bad ground—a common issue on these trucks. After cleaning and tightening all major grounding points with no change, we scanned for codes. We found a B1001 for the airbag system and a slew of communication errors. This pointed directly to the BCM. After installing a VIN-programmed module, every single issue was resolved instantly. It’s a perfect example of how one failing module can mimic multiple unrelated problems.
Is Your GM Truck or SUV Showing These Electrical Gremlins?
- ✔ An airbag warning light that won’t turn off, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Unresponsive or erratic HVAC controls, including a blower motor that won’t turn on or off.
- ✔ Power windows, door locks, or interior/exterior lights that fail to operate correctly.
- ✔ Security system malfunctions, leading to no-start conditions, stalling, or random alarms.
- ✔ A dashboard lit up with various warning lights and communication-related DTCs.
- ✔ Poor grounding symptoms that persist even after cleaning chassis grounds.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the Module: The BCM is typically found under the driver’s side dash, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Swap the Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Plug them securely into your new module.
- ✔ Mount the New BCM: Secure the new module in the same location as the original. Reinstall any panels you removed.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, windows, locks, wipers, and HVAC to confirm the repair.
- ✔ Post-Install Checks: If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Some models may also require a ‘Brake Pedal Position Relearn’ procedure.

Frequently Asked Questions
What does a VIN-programmed BCM mean for me?
It means the module arrives ready for installation with no extra steps. We load your vehicle’s specific information onto the module before shipping, so it works correctly with your security system and options, saving you a trip to the dealership for expensive programming.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis is best. This often involves checking for specific BCM-related trouble codes with a quality scanner and verifying power and ground signals at the module. If multiple, seemingly unrelated electrical systems are failing, the BCM is a prime suspect.
Will I need special tools for the installation?
For the physical swap, you’ll only need basic hand tools like a socket set or screwdriver to remove dash panels. However, if the airbag light stays on after installation, a professional-grade diagnostic tool is required to perform the ‘SDM Key Sync’ procedure.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any hassle or need to return it.
What is the ‘Setup SDM Primary Key in BCM’ procedure?
This is a security handshake between the new Body Control Module (BCM) and the existing Sensing and Diagnostic Module (SDM), also known as the airbag module. If they aren’t synced, the airbag warning light will stay on. This procedure uses a scan tool to establish that connection and clear the light.
