Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Chevrolet Suburban, Tahoe, Silverado, or GMC Sierra? Flickering lights, a dead instrument cluster, unresponsive power windows, or a malfunctioning security system are common indicators of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a wide range of confusing and disruptive problems. This genuine OEM-quality GM BCM, part number 25844480 (interchangeable with 15901388), is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Is Your Vehicle Showing Signs of BCM Failure?
A failing BCM can manifest in numerous ways, often making diagnosis difficult. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- ✔ Intermittent or total loss of power windows, door locks, or interior lighting.
- ✔ HVAC controls not working correctly, or the blower motor behaving erratically.
- ✔ The security system acting up, causing no-start conditions or random alarm triggers.
- ✔ An airbag warning light on the dash, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Erratic wiper operation or other strange electrical behavior that seems to have no clear cause.
- ✔ Multiple communication DTCs stored in various modules.
Installing Your 2007-2011 Suburban BCM
This module is engineered for a straightforward installation, typically located under the driver’s side dashboard near the steering column. The process is simple, but post-installation steps may be necessary. While our VIN programming handles the majority of the setup, some vehicles may require an ‘SDM Key Relearn’ using a professional scan tool if the airbag light persists. This syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position relearn might be needed. This replacement 2007-2011 Suburban BCM restores the communication pathways that keep your vehicle’s accessories operating as intended from the factory.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the HVAC system.
Do I need to take this part to a dealer for programming?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This ensures it works correctly right out of the box, saving you a trip to the dealership and additional programming fees.
Where is the BCM located on my 2008 Chevy Silverado or Suburban?
On most 2007-2013 GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, usually to the left of the steering column. It’s a black box with several large electrical connectors.
What if my airbag light is on after I install the new BCM?
If the airbag light is illuminated, you will need to perform an ‘SDM Primary Key Setup’ using a compatible high-level scan tool. This procedure syncs the new BCM with the existing airbag control module (SDM) and is a required security step on these vehicles.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without any extra fees or the hassle of returning it.
Will this fix a B1001 code?
Yes, a faulty BCM is a very common cause of a B1001 ‘Option Configuration Error’ code. Replacing the module with this VIN-programmed unit will resolve the code, though the SDM Key Setup may be required to clear the corresponding airbag light.
