Is Your GM Truck or SUV Plagued by Baffling Electrical Problems?
If you’re dealing with flickering lights, a non-responsive climate control system, or power windows with a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and seemingly unrelated issues. This VIN-programmed BCM, part number 15901388, is the definitive solution to restore full electrical functionality to your 2007-2013 GM vehicle, including the Cadillac Escalade, Chevrolet Silverado, GMC Sierra, and more.
Symptoms of a Failing Body Control Module
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or stays stuck on high.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions, stalling, or random alarm activation.
- ✔ Intermittent instrument cluster behavior or warning messages.
- ✔ Communication errors with other vehicle modules, causing a variety of performance problems.

Installation and Post-Install Considerations
Physical installation is straightforward. The BCM is 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 primary setup, some vehicles may require additional relearn procedures. If the airbag light remains on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ function with a professional-grade scan tool. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure proper brake light and traction control operation. These procedures are simple for any qualified shop to perform.
Frequently Asked Questions
What does this Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls features like your power windows, door locks, interior and exterior lighting, wipers, security system, and HVAC fan speeds.
Is this part truly plug-and-play?
Yes, this module comes pre-programmed to your vehicle’s VIN for a plug-and-play installation. However, as with any BCM replacement, certain models may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be done with a capable scan tool.
Will this fix my airbag light with a B1001 code?
A faulty BCM is a common cause of the B1001 code. Replacing it with our programmed module should resolve the root cause. If the light stays on after installation, the ‘Setup SDM Primary Key’ procedure is required to sync the new BCM with the airbag system.
Do I have to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees or hassle.
Where is the BCM located on my 2008 Chevy Silverado or GMC Sierra?
On most compatible GM trucks and SUVs from this era, including the Silverado, Sierra, Tahoe, and Escalade, the BCM is located under the driver’s side of the dashboard, usually to the left of the steering column.
