Are you battling frustrating electrical gremlins in your GM truck or SUV? Intermittent power windows, a malfunctioning security system, or a dashboard lit up with warning lights often point to a single culprit: a failing Body Control Module (BCM). This OEM-quality BCM, equivalent to part number 15284816, is the central command unit for your vehicle’s body electronics. We pre-program it to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation that restores function and eliminates the need for a costly dealership visit.
Is Your GM Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways, often making diagnosis difficult. If you’re experiencing any of the following, a replacement module is your most likely solution:
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or climate controls that don’t work.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, including random alarm activation or a no-start condition.
- ✔ Stalling, misfires, or poor grounding that can’t be traced to other components.
- ✔ A variety of communication-related DTCs stored in the vehicle’s computer system.
The Plug-and-Play Solution: A Pre-Programmed Sierra 2500 Body Control Module
This isn’t just a replacement part; it’s a complete solution. The primary hurdle in BCM replacement is the mandatory programming. We handle that for you. By programming the module to your VIN before shipping, we ensure it communicates perfectly with your truck’s other electronic systems right out of the box. This module is built to strict OEM standards for reliability and is backed by a one-year warranty, giving you peace of mind whether you’re on the job site or on a family road trip. It directly interchanges with a wide range of part numbers, including 25835966, 15263363, 15943678, 25971916, and 22860591, making it a versatile fix for many 2007-2013 GM vehicles.
Installation and Post-Install Considerations
Physically installing the Sierra 2500 Body Control Module is straightforward. It’s typically located under the driver’s side dashboard near the steering column and can be swapped in minutes. However, be aware of two potential post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Best of all, there is absolutely no core charge. You can keep your old part without any hassle or extra cost. Get your truck’s essential systems working reliably again with this simple, effective solution.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and HVAC controls.
Is this module ready to install when I receive it?
Yes! We pre-program the module to your vehicle’s VIN before shipping. This ensures it’s ready for a plug-and-play installation without requiring a trip to the dealership for programming.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified technician can perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to resolve this.
Do I need to return my old, faulty BCM?
No. There is no core charge or requirement to send your original part back to us. You can keep it or dispose of it at your convenience.
