Are you battling frustrating electrical issues in your GM truck or van? Flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. Restore full functionality and peace of mind with our pre-programmed BCM, a direct-fit solution for your vehicle.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would randomly turn on while driving, the radio would shut off, and the power locks would cycle on their own. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with various modules. The culprit? A failing BCM was flooding the data network with garbage information. Installing a pre-programmed BCM like this one solved every single issue in under an hour. It’s a common failure point that often gets misdiagnosed.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Horn not working or honking randomly.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminating for no reason.
- ✔ Communication issues between various electronic modules.

Installation and Post-Install Notes
Installation is straightforward for a DIYer with basic tools, typically located under the steering column on trucks or in the center dash on vans. While our programming handles the majority of the setup, please be aware of these potential post-installation requirements:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this BCM difficult to install?
For most models, the BCM is accessible under the dashboard and can be replaced with basic hand tools. Because we pre-program it to your VIN, you avoid the complex and expensive programming steps required by the dealership.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information to ensure correct programming.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
