Are you battling frustrating electrical problems in your GM truck or van? A faulty Body Control Module (BCM) is often the culprit behind a host of baffling issues, from flickering lights and malfunctioning power accessories to a vehicle that won’t start. The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can create chaos. This replacement BCM is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN.
Common Symptoms of a Failing GM BCM

- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Gauges on the instrument cluster behaving erratically or not working.

Installation and Post-Install Requirements
Installation is typically straightforward, as the BCM is located under the steering column on most trucks or in the center dash on vans. However, after installing your new BCM, some vehicles may require additional electronic handshakes to ensure all systems communicate correctly.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions to reply with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Is this part truly plug-and-play?
For most functions, yes. Because it comes pre-programmed to your VIN, it will operate the core systems upon installation. However, as noted, certain systems like the airbag (SRS) or brake sensor may require a simple relearn procedure with a capable scan tool.
What if my airbag light comes on after I install it?
This is a normal possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag module (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module.
Will this fit my Crew Cab truck?
This specific BCM is for models excluding Crew Cab configurations for most pickup models listed. Please carefully check the fitment details to ensure compatibility with your exact truck or van.
