Are you battling frustrating electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are common 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 cascade of confusing and intermittent issues. This pre-programmed BCM, part number 15194169, is the direct solution to restore full functionality and reliability to your vehicle.
We make the replacement process simple. Unlike the dealership, which requires you to have the vehicle towed in for programming, we program this module to your vehicle’s specific VIN before we ship it. This means that for most vehicles, installation is a straightforward plug-and-play process. Simply provide us with your VIN after purchase, and we’ll handle the software side, loading the latest GM updates for optimal performance.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system faults or the engine not starting due to a security lockout.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers behaving erratically (e.g., won’t turn off).
- ✔ “Service Electrical System” or similar warnings on the dash.
- ✔ Communication loss with other vehicle modules, leading to multiple warning lights.
Installation and Post-Install Procedures
Installation is typically straightforward, involving locating the old BCM (often under the steering column or in the center dash), disconnecting the battery, swapping the modules, and reconnecting everything. However, please be aware of the following potential post-installation steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the BCM actually do on my truck or van?
The Body Control Module acts as the brain for your vehicle’s comfort and convenience features. It controls the power windows, locks, interior/exterior lighting, security system, wipers, and other electronic accessories that aren’t directly related to the engine.
Is this part difficult to install?
For someone with basic mechanical skills, the physical swap is generally easy. The BCM is usually located under the driver’s side dash. Since we program it to your VIN beforehand, it eliminates the need for expensive dealer programming, making it a DIY-friendly repair for many.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. This is crucial for us to program the module with the correct software and vehicle-specific options for a seamless installation.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
What if my airbag light comes on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
